Profile

[Company strength]
Our company was founded in June 1965 in Fukuyama City, Hiroshima Prefecture. We are currently a general heat-treatment manufacturer with six factories in Hiroshima and Okayama Prefectures. We offer metal surface treatment ranging from materials to complete products by exploiting various kinds of techniques. These include annealing, normalizing, thermal refining, carburizing and quenching, vacuum hardening, high-frequency hardening, nitriding, and hard-shot peening. We have obtained many certificates for heat treatment from leading manufacturers of cars, construction machines, agricultural machines, heavy machines, and so on. We flexibly support a broad range of high-quality heat treatment needs for over 1,000 enterprise customers in and around the Seto Inland Sea region. We possess 13 devices for hard-shot peening treatment, which is our unique technology for improving the fatigue strength and pitching properties of gears and so on. We also feature specialized grinding processes for large parts (surface grinding, internal grinding, cylindrical grinding, honing).

[Representative's message]
Most of our current customers are based in the Chugoku and Shikoku regions, mainly including areas around the Seto Inland Sea. We hope we can make use of J-GoodTech to widely promote our techniques and quality beyond our current trading area to win new orders, despite logistics bottlenecks. We have been developing our technical capabilities for 50 years since our foundation. We aim to make use of these strengths to become a technical proposal enterprise capable of advising customers on optimal heat-treatment specifications from the design phase. This is how we will further contribute to regional industries. We also want to expand our current trading area in and around the Seto Inland Sea region to a nationwide scale by improving logistics.
