Question

By implementing mechanization in vacuum moulding, it forms better castings with good reliability.

(a) True

(b) False

This question was posed to me during an internship interview.

The doubt is from Processing Steps in Mechanized Foundry in section Foundry Mechanizations of Casting-Forming-Welding I

Answer 1

The correct choice is (b) False

The best I can explain: Vacuum moulding is very different from other types of a moulding process. In this method, water is not used in mould mixture that reduces chances of defects in the castings. But, the processes involved in vacuum moulding are very slow and this method cannot be adaptable to mechanization.
