construction criterion

Positive effects on the economic efficiency of the MIM process:

• ideal shaping possibilities
• good mechanical properties
• low tolerance limits
• high surface quality

The MIM process is most economic where complex formed, small parts with high tolerance limits, good mechanical properties and high surfaces quality are required.

When, for example, precision casted parts which subsequently have to be machined, can be manufactured without machining, owing to the MIM process, a substantial economic advantage in favour of MIM can result.

In particular when the parts are extremely small (less than 20g) which makes machining difficult and therefore raising costs.

When the P/M process is out of question because of the complexity of that part or because of material properties, the MIM process offers an alternative.

When mechanical machining is limited by the material, the shaping possibilities of the MIM process are especially in the foreground.

MIM is a process which fundamentally opens new possibilities for the design engineer. It's very unique characteristics enable it to be applied where other processes reach their limits due to costs or quality reasons. Or where parts just cannot be manufactured by other process.
