The MIM process

The MIM process has become an important part of the metal manufacturing industries. The technology is derived from the injection molding of ceramic powder and metal.

The MIM process is capable of producing extremely complex parts in medium and large quantities, ensuring all the precision such parts require, at a low cost.

The fine powder used in MIM technology shows low surface roughness after sintering, ensuring a high-quality surface.

MIM DIFFERENTIALS

The MIM process

TOOLING

The development of the tooling is the first and main step of the MIM process. The quality of the tool is essential for the entire process.

We develop the tooling internally, guaranteeing the required quality with excellent cost-effectiveness.

METAL INJECTION MOLDING

In this step, fine metal powders are mixed with binders to facilitate the injection into the mold. The raw material is then injected into the mold cavity at a certain temperature and under high pressure.

The obtained parts are called green parts and are 20% to 25% larger than the final part, which allows for shrinkage during sintering.

BINDER EXTRACTION

After the molding process, the polymeric binders are extracted using a solvent. At the end of this step, the part is ready for sintering.

SINTERING

The part is sintered by the diffusion method that allows the metal particles to be densified. The pores are removed in this process, causing the part to shrink 75% to 80% of its molded size. The part reaches its final dimension and geometry after sintering.

There is no need for any secondary operations to improve dimensional tolerance and surface finish. If any component requires further processing, it is done in this step.

SECONDARY OPERATIONS

After sintering, several secondary operations can be performed to finalize parts, such as: milling, threading, turning, heat treatment, calibration, surface coating.
