Non Destructive Testing

About the Book: Metal Casting is one of the oldest materials shaping methods known. Casting means pouring molten metal into a mold 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 mold either by breaking the mold or taking the mold apart. The solidified object is called the casting. By this process intricate parts can be given strength and rigidity frequently not obtainable by any other manufacturing process. The mold into which the metal is poured is made of some heat resisting material. Sand is most often used as it resists the high temperature of the molten metal. Permanent molds of metal can also be used to cast products.
