1. Introduction of Product

Model SJSZ series twin conical screw extruder is a kind of special equipment for extruding PVC power. With different sorts of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe material, profiled material, board material, sheet material, bar material and granulation. 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 screw with variable pitch and depth, so that the material can be more softly sheared and cut. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, temperature control tolerance can be±1℃.
