By combining a twin screw extruder in the first stage & a single screw extruder in the second stage, the functions of the extruder are divided into two units: kneading by twin-screw & extrusion by single-screw.

PCM Twin screw extruder
By keeping the head section open, the resin is prevented from getting hot burnt, & high mixing at low temperatures is achieved.

GS Single screw extruder
Single screw extruder with large diameter & short L/D to enable large-volume extrusion at low speed & low temperature.
