Abstract

The method of the present invention is particularly suited for making decorative objects in a mold cavity. The method enables one to form a decorative component having an outer elastomeric layer that is integral with an inner layer of foam. Because the chemical formulation for the outer layer and the inner layer is identical, other than the inner layer includes a foaming agent, the decorative component does not suffer from the drawbacks of the previous methods such as, for example, poor adhesion between the elastomeric layer and the foam layer causing delamination of the two layers, sinks or holes in the foam layer leading to imperfections in the elastomeric layer, and bleed through to the elastomeric layer from the foam layer. The method permits the mold to be pre-coated with an in-mold paint prior to the molding process. Coatings can also be applied after demolding the resulting part.
