SJ series new high-efficiency single screw extruder
SJ series new high-efficiency single screw extruder
1. Regarding the single screw extruder
The SJ series new high-efficiency single screw extruder is suitable for processing various polyolefin plastics, such as PE, PP, PPR, PB, PS, PC, ABS, PMMA, etc., to produce corresponding plastic pipes, sheets, plates, profiles and other products. According to different processing materials, there are unique designs that greatly improve equipment output and product quality.
1.Characteristics of extruder:The material of the screw barrel is 38CrMoALA nitrided treatment, which is wear-resistant and has a long service life; Gears and shafts made of high-strength alloy steel, carburized and ground treated; Using extra large thrust bearings for high torque output; Unique inlet design with perfect water cooling device; The screw cylinder with a grooved feeding bottom sleeve has enhanced feeding function, providing a guarantee for high-speed and high-yield extrusion. The design concept of low-temperature plasticization ensures the extrusion of high-quality products while achieving high-speed and high-yield extrusion;
Automatic PLC intelligent control can achieve linkage between main and auxiliary machines, with an easy to monitor human-machine interface for easy understanding of processing and machine status
