Metalcasting is one of the oldest manufacturing methods known to humankind and a very direct method of producing metal parts. The first castings can be dated back to ancient China in the 4th century B.C.
Through the metalcasting process, molten metal is poured into a mold that matches the final dimensions of the finished product. While all metals can be cast, the most predominant are iron, aluminum, steel and copper-based alloys. Castings range in weight from less than an ounce to single parts weighing several hundred tons.
Over the years, the development of the
metalcasting industry paralleled the American industrial revolution and foundries developed near growing settlements and cities nationwide. As settlers plowed through the American prairie, stronger metals were required to cut through the turf, shoe horses, create buggies and eventually lay the rail tracks that opened the west. Today, iron castings are found in almost all durable goods and machinery. From the machines that make the vehicles we drive to the materials found in our homes, we live and travel on cast iron.
