Possible to create 3D complex shapes
on the order of millimeters
We are confident about micro-molding skills and create a future with micro parts
MIM (Metal Injection Molding) is a metalworking process in which finely powdered metal is mixed with binder material to create a "feedstock" that is then shaped and solidified using injection molding.
From very early on, we focused on Metal Injection Molding and conducted research and development without relying on technology imports from the U.S. In 1991, we acquired a patent in the U.S. and accomplished a base of Metal Injection Molding.
At each base factory, we handle thin-wall and complex shape products through an integrated system from mold manufacturing to raw material production.


More than 90 % of the productions have been operated overseas factories.
It is possible to suggest a reduction of initial tooling cost because the molds are manufactured in-house. Mold productions have various patterns according to the production lot and shapes.
Both domestic and overseas factories have operated quality control under the steady management system that acquired ISO9001.
We have many years of experience in factory management, including employee training by Japanese personnel in overseas factories.
We have multiple base factories in Japan, Thailand, the Philippines, and Colombia.
Since they do not depend on one factory, it is possible to realize a steady supply even in an emergency.
It is good at forming fine 3D complex shapes and has excellent mechanical strength compared to conventional sintering.
It is possible to produce fine parts with high dimensional accuracy and excellent surface.

Manufacturing Process

01. Feedstock Preparation
02. Mixing
Combine metal powders with binders
03. Injection Molding
Create molded body by injecting heated compounds into the inside of molds
04. Thermal debinding
Remove organic binder from the molded body
05. Sintering
Create high-density sintered body at a high temperature
06. Inspection
Inspect the quality according to various quality standards
Injection Molded Body and MIM Sintered Body
The one on the left is the molded body, and the one on the right is sintered body. It is possible to produce highly precise products because the shrinkage is approximately equal.
The body made by MIM has excellent mechanical strength properties because its density reaches over 95% and its vacancies are spherical and independent.
Conventional Sintering
Conventional Sintering
The body made by standard sintering has poor mechanical strength properties because its density reaches only 88% and its vacancies exist along the grain boundary irregularly.
It indicates properties similar to that of molten material such as torsion and spring. (The products in the photo are made of SUS304)
