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.
