1.Low price: single-screw extruders are compact and inexpensive. Twin-screw extruders are more than twice as expensive as single-screw extruders.
2. Simple recipe: single-screw extruders have a relatively simple process and recipe
3. wide range of applications: single screw is suitable for melt extrusion of polymers,
for extrusion processing of pellet feed, such as forming, film blowing machines,
injection processing, etc., and for a wide range of applications of raw materials.
4. Easy maintenance: In terms of maintenance, the single screw is simpler than the
twin screw because the structure of the single screw is very simple and facilitates maintenance.
5. Basic principle of conveying: The conveying of single-screw extruders depends
on the sliding friction formed between the raw material and the barrel.

Single Screw Extruder
The single-screw extruder is equipped with a smooth or slotted feed barrel and has length-to-diameter ratios from 8 to 32.
It is mainly used to process melts with venting or vacuum for recycling or product extrusion, which typically includes polyolefin and engineering recycling, melt blow moulding of fabrics, direct extrusion of engineering plastics into films, sheets, plates, pipes and profiles such as PET, PA, PBT, ABS PC.
Our newly designed GS series high-efficiency single-screw extruders have innovative features focused on energy savings, more precise process control and higher output.
We can guarantee you quality service and products with our experience and expertise, depending on your requirements for single screw extruders. Our experts will be happy to give you the expert advice you've been given, so talk to us today to find out more.
