Parallel twin screw

Introduction: Flat twin screw is a kind of high performance screw, suitable for processing and conveying polymer materials. Precision design, parallel (co-rotating and counter-rotating), meshing and non-meshing, they can be customized according to the machining requirements of kneading blocks, conveyor elements, reverse conveyor elements and gear mixing elements, thus showing excellent mixing capabilities and great process flexibility.
