What Are The Main Uses Of PE Single Screw Extruder?

Pulished on May. 20, 2019

As a common extruder equipment, the PE Single Screw Extruder is used in the plastics processing industry. It is mainly used to extrude thermoplastics such as soft and hard polyvinyl chloride and polyethylene. It can process a variety of plastic products, such as blown film. Squeeze, press plate, pull ribbon, etc., can also be used for melt granulation. The plastic extruder has advanced design, high quality, good plasticization and low energy consumption. It adopts involute gear transmission, featuring low noise, stable operation, large bearing capacity and long service life.

Let me give you a brief introduction about the main uses of single-screw extruders.

The PVC Single Screw Extruder generally determines the three effective lengths according to the screw diameter, pitch and screw depth, and each of them is divided into one-third divided into a conveying section, a compression section and a measuring section. The conveying section starts from the last thread of the material port, mainly preheating, compacting and completing the conveying task. The second section is the compression section. The temperature is to reach the degree of plasticization of the material, mainly by compressing the plasticized material to the third section. The third section is the metering section. The material maintains the plasticizing temperature and accurately and quantitatively transports the melt material for feeding to the machine head.

The main use of single-screw extruders is pipe extrusion, such as PP-R pipe, PE gas pipe, PEX cross-linked pipe, aluminum-plastic composite pipe and co-extruded composite pipe; sheet and sheet extrusion, such as PVC, PET, Extrusion of profiles and plates of PS, PP, PC, etc.; extrusion of profiles, suitable for the production of various plastic profiles such as PVC and polyolefin; modified granulation, suitable for blending and modification of various plastics, Enhanced granulation. In addition, the single-screw extruder can be applied to all thermoplastic extrusion and extrusion granulation.

The design concept of single-screw extruder mainly includes high-speed and high-yield extrusion on the basis of high quality; low-temperature plasticization to ensure the extrusion of high-quality products; strengthening plasticization function, comprehensive mixing design to ensure the mixing effect of materials Unique inlet design with perfect water cooling device; enhanced feeding function.
