Question

A gating system can allow sudden or right angles.

(a) True

(b) False

This question was posed to me during an interview for a job.

This interesting question is from Principles of Gating and Risering in section Concept of Gating and Risering of Foundry and Forging

Answer 1

Correct option is (b) False

To explain I would say: Since the way in which the liquid metal enters the mold has a decided influence upon the quality and soundness of casting, the different passages for the molten metal are carefully designed and produced. Hence the sudden change is direction is not allowed.
