Question

The problem with moulding equipment in jolt moulding can be avoided by implementing a squeeze method of ramming.

(a) True

(b) False

This question was addressed to me by my college professor while I was bunking the class.

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

Answer 1

Right option is (a) True

The explanation is: In squeeze ramming, a plate smaller than the inside dimensions of the moulding flask is fitted with the moulding sand. Then a uniform pressure is applied by the downward movement of a plate or by the upward movement of the flask itself, so this method avoids the damage to the moulding equipment.
