What is casting and how it's made?

What is Casting?
Casting involves pouring molten material into a prepared cavity On which solidification the metal takes the form of the cavity.

CASTING APPLICATIONS:
⦁ Complex and Intricate shapes
⦁ Near net shape
⦁ Large hollow shapes
⦁ Low scrap
⦁ Relatively quick process
⦁ No limit to size
⦁ Reasonable to good surface finish
⦁ Some metals and alloys only by casting
 

STEPS INVOLVED IN CASTING:
⦁ Melt metals

⦁ Pour / force liquid into hollow cavity (mold)

⦁ Cool / Solidify

⦁ Remove the solidified body
                                   

⦁ Fettling/Cleaning

⦁ Finish
⦁ Inspection
