Screw barrel structure design increase production for injection extrusion plastic machine
Screw Types and characteristics
Gradual screw features: long compression section, accounting for 50% of the total length of the screw, energy conversion eased during plasticization, mostly used in PVC and other plastics with poor thermal stability.
Characteristic of catastrophic screw: Compression section is short, accounting for about 5%~15% of the total length of screw, energy conversion is more intense when plasticizing, and it is mostly used in crystalline plastics such as polyolefin and PA.
Universal screw features: versatile screw with strong adaptability, can adapt to the processing of a variety of plastics.
