As a member of the Daido Steel Group,
we have strengths in processing special steel and are confident in our ability to make proposals.

DPI is a group company of Daido Steel, and its main business is metal processing. Our group companies are working together to meet the needs of the world and respond to changing needs.

The Daido Steel Group works together to supply materials and material process services to meet customer requests.

The Daido Steel Group's strength lies in its wealth of know-how in the development, procurement, and processing of special steel. Daido Steel sometimes develops non-standard materials to meet various needs. Therefore, we have the advantage of being able to utilize this information to examine the characteristics of special materials and appropriate processing methods. We can also suggest the best materials for your products and applications.
In addition to proposing Daido Steel's original materials, our group companies can also work together to develop materials that meet the performance, cost, and quantity requirements of our customers. Therefore, we are also relied upon as a source for materials consultation.

We can manufacture parts in line with changes in the automotive industry.

Another characteristic of the Daido Steel Group is that it does a lot of business with automobile-related companies. The automobile industry is entering a period of major change, including electrification. Therefore, there is a growing need to manufacture parts using new materials such as magnets. In order to quickly respond to the latest customer needs, our group companies are working together to create a system that allows us to grasp and share the trends of the new era.
In the future, we would like to leverage our technology and know-how cultivated in the automobile industry to continue technological innovation, so that we can contribute to fields where the need for special steel is increasing, such as aerospace and ships.
