Characteristics:
JJM series parallel twin screw barrel is suitable for extrusion of PVC powder. Equipping with different molds and auxiliary machines can produce all kinds of PVC plastic pipe, profiles, plates, sheets, rods, and granulation. Screw uses oil cooling system, while barrel using a special air cooling system. According to different requirements of customers, equipped are most reasonable screws to achieve optimal plasticizing and material quality.
 
Screw is made by high precision dedicated CNC screw milling machine, to ensure the performance of high extruding consistency. We introduce the most advanced variable pitch and screw design technology, so that the material in the screw shear and compress softer, which is closer to actual needs.

 

Parallel twin screw extruder is characterized with low shear force, especially for high-speed extrusion, and large diameter pipe extrusion.

We can do any kind of screw barrel for extruder molding machine, injection molding machine and blow molding machine, and all Screw barrel attachments etc.
