Embodiment Construction

[0035] figure 1 A schematic view of a plastic trim part (I) according to the prior art is shown. A polymer film (2) with a decorative print (4) is arranged on a section of a polymer carrier (1), for example a dashboard of a motor vehicle. The edge region ( 5 ) can be designed not only in the same color as the polymer carrier ( 1 ), but also in a different color.

[0036] figure 2 A schematic view of a plastic trim part (II) according to the invention is shown. A transparent polymer cover ( 3 ) of PC or PMMA is arranged on an opaque polymer carrier ( 1 ) of acrylonitrile-butadiene-styrene (ABS). A polymer film (2) with a decorative print (4) is arranged between the polymer carrier (1) and the polymer cover (3). The transparent polymeric cover (3) protects the polymeric film (2) from UV radiation, abrasion and damage and at the same time makes a decorative imprint (4) on the polymeric film (for example, Kremer Pigmente GmbH & Unlimited GmbH & Co. KG, Aichstetten, Germany, ...

Abstract

The invention relates to a method for producing a plastic trim part, wherein a. a polymer film (2) is laid in an injection die, wherein the polymer film (2) has an opaque or partially opaque imprint (4) or color pigmentation which is decomposition-stable at a temperature of at least 250 DEG C, b. the polymer film (2) is back-injected by a polymer carrier component (1) and c. a polymer cover component (3) is injected on the polymer film (2) and the polymer carrier component (1).

Description

technical field [0001] The invention includes a method for producing a plastic trim, a plastic trim and their use. Background technique [0002] With increasingly stringent regulations on the carbon dioxide emissions of motor vehicles, there is also a strong desire to reduce the weight of vehicles and thus their fuel consumption. Continuous further developments in the field of plastics have enabled the replacement of large parts of the metal bodywork by correspondingly lighter elements made of polymeric materials. Parts in particular or also the entire window area can be replaced by elements made of polymeric material. In many cases, they exhibit hardness, stability and load-bearing capacity comparable to those of vehicle windows made of steel, at a significantly lower weight. In addition, the center of gravity of the vehicle is shifted further downwards due to the weight reduction, which has a positive effect on driving performance. Furthermore, polymeric materials can b...
