During the mass production process of optical components, plastic injectedlens product is often the most suitable choice. Unit price of plastic pieces appears to be much lower than optical glass.
First step in the process of producing plastic components, the mold realization. If there is not much differences between PC and PMMA processing, molding allow a very high fidelity for complex shapes reproduction. Such as aspheric lenses.
This molding process is called molding-injection process and fit for the realization of any lens shape. This machine is composed of molding die that ensure a similar volume for all lenses produced, and a great reproductability.
