Abstract
A method for the manufacture of a component unit for heat exchanger, substance exchanger and/or bioreactor systems, with at least two walls joined together and composed of structured thermoplastic sheets, wherein a fused strip issuing from a melt shaping tool on the extruder head of an extruder is introduced, after passing through a precooling distance L, continuously into a strip molding press, and wherein the fused strip is continuously shaped in the strip molding press to form a structured plastic sheet and set by cooling. An apparatus for the practice of the method, wherein a melt shaping tool disposed on the extruder head, a continuously driven strip molding press, a system for the severing, stacking and/or winding and/or folding of the plastic sheets produced, and a cyclically operated bonding system are provided.
