For us, the communication component is fundamental during the design phase. Our technicians follow the evolution of the project step by step, always keeping in touch with the customer and proposing the best solution to overcome the various problems detected during the planning and gear design phase. Once the basic lines of the project have been established, the gear is shaped using a 3D CAD software that allows to follow all the different specifications in the best way possible, while for the calculations and 3D models of the evolvents we rely on KISSsoft software, internationally recognized as the best software in this sector. In addition to all the main geometric calculations, this program makes available numerous optimization functions including transmission performance, important data on coating, contact analysis and heat dissipation simulations. Among our services there is also FEM filling analysis which, together with the study of the thermoplastic product deformations and numerous other simulations, allows avoiding mold setup steps, thus considerably shortening the design time. Investments and cutting-edge tools allow us to keep up with the evolution of applied mechanical technology, but they would not be sufficient to achieve the high quality goal if they were not supported by the thirty-year experience of our specialized technicians, able to "read" the collected data, define the feasibility of the required tolerances and propose possible modifications to achieve the maximum precision and quality for gears and transmission parts. Contact us if you are looking for partners with international experience in the planning of transmission parts and gear design, equipped with the cutting-edge systems and machinery. --- The design and construction of molds are focused on ensuring the best production of gears and transmission parts. Our molds are internally designed, a feature that over the years has allowed us to deal with any type of request and to always find the most effective solution: from the simplest, to the most complex molds with trolleys, hot chamber or for co-molding. The professionalism and experience of our technicians allow us, in collaboration with the customer, to always find the best solution to satisfy all needs. We consider the communication with the customer as a decisive moment in the design and production process of molds since the choice of components to be used - such as HASCO, Pedrotti or Meusburger - depend directly on the specific requests of the customer. Each phase of the design is in fact shared with the customer, in order to obtain the best possible result. Even before the design phase of the real mold, we pay particular attention to the choice and quality of the steels we use in the execution of the mold, to guarantee durability and efficiency. Once the material selection and mold design phase, has been completed, it is essential to proceed with a series of Moldflow simulations. These are used to prevent any type of problem and identify any criticality that may have been missed during the previous phases. In fact, these simulations allow monitoring and establishing certain critical parameters, such as injection points, cooling channels and filling and compacting values, which could negatively affect molding.

It is also possible to choose the most suitable material depending on the type of industrial application of the component. The implementation of our gears, in addition to the benefits regarding productivity reduces significantly all the costs of managing the machinery maintenance; technopolymer is an extremely durable material that requires less frequent maintenance compared to the traditional ones. --- The technopolymer components for machinery equipment can also be used in the residential automation sector. The parts produced for this sector are characterized by lightness and noiselessness. All details related to the technopolymer, a material that is suitable for multiple uses. Our technopolymer gears meet both the standardized demand and specific requests. Our technical office, thanks to many years of experience, is able to design specific items according to customer needs, offering support in selecting the most suitable material for the type of application. The production line dedicated to the residential automation sector consists of gears and transmissions that are used in handling gates, doors and curtains. Also in this case the noiselessness of the technopolymer makes the difference, a characteristic much appreciated by those who have already had the chance to try it. In this sector we produce toothed pulleys, belt tensioners, planetary gears for worm screws, helical gears and racks of all kinds. Designer and leader in the production of technopolymer molded rack for the handling sliding gates, we have also entered the sector of internal transmissions for gate motors. Stagnoli products, thanks to their remarkable resistance to atmospheric agents, have become a reference point also in the field of solar protection automation, since our transmissions do not deteriorate, do not require lubrication and are significantly lighter. Therefore they perfectly match the needs of the sector. --- The light, self-lubricating properties of our gears have allowed us to establish ourselves in the industrial automation and robotics sector, with ideal products for conveyor belts, pick and place machines and automated industrial assembly lines.

Always more frequently, we support the manufacturers of this market in the design and execution of product lines with technopolymer gears. These are some examples: worm screw gearboxes; helical gearboxes; planetary gearboxes; “cycloid” gearboxes. Thanks to the absence of lubrication and the freedom of design allowed by injection molding, we have managed not only to replace brass and steel gears, but to study gearboxes with geometries that are almost impossible to obtain with traditional materials. In many cases the toothing with special profiles has been optimized and ad hoc adjusted to better balance the resistance of the transmission in the specific application where it must be inserted. Other aspects such as heat dissipation or spacing accuracy have also been studied. Many of these products are used in a variety of applications such as automotive (windshield wipers, seat handling), medical (dentist seats, automatic X-ray machines) and Oil & Gas (reducers for the oil industry, or automatic gas valve adjustments). Replacing the materials of the machinery with our technopolymer components is a simple and fast operation. Furthermore we are able to produce custom gears based on the customer's needs starting from the technical design elaborated by our internal study. Stagnoli srl designs ad hoc, reliable and precise solutions for the components of machines used in the field of linear actuator gearboxes and electric motors. --- For over five years, we have designed and manufactured POM helical and toothed gears for applications in the rapidly growing e-bike segment, including transmissions optimized through advanced gear-design research to meet the demands of extreme silence and lack of lubrication. These products have proven to be much more durable than mechanically processed parts, and boast specific advantages for the e-bike sector, such as extreme precision in terms of concentricity and tooth profile, co-moulding with rectified inserts, and resistance to electric motor jolting and general wear. These features make technopolymer transmission parts ideal for the electric bike sector, while guaranteeing lightness, silent operation and reduced maintenance requirements. We also tailor-make e-bike transmission gears, developed from technical drawings by our internal design studio, to customer specifications.

