What is MIM?
Metal powder injection moulding (MIM) is a manufacturing method for metal products by injection moulding material called feedstock, which is a mixture of metal powder and a binder made of resin, wax, etc., into a mould and sintering them.

What is μ-MIM®?
μ-MIM® is a technology that realises ultra-precise MIM components. It is a technology that includes not only miniaturization of the product size but also its accuracy and quality assurance.
μ-MIM® meets the following demands.
- ▪ Mass production of components and materials that are difficult to machine
- ▪ Integration of small components that are difficult to assemble
- ▪ Mass production of components with size and tolerance requirements that are difficult by conventional MIM production
- ▪ Add value to components by integrating functions
In conventional MIM, most of the parts have a size of several millimetres to several centimetres and must satisfy the dimensional tolerance of
about 5-10% of its size.
The product size is smaller, the required tolerance is also smaller thus the difficulties of manufacturing is increased.
μ‐MIM® realises mass production in that area
