Pelletizing Vented Single Screw Extruder Plastic Filament Extruder Custom

Single Screw Extruder 

A single screw extruder is one of the most widely used machines in the plastics processing industry. Designed for stable melting, plasticizing, conveying, and shaping, the single screw extruder offers excellent performance in pipe extrusion, sheet extrusion, profile production, wire coating, and plastic pelletizing. With a simple structure, easy operation, and high efficiency, it is ideal for both production lines and recycling applications.

The extruder features a high-torque motor, optimized screw design, advanced temperature control, and stable pressure output, ensuring consistent material quality. It is suitable for processing a wide variety of thermoplastics, including PE, PP, PVC, HDPE, LDPE, ABS, PS, and biodegradable materials. Thanks to its durability and versatility, the single screw extruder is widely adopted in plastic product manufacturing, polymer modification, and recycling plants.

Applications of the Single Screw Extruder

Pipe & Tube Extrusion: PE, PP, PVC, and PPR pipes.

Sheet & Film Extrusion: PET, PP, PS sheets and films.

Profile Extrusion: window profiles, cable channels, construction trims.

Granulation & Pelletizing: PE/PP pellets, recycled plastic granules.

Wire & Cable Coating: insulation and sheathing extrusion.

Plastic Recycling: melting and reprocessing post-consumer or industrial waste.
