Abstract

Procedure for producing molded synthetic plastic parts, providing a worm or worm screw extruder with a load and a thermosetting material and operating the machine to directly produce a solidified extruded or molded part, characterized in that: (a) the thermosetting material is mainly in the form of solid particles; (b) the filler and thermosetting material are provided in the form of an inhomogeneous mixture at the upstream end of the machine drum; and (c) the machine is operated to convert the non-homogeneous mixture into an intimate and homogeneous mixture in the drum.
