Method of fabricating an injection mould insert for contact lens moulds and injection mould insert

摘要

An injection mold insert and a method of fabricating an injection mold insert for molding lens molds which provides a plurality of replicates of a single master mold mandrel which may be produced, for example, by diamond point. The mandrel is used to electroform an electroform mold insert component having an optical quality surface which forms a surface of an injection mold. An adhesive is used to fixedly attach the electroform mold insert to a separately machined mold insert substrate.
