Patent ID: 8178016

Claim:
A method for manufacturing a multilayered composite molded part in a pressing tool comprising a lower part and upper part, the composite molded part having a plurality of layers, a lower layer and an upper layer comprising particles provided with binder, wherein the layers surround a pre-pressed molded part which is inserted as a central layer, the inserted molded part having coarser particles than those of the lower and upper layers, the method comprising: for the lower layer, particles provided with the binder are poured into a mold in the lower part of the pressing tool; forming the upper layer; the pre-pressed molded part, which has coarser particles than those of the lower and upper layers, is inserted into the first layer; the layers are compressed together with the pre-pressed, inserted molded part under the influence of pressure and heat so as to form the multilayered composite molded part, via the inserted molded part corresponding to the lower layer by means of the upper part of the pressing tool which is guided onto the upper layer; wherein the particles for the lower and upper layer are poured into the mold or onto the inserted molded part by a movable screen.
