Metal injection molding components

Metal injection molding offers a manufacturing capability for producing complex shapes in large quantities. The process utilizes fine metal powders (typically less than 20 micrometers) which are custom formulated with a binder (various thermoplastics, waxes, and other materials) into a feedstock which is granulated and then fed into multiple cavities of a conventional injection molding machine. After the “green” component is removed, most of the binder is extracted by thermal or solvent processing and the rest is removed as the component is sintered (solid-state diffused) in a controlled atmosphere furnace. The MIM process is very similar to plastic injection molding and high-pressure die casting, and it can produce much the same shapes and configuration features. However, it is limited to relatively small, highly complex parts that otherwise would require extensive finish machining or assembly operations if made by any other metal forming process.CategoryMaterialLow Alloy SteelFe-2Ni, Fe-2Ni-0.5C, Fe-2Ni-0.5C-HT, Fe-8Ni, SAE 4650Stainless Steel316L, 430L, 440C, 440C-HT, 17-4PH, 17-4PH -HT, HK 30, SUS 420J2, SUS 310Hard AlloyWC-Co(6%)Low Expansion AlloyKovar, InvarTool SteelM2,42CrMo4Heavy Alloy90Fe-Ni, 92W-Fe-Ni, 95W-Fe-Ni FieldsPartsAutomobile IndustryTurbo, brake component, ignition control lock part, engine part, sensor part…Medical ApparatusOrthodontics brackets, implanted device…ElectronicPrinting head, cable connector, laptop hinge, mobile phone crust, hard disc drive parts…Consumer ProductsWatch case, watch chain, golf head, lock part, gear parts...Mechanical IndustryCutting tool, micro gear wheel…ToolsBlade clamp, drillstock…
