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.