Stagnoli, based in Lonato del Garda in the province of Brescia, is renowned for its excellence in the production of technopolymer gears. It uses innovative materials and offers many significant advantages in the world of automation. Matt Croson's visit made it possible to explore these advanced technologies and to consider future collaborations. --- In a previous news article, we clarified the concept of quality in relation to plastic gears. We defined what it depends on and what instruments are suitable for certifying the degree of precision achieved. In this new article, we will instead take a look at what problems a low-quality technopolymer transmission element or gear can cause. --- Plastic gears are growing increasingly popular and becoming further used in the field of motion and power transmission: their numbers have now surpassed those of metal gears. They are widely used in the automotive industry, for medical applications and even in the space industry. Their widespread use demonstrates the efficiency and precision that they ensure, as they meet the high quality standards of these professional fields. But what is meant by the quality of a gear and its degree of precision? Let's find out together. --- Stagnoli is very excited to announce that it will take part in the prestigious Mecspe 2024 trade fair, an unmissable event taking place from 6 to 8 March. --- Cycloidal drives represent a crucial element of mechanical engineering, especially in the transmission of motion in various industrial contexts. Their compact construction and operational flexibility also make them suitable for applications in confined spaces, thus helping to maximise the efficiency of power transmission systems. Their versatility is crucial in varied and complex industrial scenarios, where speed reduction and motion transmission require technologically advanced and reliable solutions. Their innovative design is based on a roller gear mechanism, which offers significant advantages over traditional drives.   --- Metal insert injection molding has gained popularity in recent years as a cost-effective and efficient manufacturing process.

The quality of Stagnoli’s products, its 100% Made in Italy production, the use of innovative materials and high quality standards are just some of the characteristics that make us a leading company in the industry. Thanks to our know-how and the greater catalog of transmission components in technopolymer, today Stagnoli has reached another very important achievement: becoming an EPTDA member! --- VDI Munich 2023 is the international conference on gears, now in its tenth year! The event will be held from 13th to 15th September 2023 in Garching, Munich, at the Gear Research Center (FZG) of the University of Munich. --- The use of metal components in the food industry can be an impractical and resource-intensive choice. In fact, metal gears must be subject to regular maintenance as they could contaminate foodstuffs in industry production owing to the most common corrosion phenomena. In addition, there is also the contamination caused by the products required for lubricating the moving parts. This is why, in recent years, the pursuit of alternative plastic materials that could overcome these problems has taken off. PEEK is definitely the star of this revolution, used in the chemical industry and many other sectors, including the food industry. PEEK is a material capable of remaining unaltered even in environmental situations where most metals, including noble alloys such as corrosion-resistant steels, fail in a short time. It ischaracterised by its excellent resistance to high temperatures (up to 260°) and resistance to radiation (X-rays and gamma rays), which makes it the ideal solution in certain applications and as a replacement for metallic materials. Moreover, it is a material suitable for food contact as it is highly resistant to sterilisation cycles. Its only disadvantage is the cost per kg, which is higher than commercially available technopolymers. This aspect severely limits its use. --- Conveyor belts and roller conveyors represent an essential part of the production chain. In departments where raw materials must be continuously supplied to maintain constant production, having facilities that provide real support, resistance and performance is paramount. --- The helical gear wheel mechanism – worm screw – is used in motion transmission between two orthogonal oblique shafts when a large reduction in the speed of the driven shaft is required in limited space. The screw is always driving, the wheel is always driven. The number of screw principles determines the transmission ratio. For example, with a one-principle screw, the wheel moves one tooth with each turn of the screw. The efficiency of this coupling is, however, very low owing to high levels of rubbing, which causes high power loss and wear. This is certainly a weakness of metal materials. Recently the growing pursuit of ever-greater performances in the applications that involve worm gear transmission has led to the use of technopolymers. Given the complexity of the phenomenon, which includes both the challenges of precision mechanics and physical and thermal phenomena related to plastic materials, choosing a reliable partner is key. --- The viability of thermoplastic gears for low loads at low transmission power is consolidated thanks to the number of advantages that plastic components offer compared to metal, such as: --- Stagnoli is a leader in the field of technopolymer gears. We have become a benchmark for companies seeking to prioritise product innovation, with numerous advantages in terms of both production and performance. --- Over the past decade, the packaging sector has benefited from the automation of processes, with ever more appliances for robotic packaging. Growing automation in industrial manufacturing has led a strong increase in the demand for components. This growing demand is combined with a desire to improve the performance of machinery, firstly by seeking more effective materials. In this context, technopolymer transmission devices have gained wide usage. Our company fits perfectly in this scenario as a leader in the sector. We have long experience in the moulding, processing and production of technopolymer mechanical components. We offer customers our know-how and meticulous attention in the design of high-performance mechanical components that are incredibly precise. --- Sales of pedal-assisted bicycles have soared by 20%, with 40,000 more e-bikes sold, according to Confindustria Ancma. As the country emerges from the Covid pandemic, 30% of Italians have expressed an interest in buying an electric bicycle. Increasing concern about sustainability and the desire to reduce the environmental impact of one's means of transport are the factors driving such figures. --- In a modern sports or competition car, active aerodynamics play a fundamental role. Active aerodynamics are a set of motorized parts that come into play, change shape, height or inclination to balance the trade-off between efficiency and downforce in a particular driving situation. The most common active aerodynamic features include: An active front grille that responds to the cooling needs of the engine, electric motor or battery behind it. This system generally consists of fins moved by an actuator. At lower speeds, the motor or electrical components are generally less stressed and require minimal cooling. As a result, the active grille is in the closed position, and the closed surface improves aerodynamics. At higher speeds, or in situations where components are under higher load, the fins or vanes open to ensure that the right amount of air can pass through and provide the necessary cooling. Active splitters work to increase the downforce applied to the front of the car, helping push the wheels down onto the asphalt and provide more grip. In most cases, an active front splitter actually forms a part of the car’s front bumper, connected by a series of actuators. When required (typically at higher speeds, where greater downforce offers greater dynamic benefits), these