• Metals difficult to be shaped by other manufacturing processes may be cast (Ex. Cast Iron)
• Best for mass production
• Complex shapes can be manufactured
Disadvantages of Casting

• Dimensional accuracy, surface finish and the amount of defects depends on the casting
process
• Allowances required
Applications of Casting
• Transportation vehicles(Ex. engines)• Machine tool structures.
• Turbine vanes
