ABSTRACT:
A process and apparatus for the production of materials preplasticized to their final density from high molecular weight powder-form completed mixtures, which are directly used as starting product for subsequent final processing, wherein the powder mixture is conveyed along a helical compression screw and subjected to accelerated compression and, at the same time, preplasticized at a temperature which corresponds to the material temperature required for final processing.
