ABSTRACT:
An automotive door trim panel includes a carpet face panel that is electromagnetically welded to the lower portion of a thermoplastic substrate. The thermoplastic substrate is prepared by depositing metal particles on a bond surface of the thermoplastic substrate. Direct current is applied to the coil of an electromagnet disposed beneath the substrate to hold the metal particles on the bond surface. A molded-to-shape carpet face panel is then pressed against the mold surface while alternating current is applied to the coil of the electromagnet to electromagnetically weld the carpet face panel to the thermoplastic substrate.
