The screw has applied oil cooling system. Barrel is cooled by special wind cooling system.The system has applied special computer control.According to customer’s requirements,most reasonable screw can be made so as to achieve best plasticity state and material quality.The screw is made by high precision special digital screw miller,extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screws with variable pitch and depth, so that the material can be more softly sheared and cut. The distibution bod is specially designed,pull force bearing is fully imported, the drive life span can be prolonged. It can bear larger extruding pressure.
