Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Further details and advantages of the present invention result from the following description of an embodiment in connection with the drawing, which illustrates in schematic side views the pro-duction of an embodiment in different stages, wherein:

[0019] FIG. 1 shows a longitudinal sectional view of the embodiment after a second decorative layer has been applied to a first decorative layer and

[0020] FIG. 2 shows a view according to FIG. 1 after the application of a rear reinforcement layer against the first decorative layer.

DETAILED DESCRIPTION OF THE INVENTION

[0021] FIG. 1 shows a cross-sectional view of a first decorative layer 1, which presently is formed as a metal foil with a thickness of between 0.05 and 0.3 mm, preferably 0.09 and 0.11 mm, in particular 0.1 mm. The first decorative layer was formed by cutting and calibrated to the said thickness, if necessary brought to measure or provided with supporting holes, in order to position and hold the first decorative layer 1 on pins of an injection mold. It may be possible to transform the first decorative layer 1 into a three-dimensional preform by applying pressure and temperature, for example to produce a slight contour on the visible side and/or a circumferential edge in the outer zones of the decorative layer 1. The first decorative layer 1 can also be sprayed with a stain or shot-blasted/surface-treated.

[0022] A second decorative layer 2 of a wood veneer is placed on top of this first decorative layer 1. The second decorative layer has a thickness of between 0.1 and 0.5 mm, preferably 0.22 and 0.28 mm, in particular 0.25 mm. Presently, the second decorative layer 2 has several separate island-shaped decorative elements 2a, 2b, and 2c which are each provided independently and without connection to each other. These individual decorative elements 2a, 2b, and 2c are each provided with a lamination on the back side facing the first decorative layer 1, via which the decorative elements 2a, 2b, and 2c are bonded to the first decorative layer 1. In this way, the intermediate product shown in FIG. 1 is prepared, placed in a mold half of an injection mold and positioned there. A visible side 3a of the first decorative layer 1 or 3b of the second decorative layer 2 abuts a surface of the injection mold limiting the cavity, whereas a back side 4, which is formed exclu-sively by the first decorative layer 1, is exposed to the mold cavity. A plastic component is now injected into the mold cavity which forms a reinforcement layer 5 on the back side 4 of the first decorative layer 1. By injection molding around a backside of the reinforcement layer 5, it is con-nected to the back side 4 of the first decorative layer.

[0023] The intermediate product shown in FIG. 1 is compressed due to the effective injection pressure and the holding pressure during solidification of the plastic component. The decorative elements 2a, 2b, and 2c of the second decorative layer 2 press into the first decorative layer 1, as shown in FIG. 2. In the embodiment shown, the decorative elements 2a, 2b, and 2c of the second decorative layer 2 are on one level with the visible surface 3 of the first decorative layer 1. By pressing the second decorative layer 2 into the first decorative layer 1, the first decorative layer is circumferentially formed around the surface elements of the second decorative layer. On the visible surface of the product shown in FIG. 2, the first decorative layer and the second decorative layer 1 are exposed. Thus, the surfaces of the wood veneer elements forming the second decorative layer 2 are also provided to be exposed on the surface of the decorative molded part.

[0024] The rear injection molding in the form of the reinforcement layer 5 can form or have functional elements for fastening the decorative molded part to a chassis of a motor vehicle.

[0025] Afterwards, the further intermediate product shown in FIG. 2 is usually converted in an indexing tool in order to apply a coating on the visible side 3a, 3b, presently by overmolding the visible side 3a, 3b with a transparent thermoplastic such as PMMA. This overmolding may lead to a further compression of the decoration formed from the first and second decorative layers 1 and 2, particularly, if the first decorative layer 1 is much softer than the second decorative layer 2.
