Question

In cold forming process, the fuel cost is very less as compared to that in the hot forming process.

(a) True

(b) False

This question was posed to me during an online interview.

My question is from Behaviour in Metal Forming topic in division Forming Process of Casting-Forming-Welding II

Answer 1

Correct option is (a) True

The best I can explain: In cold forming process, not much heating is required, which generally saves the fuel costs and permits higher production rate of the metal parts. And in hot forming process, the metal is subjected to very high temperature that requires lot of fuel to generate enough heat, which increases the overall cost of the hot forming operation.
