Abstract
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.
Claims15
A method for producing an interior trim for a motor vehicle, including a plastic substrate and a decorative coating having a wood layer and covering the substrate, of the type in which the coating is inserted into a shaping and injection-molding mold, the mold is closed so that the coating is shaped against a shaping surface of the mold due to the closing of the mold, then the substrate is overmolded by injecting a plastic material into the mold,
- characterized in that the shaping surface is induction-heated in order to thermoform the coating as the mold is closed, by generating induced currents that propagate along the shaping surface, and the induction heating is stopped in order to set the plastic material.
A method for producing an interior trim for a motor vehicle, comprising the steps of:
- inserting into an injection-molding mold a covering having a plurality of layers including at least one wood layer;
- closing the mold so that the covering is positioned against a shaping surface of the mold;
- shaping the covering using induction heating of the shaping surface;
- forming a substrate on a side of the covering opposite the shaping surface by injecting a plastic into the mold;
- and
- stopping the induction heating, thereby permitting cooling of the covering and substrate.
