Conical Twin Screw Application
1)PVC pipe extrusion line;
2)PVC sheet extrusion line;
3)PVC profile extrusion line
4)WPC extrusion line;
5)PVC granulation/recycling line;
6)PVC foaming board production line;
The material can be new or recycle, the material can compound calcium power 5%-300%.


  • Bimetallic Treatment of Screw
The bimetallic screw for extruder twin screw is a kind of screw spray welding a 2~3mm-thick alloy coat on the screw flight of output area for the screw . The Bimetallic treatment has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided screw.


PTA Machine
The bimetallic treatment of our screw by the PTA machine. It is a advance equipment which has not been broadly used in bimetallic treatment. Compare to the manual process the advantage is better temperature stability, dense structure and uniform thickness and not liable to crack.


Customized Design
We can design the screw construction for you according to your finished products. Our factory have more than 15 years experience in producing screw barrel.


Bimetallic Treatment of Barrel Type A
SKD11/SKD61 whole length bimetallic sleeve/pipe insert into the barrel by jack The thickness of the bimetallic sleeve 8~10mm, which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided barrel. Bimetal has more obvious advantages when processing high calcium carbonate powder PVC mixture to enhance the abrasion life.


Bimetallic Treatment of Barrel Type B
Another bimetallic barrel is machining the grooves at output section of the barrel then spraying the alloy powder on the groove. The length is about 400-500mm.
