History

Our company was established in 1951 as a trading company handling non-ferrous metal materials and has enhanced our function as a manufacturer. We have kept on challenging new fields looking ahead into the needs of the times based on the mobility of our function as a trading company and the technical capabilities of our function as a manufacturing company as two wheels.

  • Started production of HDD parts

Commentary

We manufactured and sold steel belts as mechanism components that drive the magnetic heads of hard disk drives (HDDs) at high speed. Since there were countless microscopic cracks on the end face of a steel belt, we performed the PSP process, which was a polishing technology we developed in order to eliminate the cracks. This enabled the extension of the service life, which was highly evaluated as an industry standard.
