Described is a method for producing rear-injected plastic moulded parts consisting of a decorative layer, a foam layer, and a substrate; each of which respectively consisting of polyolefins. According to the method, the decorative layer and the foam layer are inserted into an injection mould in the form of a composite, and are then rear-injected with the substrate material into the closed injection mould. In order to structure the outer surface of the decorative layer on the finished moulded part as desired, the inner surface of the injection mould, against which the decorative layer is applied, is structured in a complementary manner. A foam layer formed from closed cells is used, the layer being permanently compressed during the hardening of the substrate material in the closed injection mould according to the structuring of the surface of the injection mould. The structuring of the surface of the injection mould can be obtained by correspondingly shaping the surface itself or by inserts which are to be arranged between the surface of the injection mould and the decorative layer.
