Abstract

In a process for extruding polymer melts (25) to form hollow chamber sections (21) by pressing the polymer melt through a shaping tool (24) with an internal shaping mandrel (26) and by subsequently sizing and cooling the hollow chamber section strand in a sizing and cooling unit (31) it is provided for the sizing and cooling of the hollow chamber section strand to be carried out in the sizing and cooling unit under extrusion pressure. A device for carrying out this process is characterized in that shaping tool (24) and sizing and cooling unit (31) are rigidly connected to form a closed system so that the strand extrusion pressure prevailing in the shaping tool can be propagated into the sizing and cooling unit, and that the shaping mandrel (26) protrudes out of the shaping tool (24) into the sizing and cooling unit (31).
