Extruder Screw Cooling – R&B Plastics MachineryOct 08, 2014 · Screw cooling on the feed section core of the screw should always be installed. In most cases, screw cooling will be a benefit to the process. It will give the operator another “zone” of control of the extruder. The main theory of “solids conveying” is that the resin must “stick to the barrel” and “slip on the screw”. By cooling the root of the screw it will reduce the Coefficient of Friction between the steel …
