ABSTRACT:
A method for manufacturing an automobile trim component includes the step of coextruding a plastic unfoamed material and foamed material into a multilayer parison, which is thereafter blow molded to a desired form. After the layers are cured, the article is removed from the blow mold and sectioned into multilayer skin halves, and one skin is placed in an injection mold. The core resin, either thermoplastic or thermoset in nature, is then injected into the injection mold and onto the skin, and then compresses the resin against the skin to produce a shell comprising a resin core layer, intermediate foam layer, and decorative outer layer.
