20210078218 · 2021-03-18 ·

The present invention relates to a method for producing a composite part comprising a textured skin and a rigid or foam substrate layer, in particular a composite automotive trim part. The method comprises the steps of spraying or casting an aqueous thermoplastic dispersion onto a rigid or foam substrate composite followed by forming the composite into a composite part comprising a textured skin and a rigid or foam substrate layer. Preferably, the dispersion is derived from the extrusion melt blending of thermoplastic polymer, a dispersing agent, and water.

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

A method for selectively producing a first or a second variant of a multi-layer plastic component, where both variants have a substrate part, a decorative layer, and a foam layer between the substrate part and the decorative layer, includes producing the foam layer in a foaming mold which has a first mold half, into which the substrate part is inserted before the foaming process. To produce the first variant, the decorative layer is inserted into a second mold half of the foaming mold before the foaming process. To produce the second variant, a spacer layer is inserted into the second mold half before the foaming process where, after the foaming process, the spacer layer is removed from the foam layer and the decorative layer is applied to the foam layer. The foam layer includes at least one first portion having a higher contour stability than a second portion.
