4 . Comparsion of the output (LDPE)

Pressure is generated if resin passes over the barrier, forcing any air in the melted resin back to the feed side and effectively preventing the intrusion of air bubbles on the sub flight side. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.

5 . Parallel twin screw and barrel application
1)PP
2)PE
3)PVC
4)WPC
5)SHEET/PIPE/PROFILE/ FOAM BOARD
6)CRANULAR TWIN SCREWS EXTRUDERS

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.

6 . As per customer's demand,we can also supply below:
PVC/PE Film Blowing Screw;

Blow Molding Screw;
