Cooling screw for foam extrusion

PF_PEA_TurboScrew.gif
The Turbo-Screw is said to increase throughput in plastic foam extrusion. The cooling screw has cross-flight holes that improve mixing and reduce energy use. The average throughput increase is said to be 42.5% on foam polystyrene sheet and 62.5% on foam polystyrene insulation plank and board. The screws process foamed polyolefins and polystyrene in long single-screw extruders, tandem machines, and twin-screw machines. Instead of selling screws, the company licenses its screw technology and users pay a ?use? fee each year. Users are located world-wide, with two new licensees added in Oct. 2005.
