Single screw extruder for plastic industry

Date:2022-3-20 Author:

Plastic single screw extruder for PE is used for plastic processing; The extruder machine is designed by one screw in the barrel. Our extruder machine has a competitive price with super quality.
It is generally used for processing both PVC,PE,PET,PP,ABS,PLA,PC and so on.Machine screw diameter ranges is from 25mm to 200mm.

Single screw extruder is consist of the famous brand and high-quality components such as screw and barrel, gearbox,Siemens/Schneider electric contactor,Japan RKC/Omron temperature controller, ABB inverter.
it can be used to making plastic pellets like PVC/PE/PP/ABS/PET an so on,and also used for produce PP/PE pipe, PVC hose,PP-R pipe,HDPE pipe and with downstream machines,such as die head, vacuum calibration tank, cooling tank, haul off machine,cutting machine, and stacking table,Printer and so on.

single screw extruder has the following applications:

Pipe extrusion: suitable for pp sheet extrusion-R pipe, PE gas pipe, PEX crosslinking pipe, aluminum-plastic composite pipe, ABS pipe, PVC pipe, HDPE silicon core pipe and various co-extrusion composite pipe.

Sheet and sheet extrusion: suitable for PVC, PET, PS, PP, PC and other profiles and sheet extrusion. Other kinds of plastic extrusion such as wire, rod, etc.

Extrusion of profiles: adjusting the speed of the extruder and changing the structure of the extrusion screw can be used to produce PVC, polyolefin and other plastic profiles. Modified granulation: suitable for mixing, modifying and reinforcing granulation of various plastics.
