How to choose a press brake machine in China?


A press brake is a machine pressing tool for bending sheet and plate material, most commonly sheet metal. It forms predetermined bends by clamping the workpiece between a matching punch and die.

The bottom tool is mounted on the table, with the top tool mounted on the upper beam.

The most important factors when purchasing a press brake are the tonnage and bending length. These specifications are determined by the size and thickness of the material you will bend.KRRASS Hydraulic Press Brake 40 ton | NC Press Brake Machine WC67K-40T 1600  for Steel Bending - YouTube

Knowing your application in advance and planning accordingly will help you to make the best decision.


The press brake’s bending force, known as tonnage, determines how much pressure can be applied by the punch during a bend. Higher tonnage allows for bending thicker and harder metals, and lower tonnage is most appropriate for thinner metals.

Bending length

The bending length of a press brake is the maximum possible length of a metal sheet that can be bent.

If you have a very small press brake with 4′ bending length, you won’t be able to bend a 6′ piece of sheet metal because it would be too long. You want to get a Press brake with a bending length that is slightly larger than the length of sheets you will be bending.
