METHOD OF FABRICATING INJECTION MOLD INSERT FOR MOLDING LENS MOLD

摘要

PROBLEM TO BE SOLVED: To curtail the cost of an injection mold insert and to reduce the dispersion of the injection mold inserts which are replicated to be almost same. SOLUTION: The injection mold insert and a method of fabricating the injection mold insert for molding lens molds which provides a plurality of replicas of a single master mold mandrel to be produced, for example, by diamond point processing are provided. The mandrel is used to electroform an electroform mold insert component having an optical quality surface which forms the surface of an injection mold. An adhesive is used to fixedly attach the electroform mold insert to a separately machined mold insert substrate. COPYRIGHT: (C)2004,JPO
