A casting is a metal object produced by solidifying molten metal in a mold. The shape of the object is determined by the shape of the mold cavity. The casting process, also known as founding, involves melting metal and pouring it into the mold cavity, which is close to the final dimensions of the finished form. Many types of complex objects ranging in size from a few grams to thousands of kilograms are produced in a metal casting facility. Castings are produced by

various casting processes such as sand, permanent mold, investment, and lost foam. While all metals can be cast, the most predominant are iron, steel, aluminum, copper, magnesium, and zinc-based alloys. The science of treating the molten metal and designing the molds for smooth flow of molten metal into the mold cavity to minimize air entrapment are essential parts of casting technology to produce premium quality cast components.

CHAPTER PRELIMINARIES 

Cast products are different from wrought products. The former are obtained when molten metal solidifies in a desired form. By contrast, wrought products start as cast ingots that are then thermomechanically shaped by different processes such

as forging, rolling, and extrusion. In terms of value and volume, metal casting ranks second only to sheet steel in the metal producing industry.
