Question

Which machine molding process will give uniform strength throughout the mold?

(a) Sand slinging

(b) Squeezing

(c) Jolt and squeezing

(d) Jolting

I had been asked this question during an online interview.

The doubt is from Methods of Ramming Mold Boxes topic in division Mold and Mold Making of Casting-Forming-Welding I

Answer 1

Right answer is (a) Sand slinging

For explanation: In sand slinging, we will obtain uniform strength throughout the mold because localized ramming of sand takes place because of throwing the small-small amount of sand into the mold box at the same amount of force. But in other processes strength will be more at the top or bottom or middle.
