PCT No. PCT/EP89/01599 Sec. 371 Date Jun. 24, 1991 Sec. 102(e) Date Jun. 24, 1991 PCT Filed Dec. 22, 1989 PCT Pub. No. WO90/07412 PCT Pub. Date Jul. 12, 1990.In a process for the manufacture of thick, preferably sheet-shaped, thermoplastic molded parts or molded parts having areas of variable cross sections, at least one part of the plastic material is conveyed as a melt into a heatable and optionally coolable compression mold and is subsequently compressed. Plastic granules are mixed in with the melt before the melt is conveyed into a compression mold. A device to prepare such mixture of melt and plastic granules includes a first section designed as a melt extruder and a subsequent section designed as a mixing extruder. The granules can be fed into the melt between both extruder sections or into the second section.
