Homestead Products began in 1965 as Homestead Tool & Machine. The business was started to manufacture molds and tools for the manufacturing of refrigerator components. In 1970, Homestead Tool added another dimension by creating another business known as Homestead Foundry. This business was created to provide the castings for the tools being manufactured by Homestead Tool and later expanded into the automotive industry. Also in the 1970s, the Homestead Companies began producing for AEDC government contracts, manufacturing wind tunnel blades and spacers. HPI, or Homestead Products, began business in 1982 by securing an original equipment manufacturer contract with General Motors, which it maintained through 1997, for the manufacture of pickup truck bed liners. HPI manufactures a variety of other products, such as egress windows for residential construction, hot tubs, children's playground slides, canoes, rear seat modules for police cars and other miscellaneous items. Homestead Products is headquartered in Coleman, Mich.
