Question

Which of the following is the main advantage of using the electromagnetic forming process?

(a) High speed

(b) Low maintenance

(c) Applicable to all materials

(d) No spring-back

I had been asked this question at a job interview.

I would like to ask this question from Electromagnetic Forming topic in division Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer 1

Right answer is (d) No spring-back

Easiest explanation: In the electromagnetic forming process, the metal is loaded and achieve plastic region, which results in plastic or permanent deformation, so that the spring-back associated with the mechanical forming process is completely eliminated because no any mechanical contact is present during the process of metal forming.
