Model SJZ series conical twin screw extruder is a kind of special equipment for extruding PVC compound. With different kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material and granulation.

The conical twin screw have applied oil cooling system. Barrel is cooled by special wind cooling system. The conical twin screw extruder system has applied special computer control. According to customer's requirements, most reasonable strcuture of conical twin screw can be made so as to achieve best plasticity performance and material quality. The conical twin screw is made by high precision special digital screw miller, extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screwa with variable pitch and depth, so that the material can be more softly sheared and cut. The distribution bos is specially desighed, pull force bearing is fully imported, 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, there are few problems which can be easily eliminated. The cooling system has applied speacial design, heat emission area is enlarged, the cooling is rapid, temperature control tolerance can be ± 1degree.
