Metal Injection Molding(MIM) Compare to other processes

Stamping/ Fine Blanking/ Screw Machining: Similar to plastic injection molding tooling , complex 3-dimensional geometries impossible to produce
by stamping, fine blanking or screw machining but easily produced in metal injection molding.

Traditional Powder Metallurgy: Small powder sizes (typically < 25 um) can be used in MIM, smaller than the powder used in traditional powder metallurgy. The small size leads to a relatively high amount of free surface area, which during sintering allows MIM
components to sinter to near full density. Also, the MIM molding process allows for
more complex designs.

CNC Machining/EDM: The MIM mould use of multi-cavity tooling can provide high production rates and lowers component costs in MIM that are difficult to match
by CNC machining or EDM.

Die Casting: MIM can handle higher-temperature alloys than die casting, since the
MIM alloys are never melted – the polymer binder allows the powder to make the
desired shape in a die at temperatures similar to plastic injection molding. This also
results in very long tool life, with cavity lifetimes of over 250,000 shots without
needing substantial rework.
Investment Casting: MIM does better than investment casting in filling out thinner
sections, surface finish, and providing accurate details. The smaller the piece is, the
more competitive MIM than investment casting.
