Latest Patents

Andreas Praller holds a patent for a "Process and device for cooling extruded hollow sections." This invention involves directing liquid or supercritical carbon dioxide into the interior of plastic hollow sections through an extruder head. The carbon dioxide is then depressurized in at least one depressurization nozzle, resulting in the production of carbon dioxide in both gaseous and solid forms. The gaseous carbon dioxide is directed to the inner wall of the hollow section, while carbon dioxide snow is introduced for heat exchange, ensuring that the inner wall remains undamaged.
