MIM technology concept MIM is a metal powder injection molding of the English phrases (Metal powder injection molding) referred to in the beginning of the principle of forming die, by injected metal powder so that it formed by a series of processing, have been shaping the piece, not only has a high degree of shape Similar, but with the original metal physics, chemistry and mechanical properties of this form of technology known as metal powder injection molding.MIM MIM process MIM applies to materials There are Fe alloys, Fe-Ni alloy, stainless steel, Kovar alloy, W alloys, titanium alloys. Stellite alloy, Si-Fe alloy, Hastelloy alloy, hard alloy materials, and so on. MIM process characteristics | MIM technical advantages MIM technology as a manufacturer of high-quality precision parts of the near-net shape technology, with conventional powder metallurgy, precision machining and casting methods unmatched advantages: Three-dimensional shape of the complexity of the plastic injection molding with a very High-precision (± 0.3% ~ ± 0.1%), the general need for follow-up processing High-precision±0.3%±0.1%,the general need for follow-up processing Relatively high density (≥ 95%) Relatively high density (≥ 95%) Good surface finish, 32 ms or better Product strength, hardness, elongation, and other mechanical properties, wear resistance, fatigue resistance, uniform organizations Alloy with a wide choice of available technology to other manufacturers could not produce a special performance parts Good mechanical properties, and the forging of a very similar materials With a high degree of automation, simple process, the quality of stable and continuous high-volume production Very cost competitive advantage, usually to save more than 20%, and shorter delivery times MIM precision casting and forming the ability to compare Characteristics | Casting | MIM | Most small hole diameter | 2mm | 0.4mm | 2mm diameter of the largest blind hole depth | 2mm | 20mm | Minimum wall thickness | 2mm | <1mm | Heavy wall thickness | Unlimited | 10mm | 4mmdiameter tolerance | ±0.2mm | ±0.06mm | Surface roughness (Ra) | 0.005mm | 0.001mm |
