The soft plasticizing designing ensures the quality of materials.
Effective designing theory guarantees the reliable running for extrusion. The high torsion moment adopts special driving force with gear or shaft of high intensity alloy steel, which was processed by penetrating carbon and gear grinding.
The newly developed screw can be fit for method of high feeding, ensuring the good fullness and the best feeding distribution for screw
The core temperature adjusting device and good feedstuff cylinder cooling in the screw ensures the exact control on the temperature of materials.
It along with various die heads , and auxiliary machines is to be used to extrude all kinds of piping, sheets, and strangely-shaped materials and soft and hard PVC granules.