actuators are able to extend the front bumper under the rest of the bodywork, increasing the downforce applied via the ground effect. A spoiler, by being able to exploit the different inclinations of its flap, is able to accentuate the aerodynamic load so as to improve stability in high-speed cornering, or reduce the load and, above all, air resistance so as to make the most of acceleration and the maximum speed of the car. Similarly, the spoiler can also be raised entirely, significantly increasing the downforce and aerodynamic resistance, to act as a brake assisting normal hydraulic brakes. Such changes in profile are generally automated or controlled from inside the car via a button, and are powered by hydraulic or pneumatic actuators. --- With the aim of fully meeting our client’s demands, consolidating and enhancing competition, our company constantly invests to improve its products, its processes and the quality of its services. With this target in mind, recently Stagnoli Gears has extended its machinery park in its headquarters in Lonato del Garda, with insertion of a vertical injection press mainly dedicated to moulding plastic gears and, specifically, co-moulding of metal inserts. Co-moulding includes use of a part (often metal), which is placed inside the mould in the phase before injection. Stagnoli Gears innovates and renovates its machinery park: performance, quality and precision The increasingly strict requirement for precisions in injection moulded transmission units means optimising all the variables in play in the entire process chain. The type of press is based on the geometry of the component. --- It has emerged from recent research that people pass most of their time in indoor surroundings. For this reason, indoor surroundings can be up to five times more polluted than outdoor ones. To guarantee the quality of life of our host spaces, quality must be ensured of indoor air. Quality of indoor air is intended as the impact the air can have on the personal comfort and well-being of those living in it (living and performing activities) in spaces in which the air circulates. To obtain an ideal micro-climate inside buildings, using sustainable comfort and respecting the environment, today the market offers advanced system solutions identified at international level by the code HVAC. What are HVAC systems and what benefits do they offer? HVAC stands for Heating, Ventilation and Air Conditioning. They are solutions that aim to provide technologies capable of optimising performance of the heating, ventilation and conditioning systems, guaranteeing: Energy savings; Operational efficiency; Reduction in environmental impact. HVAC systems include the set of heating, ventilation, conditioning of air and refrigeration systems. The particular feature of this technology is the grouping of the interconnected mechanical systems, such as air conditioning units, boilers, air purifiers and heat pumps. Each system contributes to the same objective, i. e. optimising management of indoor comfort. A leader in design and production, not only in technopolymer gears, but also in mechanical systems that are the basis of these technologies, Stagnoli Gears is the perfect partner to make gears for innovative and high performance HVAC systems. --- Stagnoli has been working for over forty years in the production of transmission elements in the construction of technopolymer gears, offering a vast range of standard or design-based products. In fact, the company in Lonato del Garda, can customise its catalogue range by carrying out mechanical machining of gears in the post-moulding phase, according to the specific needs of each client. Construction of made-to-measure gears: a dedicated Stagnoli service Stagnoli has a vast and structured production: the catalogue (downloadable here) presents a clear and complete overview of the components, precision gears and transmission units in technopolymer. Just under 50 pages recall our working method and the results of our constant commitment to always provide the client with the most performing solution, for silent, light, self-lubricating and high performance gears. --- With 20 editions behind it, MECSPE 2022 is the most anticipated date in the manufacturing industry. Dedicated to technological innovations in the production chain, it is a truly important event in which Stagnoli Gears cannot wait to take part, with its technopolymer racks! --- Our specialisation in the design and manufacturing sector of reducers and transmission units in injection moulded technopolymer require high level precision. This requirement can be exclusively obtained by operating qualitatively excellent production cycles and applying continuous improvements in each company process. This is the spirit with which collaborators operating in Stagnoli work each day to maximise corporate results. Stagnoli is a reference point in its field which has enabled it to become a partner for the leading companies in the main markets, including the automotive sector which is renowned as one of the strictest markets in terms of qualitative standards of its processes and products. Following continuous development in the company and market requests, we decided to make our high qualitative standards official. --- The design of moulds is a complex business where taking into consideration the different technical, aesthetic and dimensional requirements is fundamental, especially during the engineering phase. Stagnoli Gears precision moulds: absolutely guaranteed The optimal performance of plastic and technopolymer component design inevitably passes from precise and accurate design of the equipment and precision moulds to use in the production cycle. The main difficulties of our operating sector and in the design of precision moulds are essentially two: Take into consideration all the technological aspects of technopolymer transformation (temperatures, thicknesses, deformations); Consider the application field in which our transmission units in technopolymer operate: precision mechanics. Keeping these aspects in mind is highly important to guarantee precision and accuracy in each phase of the process, starting from the in-depth design of the precision moulds. --- Our company was established forty years ago based on a revolutionary idea: the merging of metal replacement and the concept of co-moulding in the transmission elements sector. This idea led to a patent of the technopolymer rack with a steel core. A goal we safeguard with pride, which gives our company over forty years of know-how and the skills that enable us to stand out as the leading company in the sector of transmission units in technopolymer of co-moulded gears with inserts. Metal replacement and co-moulding by Stagnoli Gears Over the years, the metal replacement and co-moulding market has become increasingly aggressive and competitive, taking inspiration from our ideas and in particular reproducing our flagship product. The benefit of being the first however translates into increasingly expanding development of new, innovative products which has led to an expansion of our range of catalogue items: today, we offer all our clients the possibility of having an immediate and reliable turnkey solution for their applications. --- The helical toothed rotary mechanism – worm screw – is used in motion transmission between two orthogonal oblique shafts when a strong speed reduction is necessary of the driven shaft in limited dimensions. The screw is always driving, the wheel is always driven. Depending on the number of principles of the screw, the transmission ratio is obtained. For example, if the screw has a principle on each turn of the screw the wheel moves by a tooth. The screw gear is a strong speed reducer that overcomes great resistance with small power. The performance of this coupling is however low due to rubbing and therefore high wear. This definitely represents a weakness in metal materials. Plastic worm gears by Stagnoli Gears This is the perfect context for our company, the leader in the design of gear reducers in technopolymer. Our experience and precision design of the