MOLD METHOD AND APPARATUS FOR PIN-STRIPE OR MATCHING COLOR PLASTIC SHELLS ABSTRACT OF THE DISCLOSURE Apparatus and a process for manufacturing pin-stripe or common color thin-walled hollow shells for parts such as automobile door panels, controls and instrument panels from dry thermo-plastic powders include a powder box divider to form two or more compartments in a powder 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 powder. The charge box and mold are joined and then are rotated so that the powder is distributed into each mold section by gravity flow. Thereafter a third powder is distributed against an exposed division surface on the mold separation edge so as to form a pin stripe or common color for bonding prior cast multi-colored sections of a resultant shell of cured material.
