What are the design concepts and characteristics of a single screw extruder

As a common extruder equipment, the single screw extruder is used in the plastic processing industry. What is the principle and structure? The following is an analysis of the principle of the single-screw extruder from the conveying section, compression section, and metering section of the extruder.

The single-screw extruder is generally divided into three sections in terms of effective length. The effective length of the three sections is determined according to the size of the screw diameter, the pitch and the depth of the screw, which are generally divided into one third of each.

The single-screw extruder adopts a two-stage overall design to strengthen the plasticization function to ensure high-speed, high-performance and stable extrusion. The special barrier comprehensive mixing design ensures the mixing effect of the material, and the high shear and low melting temperature are guaranteed. High-performance low-temperature low-pressure metering extrusion of materials. Design concept and characteristics: high-speed and high-yield extrusion based on high flatness and straightness.

Pipe extrusion: suitable for PP-R pipes, PE gas pipes, PEX cross-linked pipes, aluminum-plastic composite pipes, ABS pipes, PVC pipes, HDPE silicon core pipes and various co-extruded composite pipes.

Sheet and sheet extrusion: suitable for the extrusion of PVC, PET, PS, PP, PC and other profiles and sheets. Extrusion of various other plastics such as silk, rods, etc.

Extrusion of profiles: Adjusting the speed of the extruder and changing the structure of the extruder screw can be suitable for the production of various plastic profiles such as PVC and polyolefins. Modified granulation: It is suitable for blending, modifying and enhancing granulation of various plastics.
