Metal Injection Molding (MIM)

MIM parts – Innovative and with highest precision

Metal powder injection molding offers a diverse selection of shaping options and is used wherever multi-layer component geometries are required. Moreover, a wide range of materials can be accessed.

Small to smallest precision parts with a high geometric complexity can be economically mass-produced with metal injection molding (MIM) due to the low error rate. The metal parts produced are characterized by high accuracy and an optimal surface quality. Therefore, MIM components do not require post-processing.

Materials that are particularly difficult to machine, such as titanium alloys or stainless steel, can be used productively with MIM, since there are no assembly and joining steps. Threads, bores, logos or other inscriptions can also be precisely worked into the component. However, since the metal powder injection molding is tool-bound, the tool costs must be amortized over the number of pieces.

As an experienced MIM manufacturer, we can ideally assist you in planning your MIM component.

Advantages of MIM

  • Great geometric design freedom
  • Production of complex parts
  • Internal & external threads can already be formed during casting
  • High dimensional accuracy
  • Unique level of detail
  • First-class surface quality
  • Good dimensional tolerances of +/- 0.5%
  • Better adhesion of anti-corrosion treatments
  • Relative density of 95-98%
  • Less complex processing
  • Low manufacturing costs
  • Economical even with medium quantities
