Introduction • Casting is one of the earliest metal shaping methods known to human being. • It generally means pouring molten metal into a refractory (resistant to heat) mould (a shaped cavity used to give a definite form to molten metal) with a cavity of the shape to be made, and allowing it to solidify. • When solidified, the desired metal object is taken out from the refractory mould by either breaking the mould or taking the mould part. • The solidified object is called casting.
