Mound Metalcraft began making metal toys soon after its founding in 1946. In 1955, the company changed its name to Tonka Toys. The company introduced the popular "Mighty" line of model construction vehicles in 1964. Although the metal trucks earned a reputation for toughness, plastic began to replace steel in the toys' construction in the 1980s. Hasbro purchased the Tonka company in 1987.
