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.<\/p>\n
