ABSTRACT:
A method for producing a multiplicity of miniature cavities extending from a mold surface for molding a plastic product having features 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. The mold may be in the form of a roll or belt for continuous processing, or in any form for discrete injection molding. The invention is particularly applicable to the production of touch fastener products, such as those with arrays of miniature hooks.
