METHOD FOR PRODUCING MOLDED OPTICAL PARTS

摘要

The invention relates to a method for producing an optical moulded body (2), in particular a lens element (2), comprising producing a pre-moulding (4) in a moulding tool by injection moulding of a first plastics material and producing at least one covering layer (6.1, 6.2) on the pre-moulding (4) by injection moulding of a second plastics material, wherein the temperature of the moulding tool for producing the pre-moulding (4) is from 30% to 60% lower than the temperature of the moulding tool for producing the at least one covering layer (6.1, 6.2).
