Method for selectively producing a first or a second variant of a multi-layer plastic component

Abstract

The invention relates to a method for selectively producing a first or a second variant of a multi-layer plastic component, wherein both variants have a carrier part (1), a decorative layer (2, 4, 5),and a foam layer (3) between the carrier part and the decorative layer, wherein the thickness of the decorative layer of the first variant is less than the thickness of the decorative layer of the second variant and the thickness of the foam layer of the first variant is greater than the thickness of the foam layer of the second variant, the foam layer is produced in a foaming tool, which has a first tool half, into which the carrier part is inserted before the foaming process. In order to produce the first variant, the decorative layer of the first variant is inserted into the second tool half of the foaming tool before the foaming process. In order to produce the second variant, a spacing layer (6) is inserted into the second tool half of the foaming tool before the foaming process, wherein, after the foaming process, the spacing layer is removed from the foam layer and the decorative layer of the second variant is applied to the foam layer. The foam layer (3) comprises at least onefirst section (3a) having a higher contour stability than a second section (3b).

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for the selective production of a first or second variant of a multilayer plastic component. Background technique [0002] Certain models of the BMW brand are offered in different dashboard variant designs, namely a basic variant (Basisvariante) and an optional variant (Sonderausstattungsvariante). What both variants have in common is their multilayer structure comprising a load-bearing part, a decorative layer and a foam layer in between. Figure 1a shows a basic variant, while Figure 1b An optional variant is shown, which has the same overall thickness D as the basic variant. like Figure 1a , 1b As can be seen from the illustration, the carrier part 1 of the basic variant is identical to that of the optional variant. exist Figure 1a In the basic variant of , there is a thinner decorative layer 2 made of plastic, which can be provided, for example, with a leather-like texture...

Problems solved by technology

because Figure 1b The foam layer 3 of the optional variant shown is less than Figure 1a Foam layer for the basic variant shown, thus requiring a separate tool / mold for each of the two variants, which entails high costs
