ABSTRACT:
A method and apparatus for producing a molded article comprising covering at least a portion of the mold wall with a thin smooth surfaced soft lining as an integral permanent lower part of the mold cavity, thereafter loading a preformed grained vinyl shell against at least a portion of the soft lining; closing the mold and injecting a reactive plastic formulation into the mold such that the reactive plastic material forms a rigid backing layer that is strongly bonded to the vinyl shell without distorting the vinyl.
