Abstract

The present invention relates to a process for the production of coated mouldings, by injecting a moulding composition into an injection mould and cooling the composition to obtain a moulding, and altering the injection mould in such a way as to produce an intermediate space between a surface to be coated of the moulding and the inner surface of the injection mould, and using injection moulding to charge a reactive mixture to the resultant intermediate space, where the temperature of at least a portion of the injection mould is increased for the curing of the reactive mixture.The present invention moreover describes a system for the conduct of the process described above.
