Advanced barrier design generates pressure that forces air bubbles back to the feed side, preventing intrusion in melted resin. Particularly effective with bubble-generating resins including PS, PA, PET, and EVOH.
- PP, PE, PVC materials
- WPC (Wood Plastic Composite)
- Sheet, pipe, profile, and foam board production
- Granular twin screw extruders
Our bimetallic extruder twin screws feature a 2-3mm thick alloy coating on the screw flight of the output area. This treatment provides exceptional corrosion resistance, abrasion resistance, and high-temperature performance. The bimetallic construction significantly extends service life compared to standard nitrided screws.
