Celebrating Nearly 100 Years in Business!
Twin City Die Castings Company is one of North America’s oldest die casting companies. TCDC was founded in 1919 by Charlie Adams, a pioneer in the die casting industry. The Adams family owned Twin City Die Castings until 1974, when a family friend, James Harmon, purchased the company. Ownership of TCDC passed from Jim to his three son’s Steve, Doug, and Mark in 1979. The company grew as an industry leader in the 1980’s and 90’s under Steve’s leadership as CEO, Doug as CFO and Mark as Vice President. In 2005, Doug Harmon became CEO and sole shareholder of the company. In 2017, Doug Harmon decided to sell stock to the employees under an Employee Stock Ownership Program. Even with this change, Doug’s active management of the company continues to this day as Chairman of the company.
