Harden Technologies Ltd. has developed SZS series co-rotating twin screw compounding extruders. We use our self-processed ‘Integrated Bimetallic Coat’ rather than traditional bimetallic barrels in the machines, which can achieve good performance with high torque, high-speed and high productivity.

Our own ‘Integrated Bimetallic Cylinder’ has the following advantages:

• Will not possess material
• The edge of the coat will not crack
• Have long operation life
