A foundry is an industrial facility that produces metal castings. Metals are cast into shapes by liquefying them into a fluid, pouring the metal into a mold, and removing or emptying the form material after the metal has solidified as it cools. The most widely recognized metals prepared are aluminum and solid metal. However, other metals, for example, bronze, metal, steel, magnesium, and zinc, are likewise used to create castings in foundries. Foundry processes can be divided into two types – ferrous foundries and non-ferrous foundries i.e. the type of metal they use for casting of the moulds. Ferrous and Non-ferrous metals are distinguished by the presence of iron in the metal. Ferrous metals are defined as those metals that contain iron. Non-ferrous metals do not. Iron and its types like cast irons, grey iron, ductile iron, steel and other iron alloys are the examples of ferrous metals. Whereas Non-ferrous metals include every metal and alloy that does not contain iron, a shor
