Method for producing an interior trim for a motor vehicle, including a substrate and a coating having the appearance of wood

摘要

The invention relates to a method consisting in: inserting the coating (6) into a shaping and injection-molding mold (14); closing the mold (14) such that the coating (6) is shaped against a shaping surface (22) of the mold (14) as the mold (14) is closed; and, subsequently, overmolding the substrate (4) by injecting a plastic material into the mold (14). According to one aspect of the invention, the shaping surface (22) is induction-heated in order to thermoform the coating (6) as the mold (14) is closed, by generating induced currents that propagate along the shaping surface (22), and the induction heating is stopped in order to set the plastic material.

1. A method for producing an interior trim for a motor vehicle, interior trim including a plastic substrate and a decorative coating having a wood layer and covering the substrate, the method comprising the steps of:
inserting the coating into a shaping and injection-molding mold having a shaping surface, closing the mold so that the coating is shaped against the shaping surface due to the closing of the mold, with induction heating of the shaping surface as the mold is closed in order to thermoform the coating, the shaping surface being heated to a first temperature range, then overmolding the substrate onto the shaped coating by injecting a plastic material into the closed mold, while a cooling device keeps the mold within a second temperature range different from the first temperature range, the induction heating being stopped before or during the injection of the plastic in order to set the plastic material.