geometry of the screw and the gear in plastic allow us to guarantee numerous solutions. The freedom of design granted by injection moulding has not only allowed us to replace brass and steel gears, but also research gears with geometries that are almost impossible to obtain with traditional materials. In many cases, teeth with special profiles have been optimised, corrected ad hoc to better balance the resistance of the transmission in the specific application in which it is inserted. --- Lately, there is increasing talk about the future of gears for farm machinery and market trend, especially in terms of new sustainability policies implemented in the European Union to face climate change and reduce its consequences. Discussing sustainability implies also dealing with the issue of manufacturing transmission units and chain tensioner pinions with innovative design rather than the traditional concept. Stagnoli has always been advanced from this point of view since it has been providing gears and chain tensioner pinions in technopolymer for years in the farming sector. The production of plastic gears for farm machinery branded Stagnoli Our company has always used its know-how to invest in new and innovative proposals to replace and/or integrate plastic materials with metal ones and to obtain items with a considerably lower specific weight, with an exponentially reduced environmental impact compared to the same part in metal, allowing high production standards to be reached in the face of a considerably reduced environmental impact, given by less CO2 emissions. --- The Metal Replacement activity, that is the use of technopolymers instead of traditional metal materials for the manufacturing of high performance gears, is the main feature of our core business. We have a vast range of technopolymer racks proposed by our company, designed to meet all the needs of the industrial, residential and mechanical sectors in general. We have always had the main objective of expanding our range of catalogue items, to offer all our clients the possibility of having a turnkey solution as immediate and reliable as possible for their applications. For this reason, we recently added a precision rack with helical teeth in technopolymer to the catalogue; specifically, it is a rack with the following geometric parameters: 500 mm long Module 2 Inclination angle of the helix 20° Pressure angle 20° Obviously, it can be supplied with the helical gears in technopolymer with 20, 30, 32 or 40 teeth according to specific requirements. --- Injection moulding is an industrial production process whose molten plastic material (plasticized) is injected at high pressure inside a closed mould, which is opened after the manufactured part has solidified. It is a complex process involving simultaneous thermodynamic, fluid dynamic and mechanical phenomena. Managing to anticipate what will happen during moulding, what the plastic gear will be like and prevent any deformations or other types of faults is essential. The key phase is therefore design. --- Home automation is the science that deals with all computerised and electronic applications in the home. It is increasingly diffused in residential complexes, especially new constructions and renovations. Thanks to automation, windows, sliding and rotating doors, curtains, shutters and gates can be controlled, opened, closed or adjusted using electronic control systems and electric actuators, often called motors for windows designed for automatic opening and closure of door and window fixtures in residential areas. --- The design of moulds and components in plastic is a complex business where taking into consideration the different technical, aesthetic, dimensional and economic requirements is fundamental, especially during the engineering phase. In designing a part in injected moulded technopolymer, other than the functional and structural nature, an important role lies in the issues linked to the transformation process: the way in which cast polymer enters the cavity, filling it and cooling to take the shape of the plastic part. --- Stagnoli constantly invests in improving its products, performance and quality of its services, including the expansion of its machinery park in its Lonato del Garda plant. This is represented by the recent insertion of hydraulic injection presses mainly dedicated to moulding its plastic gears and, specifically, micro-gears, whose market demand is ever-increasing. --- NVH (Noise Vibrations Harshness) is gaining increasing importance, especially for gears working in sensitive environments such as measurement equipment or actuators in vehicles, where passenger comfort is priority. --- “What would you do if you had to increase the transmitted power between the rotating shaft and the technopolymer transmission part? ”. This is one of the questions we are often asked and for which Stagnoli has a performing solution reproduced in the co-moulded keyless locking devices with our gears. --- Stagnoli is a leader in the design and manufacture of transmission elements, gears and gearboxes entirely made of technopolymer. The experience and know-how acquired in over thirty years of design and manufacture of the latter mean the company is considered an innovative partner for important, international projects in the metal replacement sector. --- The request for more performing solutions intensity Stagnoli's metal replacement business in many sectors such as Automotive, Medical and Aerospace. Currently, for example, approx. 16% of the weight of a vehicle is attributable to plastic components and it is forecast that in the next five years this percentage will increase to at least 25%. --- Movement starts from the mind and is then transformed into innovative, highly technological solutions: this is the leitmotiv that has distinguished Stagnoli for years, a leader in the design and production of plastic gears for the automotive sector. --- Our story begins in the early Eighties with a brilliant idea of the founder: injection moulding of technopolymer transmission elements. The desire for growth, which has always characterised our company, has led us towards the study and production of high-performance, resistant and quality mechanical gears in plastic , currently used in hundreds of thousands of applications. --- The experience and know-how acquired in over thirty years designing and manufacturing plastic gears, polymer transmission parts and other mechanical solutions have allowed our company to be considered an innovative partner for important international metal replacement projects. --- Almost forty years after the company's foundation, today it is possible to confirm it with data: Stagnoli's decision to use PA6 + 30%GF for the moulding of gears and transmission parts has proven to be a winning one. Confirmation has come from two key areas for the company's success: market and research&innovation. --- In recent times, the growing search for increasingly high performance in applications involving metal replacement has led to an exponential development of new plastics. --- For a number of years now the goal in the Automotive sector has been that of improving vehicle performance and reducing consumption, as well as decreasing CO2 emissions into the atmosphere. The strategy undertaken over the years has been to make vehicles lighter by focusing on the materials used to create them. Up to now the trend has been to use aluminium owing to its mechanical and physical characteristics, its recyclability and eco-sustainability, and its relative affordability compared to other metals. --- Stagnoli's commitment to finding ever more performing solutions translates this year into the introduction of a new service tailored to our customers. The new service is the 3D prototyping of technopolymer gears and mechanical components. --- The history of Stagnoli begins in the early 1980s with injection moulding. The innovative streak and the desire for growth, which have always characterised our company, have led us towards the study and production of high performance, resistant and quality mechanical plastic gears. --- In the