Corrosion Proof Screw Barrel for Extrusion of Reactive Polymers
Product Specifications
Screw Design
Double-screw
Twin Screw Type
Co-rotating Parallel Twin-screw
Product Description
This wear-resistant screw barrel for extrusion is specifically developed for abrasive plastic compounding tasks. By applying a nickel-based alloy cladding layer through laser technology, the inner surface achieves excellent durability against glass fiber, talc, or calcium carbonate-filled materials. Combined with high-precision CNC machining, it ensures long-term operation with minimal dimensional loss. Ideal for high-output twin screw extruders.
Advanced Building Block Design
The main screw and barrel of the split twin-screw extruder adopt an advanced "building block" design. The screw is composed of various screw blocks installed on the mandrel and barrel lining, forming a sleeve that can be adjusted according to different screw blocks. This design allows the screw component structure to be flexibly combined according to the process requirements of the material variety to achieve material transportation, refinement, shearing, and discharge.
This effectively solves the difficult-to-consider contradiction between the versatility and specificity of the screw, achieving the purpose of one machine with multiple uses.
Key Benefits
- Reduced maintenance costs: Worn components can be partially replaced, preventing the entire screw or barrel from being scrapped
- Material options: Available in Cr26, Nickel based alloy, or SAM26 materials
- High wear resistance: Specially designed for abrasive materials with glass fiber, talc, or calcium carbonate fillers
- Precision manufacturing: CNC machining ensures dimensional accuracy and long service life
