? Casting is a manufacturing process by which a 
liquid material is usually poured into 
a mold, which contains a hollow cavity of the 
desired shape, and then allowed to solidify. 
? The solidified part is also known as a 
casting, which is ejected or broken out of the mold 
to complete the process.

? Casting materials are usually metals.
?Almost all metals can be cast.
? Casting is most often used for making complex 
shapes that would be otherwise difficult to make 
by other methods.
