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.
A method of producing a mold surface defining an array of blind cavities extending therefrom, each cavity having a shape of a hook fastener element, for molding a corresponding array of hook fastener elements integrally with and extending from a fastener product base, the method comprising the steps of
A method of producing a multiplicity of hook fastener element-shaped blind cavities extending from a common surface of a workpiece for molding a plastic hook fastener product having a multiplicity of hook fastener elements integrally molded with and extending from a product base, the method comprising the step of depositing plating material on the common surface of the workpiece, in a predetermined pattern, to produce the multiplicity of hook fastener element-shaped blind cavities, the plating material forming a multiplicity of mold surfaces for molding corresponding surfaces of the multiple hook fastener elements.
A method of forming a mold surface defining an array of blind cavities extending therefrom, each cavity having a shape of a hook fastener element, for molding a corresponding array of hook fastener elements integrally with and extending from a hook fastener product base, the method comprising the steps of
