Single-screw plastic extruders are mainly used to extrude soft and hard thermoplastics, such as polyvinyl chloride (PVC), polyethylene, etc. SJ series single-screw extruder is used in conjunction with related auxiliary machines (including molding heads) to produce a variety of plastic products, such as: films, pipes, bars, plates, threads, cable insulation, and hollow products. It can also be used for granulation and single screw extruder. It is the main extruder of the whole production line. It can be combined with various side extruders or machines to process various materials and produce different products, such as materials PS and PE. , PP, PVC, can be processed into pipes, rods, films, silk, cables, etc. The advantages of this machine are good plasticizing effect and stable extrusion work.
Application of single screw extruder:
A1: Pipe extrusion: suitable for PP-R pipe, PE gas pipe, PEX cross-linked pipe, aluminum-plastic composite pipe, ABS pipe, PVC pipe, HDPE silicon core pipe and various co-extruded composite pipes.
A2: Sheet and sheet extrusion: suitable for extrusion of PVC, PET, PS, PP, PC and other profiles and sheets. Extrusion of various other plastics such as wire, rod, etc.
A3: Extrusion of profiles: adjusting the speed of the extruder and changing the structure of the extrusion screw can be applied to the production of various plastic profiles such as PVC and polyolefins. Modified granulation: suitable for blending, modification and enhancement of various plastics.
Structural advantages of single screw extruder:
A1: The linear extrusion speed is fast, the production capacity is large, the power consumption is low, and the multi-layer co-extrusion of 1-5 layers can be realized.
A2: The copper bushing is more wear-resistant, prevents material leakage, and ensures the stable operation of the extruder.
A3: Spiral groove feeding, efficient transmission, effectively reducing the back pressure of the extruder.
A4: The unique design (blocking zone, shearing zone, mixing zone) ensures uniform plasticizing effect, reduces screw pressure, and ensures high-speed and stable output.
A5: The high-torque gearbox is exquisite in shape, compact in structure, low in noise, large in carrying capacity, and high in transmission efficiency, which can ensure long-term trouble-free operation;
A6: Die PCA (pipe air cooling system) greatly improves the extrusion speed, shortens the cooling length of the extrusion line, and improves the quality of the inner surface of the pipe;
A7: Intelligent PLC control system, user-friendly interface, simple and convenient operation;
