Method of making a combination speaker grill and automative interior trim panel

A method of manufacturing a rear shelf trim and speaker grill panel ( ) for an automotive vehicle ( ) includes steps of punching a substrate layer ( ) of a polypropylene and flax material with a punch set ( ) to form a grill section ( ). The substrate is folded in half and placing a decorative carpet layer ( ) is placed over the folded substrate layers ( ). The two layers are blow molded together into a combined speaker grill and rear shelf trim panel ( ).

Method of making a combination speaker grill and automotive interior trim panel

A method of manufacturing a multi-layered plastic manifold ( ) including molding an outer layer ( ) of the manifold ( ) about a blow molded core insert ( ). The outer layer ( ) is molded by either a thermoplastic injection molding process or a urethane casting process. While the outer layer ( ) is being molded, the pressure and temperature within the core insert ( ) are controlled to preserve the structural integrity of the core insert ( ).

Multi-process molding method and article produced by same

A process for cutting hollow molded plastic parts uses two knife cuttings in sequence. A first knife blade (42) is pressed on an uncut hollow molded plastic part for cutting therethrough with a guillotine blade action to form an access hole (46, 48) in the plastic part (10). The plastic part (10) may be secured onto a clamp (34, 36) for the first guillotine blade action. An outer support clamp (50, 52) is then secured about the plastic part with an outer side of the support clamp being positioned in proximity to the finished cut edge (65) of a finished plastic part. A mandrel (54) is inserted into the access hole (46, 48) of the part. The inner end of the mandrel is axially spaced from the outer side of the support clamp to allow a thin knife blade therebetween. A thin knife blade (62, 64) then cuts off the rough edge (47) to provide a finished cut edge (65) in the plastic part axially interposed between the outer side of the support clamp and the inner mandrel.
