MIM Metal Injection Molding
(Metall injection molding)

With this technology, the advantages of plastic injection molding (geometric design freedom) are combined with the advantages that are known from powder metallurgy (processing of demanding, difficult or non-machinable, possibly also non-castable construction and functional materials).This makes it possible to mass-produce complex, ready-to-install molded parts made of metal with maximum reproducibility and a wide range of material properties.

Green part
Brown part
Sinter part
Injection-molded part with a binder content of approx. 10 percent by weight. By removing the first binder component, the so-called matrix,
the still unsintered, porous brown part.
Completely debindered and solidified by sintering component, which is dimensionally tightly tolerated and ready for installation.
- high density of 97%,
- homogeneous powder distribution,
- no alignment of the powder particles.
- Compliance with tight tolerances,
- Density of 97% of the theoretical density,
- round, separated, evenly distributed micropores,
- no crack formation due to micropores.
These properties lead to non-directional shrinkage and a high component density, which is a prerequisite for gas-tight sintered parts.
