发明名称 Method of containing foam during molding of foam-filled products
摘要 A mold assembly for molding vinyl skin shell-covered and foam-filled products, such as an automotive instrument panel, wherein waste portions of the shell and foam are eliminated from the molded product. This eliminates having to manually trim such portions from the finished product after molding. Specifically, compressible foam or silicone rubber gaskets or spacers of predetermined shaped, such as the shape of an opening suitable for a radio speaker, are placed in the mold and compressed between the mold lid and the bottom surface of the mold cavity.
