What KUNO Kinzoku does

KUNO Kinzoku Industry Co., Ltd. is a privately held Japanese metal stamping manufacturer founded in Tokoname City, Aichi Prefecture, operating for approximately 70–78 years (1947 per firmographics; 1956 per legal filings) with a workforce of approximately 300 employees. The company specializes in complex, high-precision press processing — including ultra-high-tensile material forming (up to 1,800 MPa grades such as SCGA1180), large-scale deep drawing (up to 400mm × 1,000mm), and extreme blanking — delivering precision tolerances of ±1/100mm. Production is integrated end-to-end from die design and development through press forming, welding assembly, painting, and finishing, supported by capital-intensive assets including a 1,200-ton progressive press line, robotic press systems, automated guided vehicles, and fiber laser welding. Operations span three Aichi sites: Tokoname (headquarters/main/die factories), Nagoya-Arimatsu (welding/maintenance parts), and Toyoake (a 10,841 m² facility dedicated to EV press parts, opened 2023).

The company's revenue is generated primarily through B2B contract manufacturing of stamped automotive components — motor housings, EV battery cases, body and chassis structural parts, seat mechanisms, airbag components, and transmission parts — supplied to Japanese automotive OEMs (Toyota and other Japanese OEMs implied through supply chain context) and Tier 1/2 suppliers via long-term direct supply relationships, with a reported monthly shipment volume of approximately 9.3 million units. A secondary revenue stream is the proprietary IoT GO / IoT GO DX software platform (co-developed with Microlink), which is sold externally on a subscription model with 0-yen initial cost, deployed with approximately 30 custom AI models for manufacturing site optimization. A third stream comprises self-developed solar panel mounting hardware (MKU/MKL/AKU series) sold to construction and solar installers. GTM is exclusively direct enterprise field sales with no intermediaries, supported by monthly virtual factory tour webinars, factory tours for manufacturing executives, industry association leadership (President serves as chairman of the Japan Metal Press Industry Association), and earned media in Nikkan Kogyo Shimbun, Chunichi Shimbun, and trade publications.
