ABSTRACT:
Apparatus and a process for manufacturing multiple color thin walled hollow shells for parts such as automobile door panels, controls and instrument panels from thermoplastic plastisol includes a plastisol box divider to form two or more compartments in a plastisol charge box and means for joining the charge box divider end-to-end with a mold separation edge on an open-ended heated mold for separating the mold into two or more sections; each compartment of the charge box has a different color plastisol. The charge box and mold are joined and then are rotated so that the plastisol is distributed into each mold section by gravity flow with the plastisol from each section flowing to the divider which separates the colors so as to form two or more tones on a resultant shell of cured material.
