Feedback

The two stage extruder consists of a first-stage twin screw extruder and a second-stage single screw extruder. The twin screw extruder realizes the shearing and mixing of materials and the single screw extruder completes the cooling and extrusion of materials. Two stage extruder has good cooling performance, can avoid material decomposition caused by overheating. Specially suitable for some heat and shearing sensitive materials processing.
