Injection compression moulding process

Injection-compression moulding processes are low-pressure processes so that, for instance, decorative trim or metal inserts are protected. It is precisely in the case of light engineering applications that low injection and follow-up pressures minimize internal stresses and, thus, have a strong influence on the optical properties.
