SJ Single Screw Extruder/PP PE Extruding Machine

As a common extruder equipment, 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 by one-third of each.

The high-efficiency 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, high shear and low melting temperature Ensure high-performance low-temperature low-pressure metering extrusion of materials. Design concept and characteristics: high-speed, high-yield extrusion based on high flatness.

Function：

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

Profile extrusion: adjusting the speed of the extruder and changing the structure of the extruder screw can be used to produce various plastic profiles such as PVC and polyolefins. Modified granulation: It is suitable for blending, modifying and enhancing granulation of various plastics.