early 1980s, Stagnoli consolidated the design and production of technopolymer gears and micro gears. After 40 years of study, experimentation and research, Stagnoli offers a vast and performing range of plastic gears, even of very small dimensions, with maximum precision and Made in Italy quality. --- Stagnoli's product range is vast and well-organised: in our catalogue (downloadable here) you can find a clear and complete overview of technopolymer components, precision gears and transmission parts. In just under 50 pages we have managed to condense our way of working and the results of our commitment to always provide the customer with the very best solution for silent, light, self-lubricating and high-performance plastic gears. --- Ten years ago, most gear manufacturers didn't even consider plastic as an option, especially in high power applications. The huge step forward in the search for technopolymers aimed at different applications and the clear advantages provided by plastic gears compared to metal ones has led to a reversal of the trend in the choice of material to produce gears. The advantages are numerous, but what we focus on in this news is that of the noiselessness of the plastic gears. --- The use of precision plastic gears is increasing every day, and in various applications both resistance and, safe and silent operation are often required. Metal replacement activity guarantees the answer to both needs. Thanks to Stagnoli's innovative proposal of helical tooth plastic gears, the performances related to reduced noise and smooth performance are amplified. --- Stagnoli offers a wide range of racks for sliding gates that are designed to meet all needs in the industrial and residential automation sector. Stagnoli's commitment to researching innovative solutions has now made it possible to benefit from the advantages of plastic materials for mechanical applications capable of guaranteeing quality and performance. --- Stagnoli designs and manufactures all its plastic components and precision gears in the Lonato del Garda plant, in the province of Brescia. A Made in Italy production that applies to thermoplastic moulding all the technology our customers need. Not just a supplier of technopolymer transmission parts, but a partner who actively participates, starting from the design phase up to the optimisation of the production of the customer. --- We are managing this difficult moment by immediately equipping our operators in production with all the PPE necessary to safeguard their health and by adopting all the safety measures as required by the circular of the Ministry of Health. We have activated smart working in order to limit our movements as much as possible while always remaining at the service of our Customers. This situation is a real challenge for all of us, but we know that only by being responsible and respectful of each other will we get through this moment. Together. #prevenire #unitisipuò #stagnoli --- Stagnoli confirms its international presence as a qualified and professional company producing and offering high-quality technopolymer gears and components, and at the same time contributing to industry magazines. One of the latest publications concerns durability tests on plastic gears which appeared in the December issue of Gear Solutions. An international magazine issued each month, in print and digital form, Gear Solutions aims to be the most reliable resource for those who want to keep up-to-date with what is happening on the subject of gears. --- Stagnoli designs and manufactures components, precision gears and transmission parts by taking advantage of the characteristics and high performance of thermoplastic materials, such as PEEK, PA46, PA12, PAEK, PA6+30%FV, POM and many others. Our company can count on over thirty years of experience in the transformation of these materials, both in their non-reinforced versions and with carbon fibre or glass reinforcement, with self-lubricating additives (PTFE, silicones, etc. ) and with stabilising or flame retardant reinforcements. We have an extensive catalogue of products, such as components, precision gears and transmission parts that we manufacture entirely in our factory in Lonato del Garda, in the province of Brescia. --- Stagnoli has been operating for forty years in the technopolymer gear sector, offering a wide range of standard and customised products. In fact, we are able to customise the products in the catalogue, following the specific needs of each customer. Among the items offered by us there are also the plastic bevel gears, made with high quality technopolymers, suitable for various applications and also suitable for contact with food (FDA approved). In detail, we offer straight bevel gears for the market and/or custom-design and custom helical bevel gears thus satisfying the most varied needs. --- Our company has been active since 1981 and since 1983 has been using technopolymers to make precision gears that find wide application in multiple industrial sectors. We use a large fleet of machines for moulding thermoplastic materials which allows us to manufacture and print more than 10 million gears with a weight ranging from 0. 1 grams to 1. 5 kilograms. All our precision gears meet certain characteristics, such as: High quality. Clean contact surface. Minimum runout in the rotating system. Stable locking. Maximum precision to guarantee the stability of the machine. How do we process technopolymers? And what precision gears do we make? Continue reading our in-depth article to find out more. --- The Metal Replacement activity, that is the use of technopolymers instead of traditional metal materials for the manufacturing of high performance gears, is the main feature of our core business. We have always set ourselves the goal of expanding our range of catalogue items to offer our clients the possibility of having a turnkey solution that is as immediate and reliable as possible for their applications. An example of this type are the technopolymer toothed pulleys, which in the past we offered at 5M and 8M pitch and, in the last few months, we also offer the aluminium insert. --- Thermoplastic materials such as technopolymers and hyperpolymers represent an important technological evolution within the mechanical sector. In fact, these are plastic parts that find application in the most different fields, which are capable of withstanding continuous use at high temperatures, but also offer good dimensional stability and excellent resistance to chemical aggression. For over thirty-five years Stagnoli have used various types of technopolymers and hyperpolymers to make precision gears. But what are the advantages of plastic gears? And why prefer them to the more traditional metallic models? In this news we have decided to list all the opportunities that these technical details are able to offer. Find out why technopolymers are a winning technology and what advantages they can guarantee. --- The sector of application of plastic gears has grown significantly in the last decade. However, the lack of ISO, DIN or AGMA standards for the analysis of the resistance of technopolymer gears has provided uncertainty on the design methodology; this meant that, for years, the only accepted method for gear design was the German guideline VDI 2545. However, a new directive for the design of thermoplastic gears was introduced in 2014. This is VDI 2736 Directive, which outlines a broader guideline consisting of 4 parts: The first part is available as a draft and covers general recommendations and material properties. The second and third parts are published in the final version and contain methods for evaluating the resistance of spur gears (second part) and helical gears (third part). The fourth part defines the measurement and evaluation of the material properties necessary for the resistance analysis. The greatest difficulty for the design of plastic gears is the lack of data: the quantity of variables to be taken into consideration, in fact, is very wide. Not only: these variables increase if we consider the different behaviour of the various types of technopolymer