A new process of metal casting has been developed, considered as on of the most challenging technologies ever made. Making progress now a day are the trend of most technology issues. For the fact that the new metallurgy casting of metals are the product of well-developed form of technology. Metal castings are fundamental building blocks which imply pouring of a ‘liquid’ material into ‘A Mold’ containing a desired shaped hollow cavity, and then made to solidify.These are the following steps in metal casting:
1. The Melt
2. Entertainment
3. Flow
4. The Mould
5. Solidification Structure
6. Gas Porosity
7. Solidification Shrinkage
8. Linear Contraction
9. Structure, Defects and Properties of the finished Casting
10. Processing
11. Environmental Interactions
