In-mold mating of substrate material to vinyl skin covering for the construction of two-component automotive interior trim parts

摘要

A method of molding automotive interior trim parts wherein a block of a predetermined thickness and area of a suitable grade of fiber or other suitable insert material is pressed into a molten vinyl shell during the latter's curing cycle. The fiber block or insert becomes fused to the vinyl shell and may expand to approximately three times its original thickness to serve as the backing and mounting insert for the finished two-component interior trim part.
