SJ Series Plastic Single Screw Extruder


Single screw plastic extruder: Based on years of design and manufacture experience, absorbing advanced technology from home and aboard, accepting customers opinion, we have developed Single Screw Extruder, select various structured Venting Type Single Screw Extruder (separated type, mixing type, barrier type and distribution type, as well as the combination of these types), the screw is applicable to extrude various kinds of materials such as PP, PE, HIPS, ABS, PMMA, PC, etc. The extruder is widely used to produce such products as: plastic board, sheet, hollowness grid board, cast film, water proof film, and plastic aluminum composite products.

Single screw extruder is widely used in the area of water supply gas supply, double resistance pipes and non-excavation. Feeding section is grooved structure with temperature controller, and easy to get high capacity and stable extrusion. With advanced BM screw structure, it is able to divide the HDPE material from solid to liquid .


Single screw extruder is a kind of special equipment for extruding of HDPE, PP,PPR, PPB . It is the main machine in HDPE/PP/PPR/PPB Pipe extrusion line. With different sorts of molds and auxiliary machines, it can produce all sorts of plastic pipe material, profiled material, plate material, sliced 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 of extruder 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 distribution box of single screw extruder 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 of single screw extruder 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.
