During 1955, the Central Engineering Works (established in 1917 in Johannesburg) began the erection of a plant in Duncanville in Vereeniging for the manufacture of castings. In 1970, the Nordberg Manufacturing Company aquired the Central Engineering Works and consolidated the factory and foundry operations in Vereeniging.
In 1988, due to international sanctions, a local management consortium gained control of Nordberg SA. Then in 1993 when sanctions were lifted, the Rauma Group, Metso’s predecessor, acquired the company.
Metso Mineral’s 125,000 m2 works in Vereeniging employs 320 people operating the factory’s ferrous and bronze foundries. These are able to produce castings as large as 18 tons. However, it is far more than just a foundry, having extensive machining and assembly facilities for the manufacture of cone crushers as well as the manufacture of components for G cone crushers and jaw crushers that are assembled abroad. It is the only company in the country that manufactures a full range of communition, pyro metallurgical and mineral processing equipment.
