Abstract
A method for producing a multiplicity of fastener element molding cavities extending from a mold surface, for molding a plastic product having fastener elements integrally molded with and extending from a product base, and a mold so produced. The mold cavities are formed by depositing multiple layers of plating material on a workpiece in a predetermined pattern selected to produce a desired mold cavity shape, or by depositing a thick stratum of plating material over an array of fastener elements and then removing the fastener elements to leave shaped cavities within the plating material. The mold may be in the form of a roll or belt for continuous processing, or in any form for discrete injection molding. Molds having fastener element cavities defined by rigid cast materials are also disclosed.
