Besides our key counter-rotating twin screw PVC compounding extruder, Harden also developed SZS series co-rotating twin screw compounding extruder which is different from that of traditional twin screw extruder. We use our self-processed ‘Integrated Bimetallic Coat’ in the machine, which can achieve good mixing effect with high torque, high-speed and high productivity.
Comparing with traditional bimetallic barrels, our special ‘Integrated Bimetallic Coat’ has the following advantages:
- Will not possess material.
- The edge of the coat will not crack.
- Have long operation life.
