There is a place for each of the traditional metal-forming processes: each has its own strong suits as well as its limitations. But wherever a component fabrication choice exists between MIM(Metal Injection Molding) and one or more of the other processes, it pays to see how they stack up in a head-to-head comparison.
The following table shows how the four major processes fare in some of the more important parameters to consider.
MIM vs. Conventional PM
- MIM can produce geometries that eliminate secondary operations
- MIM offers superior density, corrosion performance, strength, ductility
- MIM can combine two or more PM components into one, reducing part count
- MIM parts offer superior magnetic performance
MIM vs. Machining
MIM vs. Investment Casting
- MIM can produce thinner wall sections, sharper cutting points
- MIM produces better surface finish
- MIM is better for small-diameter blind and through holes
- MIM greatly reduces requirements for finish machining
- MIM produces high volumes of small components at a lower cost, faster lead times
