Matched precisely to your working conditions and application requirements
| Material Type | Treatment Process | Surface Hardness | Applicable Working Conditions | Service Life |
|---|---|---|---|---|
| Nitrided Steel (38CrMoAlA) | Gas Nitriding | HV 900-1100 | Ordinary unfilled and non-corrosive materials (PE, PP, PS) | 1-2 years |
| Bimetallic Screw | PTA Surfacing / HVOF Tungsten Carbide | HRC 60-65 | Glass fiber reinforced and mineral filled engineering plastics | 3-5 years |
| Bimetallic Barrel | Centrifugal Casting of High Chromium Alloy | HRC 58-62 | Highly filled and highly abrasive materials | 3-5 years |
| Stainless Steel (316L) | Integral Quenching + Electropolishing | Approx. HRC 55 | Food and pharmaceutical grade products, weakly corrosive materials | 2-3 years |
| Hastelloy C276 | Integral Machining | HRC 40-45 | Highly corrosive materials (fluoroplastics, chlorine-containing plastics) | 3-4 years |
| Fully Hardened Powder Alloy | Integral Sintering | Above HRC 65 | High temperature, high abrasion, high corrosion (PEEK, LCP) | 5-8 years |
Critical Notes:
• For materials containing over 30% glass fiber, bimetallic screws and barrels are mandatory.
• For rigid PVC processing, corrosion-resistant materials or chrome-plated surfaces are required.
