Abstract
Abstract The subject matter of the present invention is a process for producing decorable moulded parts made of plastic materials, whereby an extrudable thermoplastic material is injected or pressed behind a non-dried or non-cured flat decorative layer or paint layer. In a preferred embodiment, the decorative layer or paint layer is powder coated, whereby the support film, the paint layer and the thermoplastic material are coextruded together. This process allows decorable moulded parts having complex geometrical shapes to be manufactured.

Claim 1
Independent Claim
190 words
Process for manufacturing decorable moulded parts comprising: extruding a decorative layer or paint layer composed of a thermoplastic-duroplastic material which is non-dried or non-cured with a separable support film to form a laminate; placing the laminate within a mould; injecting or pressing an extrudable thermoplastic material behind the decorative or paint layer of the laminate in the mould such that the support film, the decorative or paint layer, and the thermoplastic material are sandwiched together by heat and pressure within the mould to form a moulded part and such that the decorative or paint layer and the thermoplastic material are brought together with both in a molten state and with sufficient heat to cure the decorative or paint layer and cause melting of the two materials at their engagement to form a blending between the decorative or paint layer and the extrudable thermoplastic material, wherein the decorative layer or paint layer is cured in a temperature range of from 130 to 240° C. during 0.5 to 120 minutes; releasing the moulded part from the mould; and stripping the support film from the decorative or paint layer of the moulded part.
