Applications


Primarily serving as high-performance wear-resistant replacement parts for Twin Screw Extruders and Injection Molding Machines. Widely applied in high-intensity extrusion and plasticizing processes
 
1.Polymer Compounding and Modification: Essential for the extrusion, mixing, and pelletizing of high-performance engineering plastics, masterbatches, color concentrates, and heavily filled materials (e.g., glass fiber, carbon fiber), ensuring uniform dispersion and stable output.

2.Barrier and Separation: Utilizing the unique Barrier Grooves design, the screw allows for precise material flow separation and melt control, particularly for materials with dispersed particles, significantly boosting extrusion efficiency and final product quality

3.High-End Equipment Maintenance: Ideal for upgrading and replacing screw segments and barrel wear parts in major domestic and international extruder brands, including Coperion, Leistritz, Berstorff, JSW, and Maris, optimizing equipment lifespan and performance.
 
4.Processing of Thermoplastic/Thermoset Plastics, Rubber, and High-Precision Compounding in the food and pharmaceutical sectors.

 

Advantages


1.Extreme Hardness and Unmatched Wear Resistance
Precisely machined from integral Tungsten Carbide (WC) or Cemented Carbide, this component possesses hardness far exceeding traditional tool steel. It offers exceptional abrasion resistance and anti-scuffing properties when processing highly abrasive materials (e.g., mineral-filled or fiberglass-reinforced plastics).

2.Superior High-Temperature and Thermal Stability
Tungsten Carbide maintains its high strength and hardness even under the high temperatures generated during the plasticizing process. This effectively prevents softening or deformation under long-term, high-shear operation, guaranteeing consistent and stable extrusion.

3.Maximized Service Life & Reduced Operating Costs
The ultra-long service life translates directly into significant economic benefits. By extending the replacement cycle many times over compared to conventional screws, it dramatically minimizes production line downtime and maintenance costs, ensuring true cost-effectiveness.

4.Stable and Accurate Material Flow Control
The unique barrier flight design, combined with the material's resistance to deformation, ensures precise control over raw material flow. This is crucial for maintaining the batch-to-batch consistency and quality of the final product.
