Question

Wire drawing process is almost similar to deep drawing process.

(a) True

(b) False

I had been asked this question by my school teacher while I was bunking the class.

My question is from Classification of Metal Forming Processes topic in section Forming Process of Casting-Forming-Welding II

Answer 1

Correct answer is (b) False

The explanation: Wire drawing process is quite different from deep drawing process. In wire drawing, metallic bar is pulled to form wires, while in deep drawing process; a flat metal sheet is converted into a concave shape part. This operation is basically performed by stretching the metal for which a blank-holder is used to clamp the blank on the die, and then a punch is used which pushes the metal sheet.
