Stamping/Fine Punching/Screw Processing: Similar to plastic injection moulds, complex three-dimensional geometry can not be generated by stamping, fine blanking or screw processing, while metal injection moulding will be easier.
Traditional powder metallurgy powder with small size (usually less than 25 micron) can be used in MIM, which is better than traditional powder metallurgy powder. Small scale results in relatively high free surface area, which makes MIM sintered through composition to near density. In addition, MIM processes allow for more complex designs.
NC machining and EDM: The use of metal injection moulds for multi-cavity moulds can improve production efficiency and reduce the cost of components.But through NC or EDM, which is difficult to match.
Die-casting: MIM can handle superalloys more than cast superalloys, because MIM alloys are never melted - polymer binders make powders shape at temperatures similar to plastic injection moulding. This also results in a long tool life and a cavity life of more than 250,000 rods without rework.
Investment casting: MIM is better than casting in filling, thin section, surface finish and accurate details. MIM is more competitive than investment casting.
