ABSTRACT:
The present invention relates to light weight molded plastic articles and methods of making same. More specifically, the present invention relates to a method of manufacturing a hollow-core, foamed-plastic, film-laminate article utilizing convention gas assisted molding apparatus with corresponding high production rate capabilities. The resulting film-laminate, hollow-core, foamed-plastic part comprises a class A show-face surface. The method comprises formation of a porous mass of molten plastic in the mold cavity containing the laminate. The molten plastic is cored out or hollowed by injection of gas into the mold cavity.
