Hydraulic pressure brakes, which use hydraulics to press the ram downwards instead of relying on mechanics, apply pressure via hydraulics. You can have several cylinders and give you more control over your bend. The end result is a customizable, precise bend. However, hydraulic press brakes also have their limitations. They can't exceed the tonnage they are rated at. They may be more flexible if your project demands flexibility.
The motor within a mechanical press brake works by turning a large flywheel. The motor spins a large flywheel at high speed. The flywheel is controlled by the machine operator through a clutch. This sets the other parts in motion to bend metal. The mechanical press brake is simpler, especially in terms of its electronics. This makes maintenance and operation much easier. The mechanical press brakes can handle tons up to three times their intrinsic rating. Mechanical press brakes have one major drawback: the ram must go through a complete cycle once it is engaged. This cannot be reversed. This poses safety risks if an operator makes a mistake or places limitations on the machine. The possibility that the press brake could become locked if too much ram travel is one potential danger.
