manufacturing process of cast iron castings

2018113&ensp 0183&enspcast iron begins its life as pig iron which is remelted and often combined with large amounts of scrap iron and sometimes with steel. contaminants are removed from the melted pig iron and the iron once melted is then cast. casting is the process of pouring the iron into a mold thus giving it a shape.