families. --- Technopolymer mechanical components are being used more and more and achieving greater success in various sectors, thanks to their innovative properties and the advantages they are able to offer. With its skill and professionalism, Stagnoli has committed to using technopolymers instead of aluminium or other alloys, offering its customers products in line with needs and able to offer high levels of performance. What are these plastic materials? And what advantages are technopolymer mechanical componentsable to offer? We have decided to clarify and examine this topic in more depth in this article. --- A few weeks ago, more precisely from 26 to 28 November, we took part in SPS Smart Production Solutions 2019 in Nuremberg, the parent event of SPS Italia, an unmissable appointment with intelligent, digital and flexible industry. The event was an important meeting place and direct comparison for the international manufacturing industry. The following is a post-show report. --- Electric motors are broadly utilised in a range of applicative sectors. The list is almost endless—watches, automobiles, vacuum cleaners, hair dryers and most everyday household appliances. They are often coupled with gearboxes containing plastic gears. Our company specialises in the design and production of such components, offering our customers a broad range of gears whilst guaranteeing the utmost quality and high efficiency in the application. Discover what electric motors are, how they operate and the application for plastic gears. --- Ever attentive to innovation and actively engaged in continuous renewal, Stagnoli will take part in the 2019 SPS exhibition in Nuremberg, the mother event of SPS Italia, the annual event established in 2011 for intelligent, digital and flexible industries, promoting direct discourse on the most challenging issues of tomorrow’s industry and a landmark of great importance for the Italian manufacturing sector. The 2019 SPS exhibition in Nuremberg will be held from 26th to 28th November, during which time the leading automation and digital companies from around the world will gather. The exhibitors present will represent the entire gamut of industrial automation, from simple sensors to cloud. --- For us, quality is an indispensable and strategic factor that allows us to competitively position ourselves and stand out in the market. For this reason, we constantly invest in improving ourselves and guaranteeing our customers services and products in line with the required quality standards. We are equipped with a Quality Management System (QMS), meaning we are a certified gear moulding company. In fact, we have been ISO9001-certified since 2016, in line with the international quality standard. Precisely how does our certified company print gears? Find out in this article. --- Today, we take you on an exploration of the production department that is less well-known than our moulding division but certainly of no less importance. It is the department that deals with CNC machining on our technopolymer transmission parts. We decided to let you know about its function and its advantages for your business: Find out more. --- Our company has established itself for some time in the field of glass processing machines. Our technopolymer gears are widely used in this sector: they are chosen and used, and thanks to the high performance, they are able to eliminate the risk of incurring the typical technical problems in terms of transmission components made of traditional materials. Companies that have adopted our technopolymer gears for glass processing have many benefits regarding profit and production. Some of these will be present at Vitrum, the International Exhibition dedicated to machines, equipment and systems for processing flat glass, cable and processed products. . The appointment is from 1 to 4 October at Fiera Milano Rho. --- The increasingly urgent demand for precision in the injection molded transmission parts leads to the optimization of all the variables involved in the entire process chain. The choice of the type of press receives full credit. Responding to these needs, we recently introduced full-electric presses in our fleet, which are gradually replacing hydraulic or hybrid models. This is due to the same advantages they offer and which concern: Greater precision in processing; A decrease in process cycle times; The greatest energy savings. Stagnoli innovates and updates itself with the new full-electric TOSHIBA EC75SX press, the latest generation machinery used in different areas, including the construction of transmission parts. --- The eighth edition of the International Gear Conference, Gears 2019 will be held in Garching (Monaco), at the Gear Research Center (FZG), September 8-20, 2019. The conference supported by national and international associations, gathers industry and academic community leaders, as well as experts in the gear and transmission field. The objective of Gears 2019 is to offer opportunities to discuss and reflect on the latest developments and research results in the field of transmission parts. The third edition of the International Conference on high-properties plastic gears will take place at the same time, focusing on providing answers to questions such as: Plastic gears: a possible alternative to steel gears? What are the current methods for simulating and calculating plastic gears? How can the durability of plastic gears be improved? How does the use of plastic gears improve NVH (Noise Vibration Harshness)? --- Recently, the growing search for increasingly high performance in applications involving metal replacement has led to an exponential development of new plastic materials. Given the intrinsic nature of the material, the technopolymers frequently fail to satisfy and/or guarantee the required properties. It is therefore necessary to consider the use of a superior class of polymers, called superpolymers (PEEK, PEK, PPS), which imply higher and often non-competitive costs. Stagnoli, always active in the research of materials, has certified the quality of polyamide PA4. 6, bridging the gap between conventional engineered plastics such as PA6, PA66, PBT, and special materials such as PPS and PEEK. --- The Automotive sector is constantly evolving with a clear objective: to improve and lighten the vehicle. The overall weight of the vehicle is increasingly being modified, replacing metal components with plastic parts and gears, while paying particular attention to aerodynamics; the aim is also to improve grip, especially on high-performance sports cars, with "moving parts" called "active spoilers", i. e. with aerodynamic devices that engage and/or change shape and/or incline according to the speed being sustained. These "active moving parts" are normally placed on the rear of the vehicle and are called "spoilers", but they can also be placed on other parts of the bodywork or the bottom of the bodywork, in this case taking the name of "diffusers" or "deflectors". These are also useful in an emergency, when violent braking is required while driving at high speeds. --- Technological development and the most modern trends are increasingly directed towards reducing the size of mechanical, optical and electronic devices. We responded instantly in order to follow the progress and the needs of the market, by thinking big but designing small. Our challenge: the design of mini molds... Technological development and the most modern trends are increasingly directed towards reducing the size of mechanical, optical and electronic devices. We responded instantly in order to follow the progress and the needs of the market, by thinking big but designing small. Our challenge: the design of mini molds. For the past six months, with the purchase of a mini press, our technical department has dealt with a new test and has immersed itself in the world of technopolymer mini gears and, more generally, of plastic mini components. --- For the first time this year, we will be present at Subcontratación 2019, the international subcontracting exhibition to be held from 4th to 6th of June 2019 in Bilbao.

