Question

In the mechanized foundry, the process of breaking gates may crack or damage the castings parts.

(a) True

(b) False

The question was asked at a job interview.

This key question is from Processing Steps in Mechanized Foundry topic in chapter Foundry Mechanizations of Casting-Forming-Welding I

Answer 1

The correct choice is (b) False

Easy explanation: In the mechanized foundry, the gates are break off from the castings without any subsequent damage to the casting part itself. This is achieved by redesigning the gates practically from all of the patterns so that the cross-section of the gate reduces enough to enable it to break off at that point without damaging the casting.
