Shaping of metal by squeezing them in between two or more dies in order to obtain desired shape is done by?

• A. Forging
• B. Welding
• C. Grinding
• D. Chipping

Answer: (A)

Shaping metal by compressing it between dies to force it to fill the cavities and take the desired form is forging. This process uses high pressure, often with hot metal, to plastically deform the workpiece so it flows into the shapes of the dies. Open-die forging uses basic shapes and multiple steps, while closed-die (impression) forging uses dies with cavities to produce near-net or final dimensions, benefiting from grain flow that enhances strength and toughness.

Welding joins pieces; grinding removes material to smooth or finish surfaces; chipping also removes material. These are not forming processes like forging.
