Corporate philosophy

As a manufacturing group and technology group that always supports the times, Sanyu Giken strives to perform work of which we can be proud. In our mold making for various industries, including the automotive industry, we continue to advance to achieve the best with the concept of three keywords.

1. Mission
We value trust and manufacture quality molds with proven technology.
Taking swift actions to immediately answer our customers' needs.
Responsibly keeping a good conscious as we steadily enrich our employees' lives and contribute to society.

Sanyu Giken is a Japanese manufacturing company specializing in mold making and metal machining.

As a designer and manufacturer of molds, we offer aluminum die cast molds mainly for manufacturing automobile power trains and steering. We manufacture a wide range of mold sizes from 125t to 3,000t, which are delivered to countries around the world, including Japan, Europe, Asia, North America, and South America.
Globalization is also advancing in our industry, yet Sanyu Giken continues to manufacture our products in Japan because Japanese advanced technology is required to manufacture complex products that require high quality. For more than half a century, our group of advanced engineers has been committed to making "only one" products in the world and supporting the needs of our customers both in Japan and overseas.
