Metal injection molding (MIM) materials

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.

Background of metal injection molding

How does the production of MIM components work? What is the background of the MIM process? We would be happy to give you a comprehensive overview.

More about the mim process

In the process of metal powder injection molding, injection molding and sintering are used in combination. Fine metal powder is mixed with an organic binder and pressed into the desired shape during powder injection molding. The binder is then removed, and the molded part is sintered in the oven at high temperatures. The purely metallic end product receives the mechanical advantages of sintered components with the greatest freedom of design thanks to injection molding.
