SJ series single-screw extruder design concept 
 ◎ on the basis of high-quality, high velocity extruding. 
 ◎ low-temperature plastics design concepts to ensure high quality product. 
 ◎ second order overall design, reinforcing plasticization to ensure the adjustment of high-performance extrusion. 
 ◎ special barrier, BM mixing designed to ensure that the mixing effect of the material. 
 ◎ high torque output, a large thrust bearing. 
 ◎ gear, shaft for high strength alloy steel, carburizing and tooth grinding. 
 ◎ high hardness, high-quality finish, ultra-low noise. 
 ◎ PLC intelligent control, the linkage between the main and auxiliary. 
 ◎ easy to monitor man-machine interface, easy understanding of the processing and machine status. 
 ◎ Control mode (temperature meter) can be replaced as needed. 
 ◎ Material 38CrMoAL / A nitrogen treatment, wear. 
 The ◎ strict temperature control accuracy of wind cooling and water cooling. 
 ◎ The unique design of the feed inlet, a water-cooling unit. 
 ◎ with groove surface feeding end of sleeve barrel, with enhanced feed function to provide a guarantee for the high velocity.
