ABSTRACT:
A method of compression molding a special purpose coating or skin onto the surface of a freshly molded polymeric substrate, including the steps of: injecting a skin-forming material between the surface to be coated and the die forming that surface such that the substrate is hydraulically immobilized within the mold cavity during separation of the die from the substrate surface, and thereafter compression molding the skin-forming material over the surface.
