company

Based on the high-precision/strength hot forging technologies we have developed through manufacturing golf club heads, we provide integrated services covering everything from forged part development to mold fabrication and manufacturing for a wide range of industries, including two-wheeled vehicle and automobile parts such as engine gears and transmission gears, and agricultural machinery parts.

Utilizing “Metal Sleeve,” our independently developed 10-µm ultra-thin seamless metal pipe, our products deliver great strength not only in OA device parts and electrical devices, but also in fields requiring high precision and high strength, such as automobile parts, aircraft parts, medical device parts, motors, batteries, and electronic parts.

As a manufacturer specializing in forged golf club heads since 1968, we have been operating an OEM business and selling products under the EPON GOLF brand. We provide integrated services covering everything from development and mold fabrication to manufacturing, and have won high acclaim from well-known brands inside and outside Japan, boasting an 80% share of the domestic brand forged iron club head market (according to internal research).

We manufacture medical devices (implants) such as artificial joints and bone-junction plates, utilizing our precision forging technology and processing technology for medical alloys (titanium alloys, cobalt-chromium alloys, and high-nitrogen stainless steel). We can flexibly handle everything from small-batch high-mix production to mass production. We obtained ISO 13485 certification in 2011 (obtained by Medical Devices Department).

We have obtained AS9100 certification, an international quality management standard for the aerospace industry (obtained by Aerospace Business Office). We manufacture aircraft engine parts by utilizing the advanced technical skills and quality control systems we have developed through manufacturing medical device parts. We are also involved in developing forging technologies to help increase precision and strength, and to reduce costs.
