Abstract
In a method for producing a coated composite component, an injection-molded part is produced in a first cycle by introducing a melt into the cavity of a first mold. A polyurethane layer is then applied to the cavity surface of an open polyurethane mold half. The mold half with the injection molded part produced in the first cycle is associated with the polyurethane mold half, and the so formed second mold is closed. The polyurethane layer is pressed or embossed onto the injection-molded part in the second mold, and the coated injection-molded part is removed once the second mold has been opened.
Claims27
A method for producing a coated composite component, comprising the steps of:
- producing a thermoplastic plastic support by introducing a melt into a closed cavity of a first mold,
- opening the first mold, while leaving the produced thermoplastic plastic support in a mold half of the first mold,
- applying a polyurethane layer onto a cavity surface of a mold half of a polyurethane mold,
- associating the thermoplastic plastic support that was left in the mold half of the first mold with the mold half of the polyurethane mold that has the applied polyurethane layer,
- closing a second mold which includes both the mold half with the thermoplastic plastic support and the mold half with the polyurethane layer, thereby pressing or molding the applied polyurethane layer onto the thermoplastic plastic support and distributing the applied polyurethane layer over a surface of the thermoplastic plastic support in a region defined by a cavity of the second mold,
- at least partially curing the applied polyurethane layer,
- opening the second mold, and
- removing the coated composite component.
