Plastic-metal compound body

摘要

The plastic-metal-composite body (1) comprises a metal decorative layer (2), a plastic layer as a carrier layer (3), which is connected with the decorative layer by an injection-, injection molding- or pressing process, and a decorating element. At a height of an edge portion of the metallic decorative layer, a recess is provided in the carrier layer in the form of a shrinkage bag, where the recess enables a relative movement between the decorative layer and the carrier layer during cooling to compensate different shrinkage behaviors of the decorative layer and the carrier layer. The plastic-metal-composite body (1) comprises a metal decorative layer (2), a plastic layer as a carrier layer (3), which is connected with the decorative layer by an injection-, injection molding- or pressing process, and a decorating element. At a height of an edge portion of the metallic decorative layer, a recess is provided in the carrier layer in the form of a shrinkage bag, where the recess enables a relative movement between the decorative layer and the carrier layer during cooling to compensate a different shrinkage behaviors of the decorative layer and the carrier layer during cooling after the production. The shrinkage bags are arranged, so that they expose a partial section of the edge portions of a front side of the decorative layer in the area of the larger shrinkage of the carrier layer. The dimensions of the remaining space (R) between the front side of the decorative layer and the carrier layer through the shrinkage bag are adapted to a shrinkage ratio of the decorative layer to the carrier layer. The shrinkage bag has a width, which corresponds to the half of the difference of the shrinkage paths traversed from the decorative layer and the carrier layer, where the shrinkage paths result from different linear expansion coefficients of the decorative layer and the carrier layer. Positioning lugs or positioning hooks are formed at the decorative layer and/or the carrier layer. The carrier layer is taperedly implemented with the carrier layer in a contact area and/or a covering area. The decorating element is insertable into the shrinkage bag, so that it partially covers the shrinkage bag. An independent claim is included for a method for producing a plastic-metal-composite body.
