Metal Injection Moulding (MIM) - Powder Injection Moulding

MIM = Metal Injection Moulding
Serial production of high strength precision components by injection moulding of metal powder offers possibilities and advantages which cannot be achieved with alternative manufacturing processes such as hot pressing, precision casting and machining except maybe with con-siderable efforts.

MIM = Fabrication in Just Four Steps
Metal powder of a defined composition is mixed with a thermoplastic binder and granulated to form a feedstock. Similar to plastics, this feedstock is injected into a mould. The binder is then removed from the green part and the powder-metal skeleton is sintered to a dense component at temperatures between 1200°C and 1400°C. The sinte-red part can generally be used directly. Alternatively, all conventional post treatments can be applied to the material in question. The shrinkage occurring during sintering is allowed for in the design of the mould as an oversizing factor.

MIM = Max. No. of Parts / Min. Postprocessing
The MIM process is especially suitable for components with complex geometries in large quantities since the process can be fully auto-mated. Precision casting is also suitable for complex geometries, but results in higher tolerances. Due to the high manual effort required, it makes more sense economically for smaller production quantities. Other powder metallurgical production processes such as uniaxial pressing are also appropriate for large production quantities but only less complex geometries can be achieved by these processes.

About us

Company portrait

The MIM expert group is a technical working group of the German powder metallurgy committee, supported by the Fachverband Pulvermetallurgie, the Verein deutscher Ingenieure (VDI), the Deutsche Gesellschaft für Materialkunde (DGM), the Deutsche keramische Gesellschaft (DKG) and the Verein deutscher Eisenhüttenleute (VdEH).

The MIM expert group consists of industrial companies and research institutes. MIM parts producers co-operate closely with powder and feedstock suppliers, as well as with injection moulding machine or furnace distributors and research facilities. At the moment, more than 35 members are organised in the MIM expert group. Meetings are scheduled twice a year.

The work of the MIM expert group focuses entirely on Metal Injection Moulding. The injection
moulding of hard metals or ceramics are excluded.

The main objectives of the MIM expert group are:

      ■  The dissemination of MIM (MIM Technology Marketing)
      ■  The advancement of MIM (MIM development)
      ■  The coordination of interest with international associations,
      ■  e.g. Euro-MIM, MIMA, JPMA (Networking)
