ABSTRACT:
The molded shell of an article, while still warm from being molded, and while remaining within the mold or fixture in which it has been created, for instance by blow-molding of a parison of polyolefin plastic material into contact with the mold walls, is filled with a fluid, settable foaming plastic material, for instance polyurethane. This may be done by injecting the foaming mixture directly into the cavity of the shell. In this manner time, labor and materials are saved, and the resulting product is characterized by better adhesion of the foamed core to the internal wall surface of the shell.
