What is Casting?

• Casting means pouring molten metal into a refractory mould with a cavity of the shape to be made and allowing it to solidify.
• The solidified object is called casting.
• Application of casting are cylinder blocks, piston, piston ring, wheels, housing etc.

Benefits or advantages of Casting

Following are the benefits or advantages of Casting:
➨Molten metal can flow in any small section.
➨Any intricate or complex shape can be made which are difficult to be made by machines.
➨It is possible to cast almost any material (ferrous or non-ferrous).
➨Casting is cooled uniformly, so there is no directional properties.
➨Different pouring methods can be employed.
➨The method is used to manufacture very large parts.

Drawbacks or disadvantages of Casting

Following are the drawbacks or disadvantages of Casting:
➨Casting results into poor surface finish.
➨The output has dimensional inaccuracy.
➨Defect arising out of the moisture present during the casting process.
➨Tooling lead time is long compare to machining.
➨Tooling cost is high compare to machining.
➨The design changes are costly and time consuming compare to machining.
