TCDC was founded in Minneapolis, Minnesota in 1919 by Charlie Adams, a pioneer in the die casting industry. The company continued its foundation of family ownership, when a family friend, James Harmon, purchased the company in 1974. In 2005, Doug Harmon became the CEO and sole shareholder .
Today, TCDC operates three IATF 16949:2016 certified US facilities in the Midwest. All locations are within 200 miles of the corporate headquarters of Minneapolis, Minnesota. The second plant, located in Watertown, South Dakota was added in 1989 to handle TCDC's growth; and a third plant in Monticello, Minnesota in 2000 to facilitate TCDC’s entrance into magnesium die casting. In addition to holding IATF certification, all facilities are also certified to the ISO 14001:2015 Environmental Management Standard, and the ISO 45001:2018 Occupational Health and Safety Management System Standard.
In 2017, Doug sold his stock in the company to the employees under an Employee Stock Ownership Plan. This change preserved the culture of family ownership and its foundation of die casting excellence is now driven by its most important asset – it’s employee owners.
