Pipe extrusion: suitable for PP-R pipe, PE gas pipe, PEX cross-linked pipe, aluminum-plastic composite pipe, ABS pipe, PVC pipe, HDPE silicon core pipe and various co-extruded composite pipes.
Extrusion of sheet and sheet: suitable for extrusion of profiles and sheets of PVC, PET, PS, PP, PC, etc. Extrusion of other various plastics such as silk, rods, and the like.
Extrusion of profiles: Adjusting the extruder speed and changing the structure of the extrusion screw can be applied to the production of various plastic profiles such as PVC and polyolefin. Modified granulation: suitable for blending, modifying and reinforcing granulation of various plastics.
Advantages and disadvantages
Advantages: The single-screw extruder is simple in design and inexpensive, so it is widely used.
Disadvantages:
(1) The material conveying of the single-screw extruder is mainly based on friction, which limits the feeding performance. It is difficult to add powder, paste, glass fiber and inorganic filler.
(2) When the head pressure is high, the countercurrent is increased to lower the productivity.
(3) The material of the single-screw exhaust extruder has a small surface renewal effect in the exhaust zone, and thus the exhaust effect is poor.
(4) Single-screw extruders are not suitable for certain processes, such as polymer coloring, processing of thermosetting powders, and the like.
