MIM is quite often confused with sintering in which rather flat and less complex geometries are pressed and then sintered. Compared to machining or sintering of simple and rotationally symmetrical components MIM is usually at a disadvantage in terms of costs. However, MIM technology has always an advantage where complex geometry, special material requirements and low error quote are required or expensive rework should be avoided. MIM allows undercuts, drilling, thread, Logos and marks to be integrated directly into the component or even entire assemblies can be manufactured in one piece. In addition, the density of MIM parts is evenly distributed and densities of 96% to 100% can be achieved.
Advantages of MIM in short:
- Manufacturing of complex geometries without rework (saving of expensive process steps)
- Economic manufacturing process for small or medium-sized components
- Excellent surface quality
- High density
- Large choice of materials: e.g. stainless steel, iron-nickel alloy, soft magnetic alloy, special alloys (special customer requirements)
