Pressure is generated when 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. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.

The bimetallic screw for extruder twin screw features a 2-3mm thick alloy coat spray-welded on the screw flight of the output area. This treatment provides excellent corrosion resistance, abrasion resistance, and high working temperature capability. The useful service life is significantly improved compared to common nitrided screws.
We can supply specialized screw configurations for various applications including:
- PVC/PE Film Blowing Screw
- Blow Molding Screw
- PS/PE/PP/ABS Sheet Extrusion Screw
- PE Aluminum Plate
- PPR Pipe Screw
- EVA Extrusion Screw
- HDPE High Efficiency Screw
- PET Straps Screw
- XPS/EPE Foamed Screw
- Granulation Screw, Vented single screw, and more
