MIM technological characteristics
MIM technology as a kind of manufacturing high quality precision parts near net forming technology, with a conventional powder metallurgy、machining and precision casting method incomparable advantage;
1) Structure is unlimited: To product the complex metal parts as plastic molding, formed directly, structure is not restricted;
The item molding shape by plastic can be achieved by MIM can be art.
We can design poriferous、concave and subsidence, and design screw thread、knurl、lettering、engraved brand, etc；
2) Easy to mass production：It is suitable for continuous production, large quantities of bulk demands larger product highlights technology advantage
3) Physical performance are reliable: products have a good organization uniform and density, density can be up to 95%– 99% of theoretical density;；
Products are of good surface finish，the process directly to Ra1.6, also can make ordinary polishing、mirror polishing；
According to the need for carburizing、quenching and tempering heat treatment, etc
Surface is also needed for electrophoresis、plating (nickel plating、hard chromium、gold、silver etc.)、vacuum coating and other surface treatment；
4) Product is high quality precision: One molding product size precision can be up to + / - 0.1 ~ 0.5%, and general precision requirements of the product can be directly production guarantee, part of the position with high dimensional accuracy requirements can also be through additional machining further ascension;
5) Vary material available: special purpose alloy are apply to the MIM process ,like stainless steel、soft magnetic alloy、iron nickel alloy material、tungsten alloy、tool steel, etc.
6) Apparently low costs: complicated structure parts under the condition of large quantities and mass production, the cost can be greatly reduced.
