Profine GmbH in Troisdorf, Germany, is one of the largest window-profile makers in the world. It is producing main window-frame profiles at what is believed to be the highest output rate in the world—2600 lb/hr. Profine uses proprietary technology that cools the profiles internally with water. The high-output line, installed late last year, extrudes dual-strand coex profiles at 6 meters/min, using an Argos 135 parallel twin-screw extruder and two Konos 72 conical twin-screw coextruders from Cincinnati Extrusion in Austria (U.S. office in Erlanger, Ky.). The extruders’ new Polytherm screw geometry requires10% less torque. Profine built the high-output die. (859) 746-1530 • www.cet-us.com
