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.
Unique technology that delivers high-quality, efficient results to all press brake operators.

Air bending uses the punch's end and the V's edges to allow sheet metal to bent. This type bending also has a springback effect. Because the bending forces are weaker, the sheet of metal will bounce backwards much like an elastic once the punch has been removed.
Bottom bending is when the punch curves the sheet of metal with a higher force than air bending. This reduces, or even eliminates, the spring back effect that is commonly associated with airbending. Cold forging is then performed at the bottom.
The machine runs on a double-axis back gauge system. It can also perform automated bending step calculation. These servoelectric Press Brakes are precise and easy to use.
Generally, the tonnage of a Hydraulic Press Brake is also known as the Press Capacity and is what determines the size of the work-piece that can be processed on the Press Brake and the unit of force measurement which is a press brake can deliver and is what bends work-pieces into desired/specific degrees. The tonnage range of our Press Brakes is between 30 tons to 3000 tons while the bed lengths begin at 4 feet and ranges up to almost 30 feet.
All of these outstanding machine capabilities are combined with industry-recognized service (we average 2 and 1/2 service technicians for every salesperson), a well-staffed emergency number, and a parts division that will blow you away. If your initial investment involves tooling up your presses brake, we also have that covered. We are Wila and Wilson certified tooling professionals with the tools that you need.
The bending angle must be adjusted according to the metal springback and the margin must also be calculated. For example, a 90deg bend requires that the punch be lowered to 85deg.
There are two ways press brakes can bend metal. The first is called bottom bending because the ram will press the metal to the bottom of the die. Bottom bending results in highly accurate bends and relies less on the press brake machine itself. The downside is each tool is they're made to create one specific bend, so you’ll need to purchase a new one for every angle you want to make. Air bending leaves an air pocket between the ram and the bottom of the die. This allows the operator to accommodate for any spring back the material might provide. These types of dies only need to be changed if the material’s thickness is too much. Air bending’s drawback is the accuracy of the angle is affected by the material’s thickness, so the ram needs to be changed out accordingly.
It is a unique technology that allows press brake operators of all skill levels to produce high quality, efficient results.
It is said that the "little guys" sometimes punch higher than their weight classes. Our small, 4-foot press brake is an example of this. The compact bender includes a CNC-controlled X-axis back gauge, tangs capable of accepting euro or american tooling, an LED rear working light and two front sheet supports that slide with a linear rail. There is also a dual palm/foot station equipped with a selector switch. This small, powerful and precise press brake packs a punch.
According to the metal springback, you must adjust the angle of the bend and calculate the margin. So, for example, a 90deg bend must be bent, the punch must be reduced to 85deg.
The use of press brakes is common in sheet metal and production plants in many areas, including automotive and aeronautic.
The press brake is, in reality, one of the most difficult machines to master in the trade. Every sheet metal operation needs to bend.
