Metal casting is the process of making objects by pouring molten metal into an empty shaped space. The metal then cools and hardens into the form given to it by this shaped mold. Casting is often a less expensive way to manufacture a piece compared with machining the part out of a piece of solid metal. There are many metal casting methods to choose from. What type of casting is most efficient depends on the metals used, the size of the run, and the complexity of the casting.
In engineering industries, most of the components are made by ferrous and non-ferrous metals such as iron, steel, aluminium, etc. Some of the complicated shapes may not be produced on the components with conventional machining processes. Metal casting processes are used to manufacture components having complicated shapes.
