Manufacturing Consideration

In MIM tooling Mold (Core, Cavity) use for manufacturing the parts as per customer requirements. MIM tooling looks like plastic injection molding Mold.

Tools in MIM are made by considering the high temperature and pressure, which is required to inject of the metal feedstock into cavity. The quality of the tooling directly impacts the final product’s accuracy, surface finish, and overall performance.

The success of MIM largely depends on the quality and design of the tooling used in the process. 

Considerations When Designing a Tool :

Material Selection

Material Selection

The selection of the right material for tool manufacturing is an important factor in the MIM process. tool material must be able to withstand high pressures, high temperatures, and tool material should have good wear resistance. In MIM tooling use tool steel such as A2, D2, H13, and hardened stainless-steel alloys.


Part Geometry

The tooling design will be significantly affected by the part design's complexity. We Consider some factor for tool design such as wall thickness, undercuts, draft angles. Proper consideration of part geometry will result in a more efficient production process and higher-quality parts.



Shrinkage is the contraction of a metal and binder component as it after the sintering process. The Mold cavity is sized approximately 15% to 20% oversize to compensate for shrinkage that takes place during sintering.

Surface Finish

Surface Finish

The surface finish of the MIM tool plays a critical role in determining the quality of the final product. A well-polished tool surface will yield a better surface finish in the molded part, reducing the need for post-processing steps like polishing or grinding.

Draft angle

Draft or Draft angle

Draft creates a taper on the faces of the part, which prevents them from being parallel to the Mold opening's movement. The part's ejection from the mold prevents scraping from causing damage.
Typically, draft angles range from 0.25 to 0.50° and walls should be a uniform thickness.
