Metal Casting

Metal casting is described as a manufacturing process in which a mold cavity is produced by sand, and molten metal is filled inside a mold cavity. The desirable shaped object is achieved after the solidification of molten metal. Large metal objects like machine beds, motor bodies, and others can easily be manufactured using metal casting. The place or shop where metal casting is performed is called foundry.
