Sino-Alloy Machinery, Inc. would like to introduce our newest member to the PSM family of co-rotating, twin-screw compounding extruders! The PSM20B is a laboratory-sized extruder made with a special high-speed, high-torque gearbox. A larger motor than previous types, allows for an increased maximum screw speed of 1200 rpm and higher torque to handle engineering plastics.
