Modular Design Nickel Alloy Twin Screw Barrel with Wear Resistance for High Torque Extruders
Our twin screw extruder barrels are specially designed for high torque co-rotating twin screw extruders used in engineering plastics, black masterbatch, biodegradable materials, PVC, WPC, and high-filled compounds.
During processing of glass fiber reinforced plastics, CaCO₃ filled compounds, black masterbatch, and mineral-filled materials, the barrel liner faces severe abrasive wear.
Our barrels use:
- HIP alloy liners
- Ni-based wear resistant alloys
- Bimetallic liner structures
- Vacuum heat treatment technology
This significantly improves barrel lifetime and reduces maintenance frequency.
Typical applications:
- PA6 / PA66 GF30-GF70
- Engineering plastics
- Black masterbatch
- Conductive compounds
- Magnetic plastic materials
- Filler masterbatch
For corrosive materials such as:
- Flame retardant compounds
- Fluoroplastics
- Biodegradable plastics
- Reactive extrusion materials
the barrel requires excellent anti-corrosion capability.
Our special alloy liner technology helps:
- Reduce corrosion damage
- Maintain stable screw clearance
- Improve process consistency
- Extend service life
