- Centrifugal casting or hardfacing for bimetallic liner
- Precision grinding and polishing of screw surface
6. Testing & quality:
- Dimensional inspection (CMM)
- Hardness testing of coating
- Performance trials in extrusion/injection setup
1. Dimensions:
- Barrel diameter (outer): 80 mm to 250 mm (customizable)
