The rubber extruder originated in the 18th century and is one of the types of plastic machinery. Based on the direction of the material flow of the die and the angle between the center line of the screw, the die of the extruder can be divided into a right-angle die and an oblique die. . The screw extruder uses the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix the material, relying on the die for molding. Single screw extruder, twin screw extruder, screwless extruder and multi-screw extruder are the basic classifications of plastic extruders.

Uses

Extrusion of profile:

Adjusting the speed of the extruder and changing the structure of the extruder screw can be more suitable for the production of various plastic profiles such as PVC and polyolefins.

Modified granulation:

It is more suitable for the blending, modification and reinforcement of various plastics.

Pipe extrusion:

It is more 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:

It is more suitable for the extrusion of PVC, PET, PS, PP, PC and other profiles and plates. Extrusion of various other plastics such as silk, rods, etc.
