5. By implementing mechanization in vacuum moulding, it forms better castings with good reliability.
6. In the mechanized foundry, rubber coated chills are used for supporting the cores in the mould system.
7. The transportation cost of casting is generally less as compared to the cost of mechanization.
8. In mechanized foundry, rubber conveyor cannot be used for long time during production of castings.
9. Mechanization also standardizes the working and equipment used in the production of castings.
