Which machine bends plate or sheet metal by having a punch pressed into a die?

• A. Press brake machines
• B. Punching machines
• C. Water jet cutting
• D. Laser welding

Answer: (A)

Bending plate or sheet metal by pressing a punch into a die is done with a press brake. In this setup the sheet sits on a die and a punch on a moving ram pushes down into it, deforming the metal to create a bend. The die’s opening and the punch shape determine the bend angle and radius, and tooling can be swapped to produce different bends. This is different from punching machines, which push a punch through the sheet to cut holes; water jet cutting uses a high‑pressure jet to slice material, and laser welding joins pieces with a laser rather than forming bends.
