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.

(EN) The invention concerns a method for producing a thermoplastic molding material or element, said material or element containing nanometric inorganic particles. In molten state, the thermoplastic is mixed with the nanometric inorganic particles and with a solubilizing agent in a conveyor screw extruder, the pressures and temperatures being adjusted so that the plastic is in melt form and the solubilizing agent in supercritical state. The invention is characterized in that at the output of the extruder, the mixture passes through a slot with a passage less than 20 $g(m)m to penetrate into an expansion zone and the molten material, wherein are incorporated the nanometric inorganic particles, is evacuated, reduced into molding material after cooling or transferred into a molding tool to be molded. The invention also concerns the molding material and the molding elements obtained by this method, as well as the uses thereof.
