Corporate Information
Becoming a company that
develops powder metallurgy technology
to bring innovation to the industry
Although times have changed since the establishment of the company in 1944, Diamet has consistently valued the policy of meeting customer requests to the maximum extent with sintered products manufactured through the powder metallurgical method. Fortunately, we built a trusted relationship with global manufacturers in the automobile industry for many years.
However, without being arrogant about our history and past achievements, Diamet continues to accept the challenge of entering new fields.
This is because developing powder metallurgical technology with the strength of high quality realizing high precision and overwhelmingly high productivity has the potential of achieving a revolution in industries where sintered products are not yet in use.
Diamet will contribute to the field of electric vehicles (EV) increasing in the automotive market share each year, as well as to fields other than the automotive field, such as natural energy power generation.
Diamet is not afraid of changing to keep up with changing times and needs. The company will continue to create new value that makes the world more prosperous while listening to customer voices and using various talents of our employees in all departments.
