About Diamond Electric Mfg. Corp
Diamond Electric Mfg. Corp. traces its roots to 1937, when Inosuke Tomita founded Diamond Electric in Japan. The company established its U.S. presence in 1990 with Diamond Electric United States (DEUS) in Dundee, Michigan, led by first president Nobu Hashimoto. In 1996, ground broke on a new plant in Eleanor, West Virginia, where mass production of ignition coils began in 1997. The Eleanor facility held its grand opening in 1998 and has since expanded multiple times. Today the corporate office remains in Eleanor, while a sales and design center operates in Farmington Hills, Michigan, near Detroit’s automotive hub. The company designs, manufactures, and distributes automotive electrical components, specializing in ignition coils. Its capabilities span design engineering, research and development, manufacturing, and thorough product testing. Multiple U.S. locations provide manufacturing, sales, and support for global OEM customers. The Eleanor plant handles high-volume coil production, while the Farmington Hills center focuses on design and customer collaboration. Diamond Electric serves three primary customer groups: OEM automotive manufacturers, service-part retailers, and DIY installers. It has earned quality awards from major automakers, including a President’s Product Quality Award from Subaru of Indiana Automotive in 2004. The company also supports community initiatives in Putnam County, West Virginia, where it was named Corporate Citizen of the Year in 2005. The business is guided by a philosophy that prioritizes trust, superb quality, and the happiness of all stakeholders. Core values include customer focus, community involvement, integrity, teamwork, open communication, and safety. Diamond Electric emphasizes partnering with stakeholders as the key to the future, delivering products on time and defect-free through dedicated teamwork and constant improvement.
