Ever wondered how heavy steel plates can be bent so easily by a press brake?
The secret lies in the powerful force generated by hydraulic or servo systems, pressing the plate into upper and lower dies to achieve accurate bending.
What looks like a simple fold is actually the result of mechanics, die design, and advanced CNC technology.

Today let’s talk about the basic principle of a press brake—why can it bend steel plates?
A press brake works by using upper and lower dies. With hydraulic or servo systems generating powerful force, the steel plate is pressed into the die to create a bend.
In simple terms, the upper die moves down, pushing the sheet into the V-shaped groove of the lower die, and the plate bends according to the die’s angle.
The bending angle depends on the die shape, sheet thickness, and the applied force.
Modern CNC press brakes also use automatic compensation to minimize errors, ensuring precise results every time.
So, while it looks like “just folding steel,” in reality,it’s the result of mechanics, die design, and advanced control technology working together.
