Two methods can press brakes bend steel. The first is bottom bending, where the ram presses the metal to its bottom. Bottom bending allows for precise bends, and less reliance on the machine's press brake. Each tool has its limitations. They are designed to create a particular bend and you will need a different one for each angle. The bottom of the die and the ram are separated by an air pocket when air bending occurs. This allows for the operator to account for any material spring back. These types of dies need to only be changed if there is excessive material thickness. Air bending has a drawback. Because the thickness of the material can affect the accuracy, the ram needs changing accordingly.
Flexible and reliable bending performances with the patented HEXA (r) frame – all this in a cost-efficient package
The PA Plus series combines functionality and versatility in one powerful package. The PA Plus series is designed for a large array of accessories for a customizable solution.
Our press brake machines are backed by Standard Industrial's reputation as a durable and repeatable machine. This gives them an advantage over other models.
Early generations of press brakes only had one axis of motion to make bends. They were much more limited compared to modern machines with 12 or more programmable axes of movement. Modern press brakes are highly precise and create graphical representations of the end result to aid the operator. Newer computers have dramatically reduced the setup time as well. They’re able to quickly calculate optimal settings based on materials being used, its dimensions, and the desired results. These calculations used to be done by hand, back in the day.
These machines are efficient and fast, and run more consistently than their predecessors.
The next step is to determine the characteristics that will be used to calculate the part bend. For example:
This method offers high levels of precision and angular accuracy. This method is ideal for sheet metal with a thickness of more than 2 mm.
The CNC technology system-the Computerized Numeric Control is used to design our Single Cylinder and Dual Cylinder Hydraulic Press Brakes. This system uses a blast system to remove rust from the work-piece's surface. Our range of dual bending machines are completely electrically powered because they run on Servo Electric systems. They don't require any hydraulic oiling, and their energy consumption is very low.

Air bending is done by bending sheet metal at the ends of the punch and 2 edges of V. This type of bend also creates a spring effect in the work piece. Because the bending force in this case is weaker, the metal sheet can spring backwards as if it were elastic.
Hydraulic press brakes make heavy-duty work possible and can be tailored to address the most varied customer forming needs, including long length, tandem and high tonnage.
This revolutionary tool changer gives press brake operators real-time information to help them perform better.
A Mitsubishi automatic changer (ATC), fitted with a press brake is a unique piece of equipment.
Semi-trucks use compressed air for their brakes instead of hydraulic fluid. Semi-trucks have a lot of weight so they need air to brake.
The press brake is, in reality, one of the most difficult machines to master in the trade. Every sheet metal operation needs to bend.
Crowning is the method by which press brakes correct for deflections in both the upper beam or lower bed when pressure applies. There are different methods, depending on the model and make of the press brake.

A hydraulic press crushed a worker to death in an industrial accident. Two workers were placing materials under hydraulic presses. An online video of the incident shows this. While the victim was fixing the materials, the worker controlling the machine turned the engine on.
