Injection molding processes that affect the optical quality of plastic lenses

You are asking what are the injection molding processes that affect the optical quality of plastic lenses? Injection temperature and mold temperature.

1, injection temperature: injection temperature affects the molten state and fluidity of the plastic, which in turn affects the filling properties and shrinkage of the plastic.

2, mold temperature: mold temperature control for the optical quality of plastic lenses is critical, high mold temperature melting point of the early arrival from the lens surface of the thermal prick marks and uneven cooling.
