Detailed Technical Information
| Base Material | 1)38CrMoAlA(JIS SACM645) 2)Cr12MOV(JIS SKD-11) 5)9Cr18MoV |
| Bimetallic Alloy Materials | 1)Fe-based alloy 2)Ni-based alloy/Deloro alloy 4)NiCo-based alloy |
| Bimetallic Alloy level | Level A - containing Tungsten of 40% Level B - containing tungsten of 25% Level C - containing tungsten of 9.5% |
| Designing | Screw structure and compression ratio can be designed according to different products & different clamping force requirement. |
| Treatment Technology | 1)Longer time Gas Nitriding treatment 2)special anti-wear & abrasion alloy (bimetallic) 3)tungsten carbide 4)cobalt base alloy 5)stainless steel 6)Gh113 nickel based alloy Treatment Nitriding treatment(>100 Hours) Depth of Nitrided Layer: 0.5-0.8 mm Hardness of Nitrided Layer: >950Hv Hard Chrome Plating treatment: Thickness of Hard Chrome Plating Layer: 0.03-0.08mm Hardness of Hard Chrome Plating Layer: ≥950HV Nickel alloy plating.treatment: Bimetallic Barrel Centrifugal Casting (Inlay Alloy) Bimetallic Screw: Plasma Alloy Coating Spraying Depth of Bimetallic Layer: >2mm Hardness of Bimetallic Layer: HRC55°-65° |
| Material Application | 1)General Plastics 2)ABS,PA,PC,PE,PET,PP,PS,EVA,PU,PVC,U-PVC,etc 3)PA + GF(Glass Fiber) 4)Flame-resistant Reinforced Plastics 5)Modified Engineering Plastics 6)All kinds of Mixed Recycled Material(in Scrap or Granule),etc |
| Basic Infomation | Surface Roughness :Ra0.4um Linearity of the screw: ≤0.015mm Linear axis limit: ≤0.02mm Hardness after Hardening & Tempering: HB260-300 Fragility of Nitration:≤Two grade |
| General Terms | Means of transport: Ocean,Air,Express Production time: About 30 days after we receive the deposit and lead time will different according to the order quantity. |
| Warranty period | 1-2years(Depends on the plastic raw materials) Bimetallic: much longer lifetime. |
| Competitive Edge | 1.Long lifetime,low energy consumption. 2.Wonderful plasticizing 3. Top-quality bimetallic screw and barrel 4. High wear resistance, resistance to corrosion 5. Fast and On time delivery 6. Best customer after-sale service! |
