Research & Development

Since its establishment, YUKEN has been committed to its focus on research and development in the field of surface treatment.

As an innovation-oriented corporation, Yuken’s core management policy is the creation of highly innovative products. Strong product development is the reason why YUKEN is recognized as the leading company in the surface treatment market, and we continue to develop surface treatment products.

YUKEN industry, the core of the YUKEN Group, has the Technology Center (right building in photo) as the group’s center for all research and development. The Technology Center is a well-equipped facility conducting a range of work from fundamental research to applied technology research related to surface treatments.

These technologies are constantly being reviewed to align with the company's marketing policies in its commitment to provide top-tier customer services. YUKEN has gained recognition from business partners in major Japanese automotive and electronics OEMs.
