About Us

Message from the Representative

This year marks the 45th anniversary of our founding. Our founder, Kazuo Hamada, was originally involved with press & mold dies at an electronic component manufacturer, and studied press & mold dies in the U.S., which was the leader in cutting edge technology at the time. After returning home, he made major contributions to the JIS standards for Japanese press & mold dies. This was based on the idea that “to produce high-precision press & mold dies, it is necessary to standardize the structures of them.” Since then, the press & mold dies, and production systems we have developed have been called the “world’s smallest” and the “world’s fastest,” and we have created advanced manufacturing that fits the times.

At present, the Japanese mold industry is buffeted by cost competition with companies in China, South Korea, and other emerging Asian countries, and is said to be losing its competitiveness. In contrast, we continue to pursue improving our own level of technology without falling down the path of making simple cost reductions, and are developing our own proprietary products. To do so, we need to have a certain business size. Taking on new things involves risks, and requires sufficient financial strength and production capacity to withstand them. We always make anticipatory investments and focus on our facilities and developing our human resources. Thanks to these initiatives, we receive orders from a broad range of countries worldwide.

By considering this period as the second stage of our founding and integrating mechanical and electric technologies for the press & mold dies, production, and equipment that we have cultivated so far, we will continue to take on challenges for creating new value.
