Sheet Metal Bending Services

Sheet Metal Bending or Press Braking is the metal fabrication method of manipulating metal into an angular shape such as U-Shaped, V-Shaped, Channel – Shaped parts. This fabrication occurs when the workpiece has a sufficient force applied to create a lasting bend. Die bending, folding, edging, or flanging are other names for this fabrication process. 

There are two typical methods of operation, Air Bending and Bottom Bending. Air Bending drives the punch into the sheet metal to a specific angle bend. The press brake has a punching tool, and a V-opening bottom die. The punch presses the material into the V-shaped bottom die. This creates three points of contact, the tip of the punch, one on each side of the top of the V opening. These points of contact determine the inside bend radius, and the depth is used to define the angle bend. As a result, air bending is more flexible and quicker and provides less surface damage. 

Bottom bending, also known as bottom pressing or striking, uses a bottom V-Shaped die and a punch but bends the material by bringing these elements together. The die's angle determines the final angle of each workpiece. This method requires more pressure and can leave tooling marks.