For the first time this year, we will be present at Subcontratación 2019, the international subcontracting exhibition to be held from 4th to 6th of June 2019 in Bilbao. Subcontratación exhibition area will be divided between companies operating in production processes, such as castings, cuts, molds, dies and die-casting and companies that mainly work on machinery and equipment for casting, forging, surface treatment, welding, iron and steel. Our company fits perfectly in this context, In Bilbao we will therefore present our innovations and the latest applications relating to new projects. You will find us at stand N66 in Booth 5. If you want to make an appointment or wish to receive an invitation, contact us! For more information on the exhibition, visit the website: subcontratacion. bilbaoexhibitioncentre. com/en/ --- The speed reducer is a mechanical system usually consisting of a series of gears, whose function is... The technopolymer cascade reducer meets the modern requirements of silence and lightness The speed reducer is a mechanical system usually consisting of a series of gears, whose function is to transmit the rotary motion from an input shaft (called fast shaft) to an output shaft (called slow shaft) by reducing the number of revolutions and therefore the rotation speed. The reducers serve as means of coupling between motors and operating machines, in all those cases in which, having the two machines running at different speeds, it is not possible to use a direct coupling. Speed reducers are used in the design of: conveyor belts, medical machines, food processors, printing devices, vehicles, construction machines. The cascade reducers with technopolymer gears are among the most requested as they meet the increasing need for silent and light systems. Our company fits perfectly in this context, as leader in the design and production not only of technopolymer gears, but of everything linked to the world of plastic. --- The activity of Metal Replacement, applied to gears, transmission parts and also to other mechanical solutions, has allowed our company to be considered an innovative partner for important international projects. This is why our constant goal was to expand our range of items in the catalog. The new technopolymer toothed pulleys with HTD profile A real example was that of the technopolymer toothed pulleys with HTD profile with 5M and 8M pitch suitable for a belt width of 9, 15, 20 and 25 mm. The plastic material used is always a polyamide based technopolymer reinforced with glass fiber to offer strength and suitable mechanical features. The acronym HTD is the abbreviation of «High Torque Drive» and means: «High Torque Transmission». --- MOCA - Materials and Objects in Contact with Foodstuffs – are all the materials and objects that are intended to come into contact, directly or indirectly, with foodstuffs, according to a foreseeable use. MOCA regulation: materials and objects in contact with foodstuffs. Can thermoplastic gears and foodstuffs come into contact with one another while guaranteeing a high level of protection for human health? In order to answer this question it is necessary to be aware of the reference regulation and to understand the MOCA concept. MOCA - Materials and Objects in Contact with Foodstuffs – are all the materials and objects that are intended to come into contact, directly or indirectly, with foodstuffs, according to a foreseeable use. Here are some simple examples: - food packaging; - all household and related products (pans, plates, cutlery, glasses); - hygienic protection devices (e. g. work clothes for Food industry, butcher gloves, etc. ); - machines and equipment for processing and distribution (coffee machines, plant production lines, etc. ); - wood; - paper and cardboard (e. g. cardboard for pizza); - polymer granules intended for manufacturing MOCA. The MOCA regulation: all the news. In order to guarantee the safety of materials in contact with foodstuffs and protect the health of final consumers, MOCA is governed by European regulations, that must be followed by all manufacturers, integrated with the national legislation of each Member State if there are no specific EU standards: Regulation (EC) no. 1935/2004, known as the framework regulation, which provides the basic principles of material compliance and aims to guarantee the effective functioning of the internal market with regard to the inclusion of MOCA on the EU market. Regulation (EC) no. 2023/2006 which establishes the rules relating to the good manufacturing practices (GMP) of MOCA and applies to all sectors and to all stages of production, processing and distribution of these objects. Regulation (EU) no. 10/2011 (also called "PIM Regulation" Plastic Implementation Measure) which defines specific standards (migration limits, declaration of conformity, list of authorized substances) for plastic materials and objects intended to come into contact with food products. Legislative Decree 29/2017 that governs the sanctions (ranging from a minimum of € 1. 500 to a maximum of € 80. 000 for the violation of MOCA regulation provisions).     --- For the past 15 years our company is constantly looking for improvements and innovations in order to offer its customers various solutions according to their needs. The flagship of our range of products is the production of CFRP gears and components, abbreviation that indicates the gears and components produced with carbon-fiber-reinforced composite materials... CFRP: carbon-fiber-reinforced plastic materials For the past 15 years our company is constantly looking for improvements and innovations in order to offer its customers various solutions according to their needs. The flagship of our range of products is the production of CFRP gears and components, abbreviation that indicates the gears and components produced with carbon-fiber-reinforced composite materials. Today, in the mechanical engineering sector, metals are replaced with plastic composite materials as these are able to offer practical solutions where traditional materials fail. In fact, the production of CFRP gears allows solving problems related to the operation of the machines both at a thermal and mechanical level, with significant savings in terms of weight. The properties of cfrp gears and components The properties of carbon fibers make the carbon-fiber-reinforced composite materials ideal for many applications. In fact these fibers not only have a low weight, but at the same time have a high modulus of elasticity and low thermal expansion thanks to their composition. --- In order to meet the ever increasing requests of our customers, we have decided to fit our production department with a new 10-ton mini-press designed for the production and molding of thermoplastic micro-gears with a minimum weight of 0. 