How does metal bending work?

Back to faq

A press brake is a specialized machine used to bend a sheet of metal, such as aluminum, into a specific angle, shape, or curve. This machine enables the bending of a single sheet, eliminating the need to weld two plates together. However, the aluminum to be bent must meet certain requirements (see ‘Can you bend aluminum?’).

The press brake consists of an upper die and a lower die. The sheet to be processed is placed between the upper and lower dies. The upper die presses the sheet against the lower die, causing the sheet to deform. The upper die is in the shape of a ‘blade,’ while the lower die has a V shape, commonly referred to as the V-groove.

Different dies can be used in a press brake, depending on the specific bending operation required on the sheet.

Advantages of a press brake:

  • Unlike a folding machine, the sheet is not clamped down in a press brake, which saves time during the bending process.
  • A press brake can create a bend in a single sheet, avoiding the need to weld two plates together. Welding requires additional labor and not every sheet is suitable for welding.
  • A sheet that is bent using a press brake looks very neat and does not require post-processing, unlike welding, which often requires additional finishing.

Press brakes come in various sizes and lengths, and there are different types of dies available, allowing sheets to be deformed in various ways.

Using a press brake, we can bend various sizes and types of aluminum into different angles. Bending aluminum sheets, especially when multiple angles need to be applied to a single sheet, requires the skills of a professional.

Our skilled and enthusiastic team ensures that the machine is correctly set up and that the sheet bending process is carried out smoothly.
