MINO Industry Tochigi Co., Ltd.

MINO Industry Tochigi Co., Ltd. (美濃工業栃木株式会社) is a Japanese manufacturer specialising in aluminium die casting. According to its official website, the company was founded in 1934 (Showa 9) and is headquartered in Oyama, Tochigi Prefecture, where it operates two sites that together cover the full manufacturing chain from sales and planning through design, production planning, production and shipping. Rather than being a satellite plant, the Oyama operation also houses head-office functions, so a wide range of business activities are carried out locally. The company's core competence is die casting — pouring molten aluminium alloy into a mould and cooling it to form parts — and it positions this technology as a way of supporting leading manufacturers across several industries. Its product range includes engine parts for automobiles and trucks, large components such as escalator steps, motor-case parts for hybrid and electric vehicles, and cover parts for outboard motors. It also works with DC (die casting), GDC (gravity die casting) and sand-mould parts, and has developed in-house techniques such as a vacuum die-casting method that draws air out of the cavity to reduce pressure during casting. MINO Industry Tochigi describes its corporate philosophy around the motto "quality assurance, ingenuity, and harmony of people" (品質確保・創意工夫・人の和), to which it adds environmental, safety and security commitments. It states an ambition to become a global leading company that delivers safety and peace of mind to customers through manufacturing that respects the global environment and local community, responding to ever-higher demands for high-strength lightweight parts, high quality and ultra-short lead times. Compliance, environmental policy and SDG-related activities — including ISO 9001 and ISO 14001 certification, energy-saving equipment, aluminium recycling, LED lighting, foreign technical intern trainees and re-employment of retirees — are presented as part of this agenda. The company is a regional employer in Tochigi, recruiting new graduates and mid-career staff and running company information sessions and internships with local institutions and universities. Its public communications emphasise a one-stop, integrated quality-management approach spanning development, production preparation, production, delivery and after-sales service.

MINO Industry Tochigi Co., Ltd. traces its origins to 1934 (Showa 9), when the company was founded, according to the corporate profile published on its recruitment pages. Over the decades it developed into an aluminium die-casting manufacturer, building its operations around Oyama in Tochigi Prefecture, where it today runs two sites that together handle the entire manufacturing process — sales, planning, design, production planning, production and shipping — and also host head-office functions. The company's technical development has centred on die casting, the process of pouring molten aluminium alloy into a mould and cooling it to form parts. It works across DC (die casting), GDC (gravity die casting) and sand-mould parts, and has developed its own vacuum die-casting method, in which air is drawn out of the cavity to create a near-vacuum and reduce pressure during casting. Its production lines use robots for steps from casting through gate removal and deburring, an approach the company presents as a way of saving labour and stabilising quality. Product-wise, MINO Industry Tochigi has served the automotive and truck industries with engine parts, and has extended into large components such as escalator steps, motor-case parts for hybrid and electric vehicles, and cover parts for outboard motors. It describes its role as supporting leading manufacturers in each of these industries, and frames its offer around integrated quality management from development and production preparation through production, delivery and after-sales service. Institutionally, the company has adopted the corporate motto "quality assurance, ingenuity, and harmony of people" (品質確保・創意工夫・人の和), and has added environmental, safety and security commitments. It states an ambition to become a global leading company delivering safety and peace of mind through manufacturing that respects the global environment and local community, and to respond to demands for high-strength lightweight parts, high quality and ultra-short lead times. Its environmental and sustainability activities include ISO 9001 and ISO 14001 certification, energy-saving and high-efficiency equipment such as air compressors and aluminium melting furnaces, LED lighting and lights-out practices, recycling of aluminium alloy, cardboard and machining chips, acceptance of foreign technical intern trainees, active re-employment of retirees to pass on skills to younger workers, and local supplier use. As a regional employer it recruits new graduates and mid-career staff and engages with local educational institutions, including company information sessions and on-campus seminars.