01gr and a maximum weight of 15gr. The extreme precision of the press guarantees higher molding quality and an advanced process control without the risk of degrading the technopolymer in the chamber. These features allow us to use a press dedicated to those products that would force us to make 8/16 moldings using a traditional presses due to their low weight, being notoriously more expensive and less controllable during the process. Megatech Mini-Press is built entirely in Italy and is connected to our MES system which facilitates us a remote control of the main machine parameters. All types of molds have been made within the company with underwater or hot-chamber injection for polyamide and POM gears and also for advanced technopolymers such as PA46 and PEEK. --- The ability to reinvent itself and always be in line with the market needs, be they technological or regulatory, is the prerogative of every large company. This is why we have added to our Stagnoli catalog a new line of gears designed for the food sector. These are spur gears and bevel gears, made of an innovative blue technopolymer, a polyamide-based polymer reinforced with glass fiber. This FDA-certified material has been specifically designed for the food industry using plastics and blue technopolymers; thanks to their high visibility, they are easily identifiable in case they accidentally end up inside a food product. To understand the importance of this innovation, it is enough to know that many companies have spectrograms on their production lines for the identification of specific color objects. --- Due to the ongoing climate changes, more and more Nations are starting to worry about pollution facilitating the spreading of electric bicycles in many European cities, a market in which we collaborate with some of the biggest E-bike engine manufacturers, producing technopolymer transmission and gears. According to ANCMA data, the National Association of Bicycles, Motorcycles and Accessories, in 2016 there was a 121,3% increase in the sales of electric bicycles in Italy compared to 2015, bringing Pedelec (pedal electric bike), marketed in our Country, to 124. 400 pieces sold. This trend is not limited to Italy: E-Bikes are becoming increasingly popular all over the world. Cheaper than electric cars, they do not require special infrastructures for their power supply and always guarantee the pleasure of riding a bike. And this is not just theory: the change has already begun, as being proved by the many companies that are investing in the sector. --- The use of technopolymers in gear manufacturing has been the core business of Stagnoli for over 30 years, a leading company in the sector and one of the first to include this technology into its products. Thanks to the in-depth research, Stagnoli was able, through practical tests carried out by the research-development department, to calculate, by means of advanced software (kissSoft/Fem), the indicative data of the torques transmitted by the technopolymer transmission parts. --- --- ## Catalogo Our spur gears are made with standard teeth (UNI6587/DIN3972) compatible with regular standard gears available on the market. They are suitable to be used both in pairs with another Stagnoli gear, or with a steel gear, and they don’t require lubricant. They are normally supplied with a rough hole, but for minimum quantities we supply the finished custom-designed piece by means of CNC turning (holes, keys, grains, etc. ). --- Our bevel gears are made with standard teeth, suitable for use with either a second Stagnoli wheel or a steel one and, like all our products, they do not need lubricant. They are regularly supplied with a rough hole, but for minimum quantities, we supply the finished custom-designed piece by means of CNC turning (holes, keys, grains etc). --- Our chain-stretcher pinions are made by co-molding a bearing in the technopolymer (Polyamide filled with glass fiber). They are often used as substitute for stainless steel pinions, in aggressive or humid environments, and in many other applications (from agriculture, to packaging machines) in which they also remarkably reduce noise (compared to metal pinions); the pinions are available in various numbers of teeth and pitches (1/2, 5/8 etc). If you do not find the chain-stretcher pinion suitable for your application, or you need co-molded stainless steel bearings, do not hesitate to contact us and submit your design; we will evaluate the best way to make it. --- Our pinions for roller chains (according to DIN8187/8188) are made of polyamide based technopolymer filled with glass fiber and they are ideal to use in aggressive, damp or sand/dust contact environments. Precisely for this quality, many companies in different sectors have replaced the steel pinions of their machines with Stagnoli pinions, considerably lightening them and reducing the noise and the need for greasing. They are available in various numbers of teeth and pitches (1/2, 5/8 etc). They are normally supplied with a rough hole, but for minimum quantities we supply the finished custom-designed piece through CNC turning (holes, keys, grains, etc. ) --- Our pulleys are made of polyamide based technopolymer (or PC) filled with glass fiber, with standard teeth, available with various profiles (HTD, T, AT XL etc). Our pulleys reduce noise, and the weight of the transmission; they can have a second ultrasonic welded flange and possibly a metal insert in case of high torques. They are used in Packaging and bottling lines in CNC machines and in many other applications (pasta processing, cleaning machines, CCTV, etc. ). They are available in various numbers of teeth and pitches. They are normally supplied with a rough hole, but for minimum quantities we supply the finished custom-designed piece through CNC turning (holes, keys, grains, etc. ). --- Our Belt Tensioner Pulleys are made by co-molding a bearing in the technopolymer (Polyamide filled with glass fiber). They are often used as substitute for stainless steel pulleys, in aggressive or humid environments, and in many other applications (from agriculture, to packaging machines) in which they also remarkably reduce noise (compared to metal pulleys). They are available in various sizes and profiles. If you do not find the pulley suitable for your application, or you need co-molded stainless steel bearings, do not hesitate to contact us and submit your design; we will evaluate the best way to make it for you! --- Our range of joints, male and female, consists of 3 models of different sizes, all 3 with aluminum insert to increase the transmissible torque. In our catalog you can also find the ferrule joint, which can also be coupled with steel male joints available on the market. Our oscillating joints and ferrules are molded by injection with a special additivated technopolymer with a small percentage of self-lubricating. The male/female joints are co-molded with an aluminum insert, and are supplied with a tolerated hole (which can then be enlarged), while our ferrules are compatible with the metal males currently available on the market. If you do not find the joint suitable for your application, or you need more information, do not hesitate to contact us and submit your design; we will evaluate the best way to make it for you! --- In our catalog you can find 2 types of planetary reducers completely made of technopolymer (except for the central pinion), available in module 1 and 1. 5. --- The racks have always been our flagship product and this lead us to a wide range, with different modules, lengths and construction methods. Our range of racks is very wide, we have racks with and without steel core co-molded in many modules and lengths. We only use high quality polyamide-based technopolymer, with very high mechanical properties. Our racks can work without lubrication, reducing weights and noise in the applications where they are used. The Stagnoli racks, indicated with the "precision" flag, are suitable for applications where, due to machine positioning and operation, the high precision on the tooth pitch is required. They are used in CNC machines, centralized warehouses, and many other applications. If you do not find the rack suitable for your application, submit a drawing or a request, we can process by CNC one of our catalog racks or make them custom-designed --- ---
