Metal Casting Process

Metal Casting Process:-
Metal Casting is one of the oldest materials shaping methods known. Casting means pouring molten metal into a mould 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 mould either by breaking the mould or taking the mould apart. The solidified object is called the casting. The process is also called foundry.
Advantages:-
 Any intricate shape can be produced.
 Possible to cast both ferrous and non ferrous materials
 Tools are very simple and expensive
 Useful for small lot production
 Weight reduction in design
 No directional property
Limitations:-
 Accuracy and surface finish are not very good for final application
 Difficult to remove defects due to presence of moisture
Application:-
Cylindrical bocks, wheels, housings, pipes, bells, pistons, piston rings, machine tool beds etc.
