ABSTRACT:
A compound mold or tooling system is designed to provide an alternative to conventional, expensive, metal molds for various plastics molding applications. The compound mold comprises a replaceable thin-walled liner, or skin-mold, defining the mold surface, temporarily bonded by vacuum means or mechanical means to a conforming backing-mold mold body supported by a rigid backing-plate. Both skin- and backing-molds are composed of suitable polymers with or without additives, fillers, reinforcements or other inclusions depending on mold requirements. The backing-plate contains standard features and fixtures common to all molds used in the particular process or of a particular geometry.
