Metal bending covers techniques of shaping either a flat or a structural metal part at an angle, curvature, or channel. Press brake bending is the most popular technology, employing a punch and die to apply pressure on metal sheets. Roll bending is applied for mild bends and large curved lengths of sheet metal or structural beams. Air bending provides flexibility with reduced tools because it does not compel a full sheet into a die. Bottoming gets more accurate results in thicker materials because it uses exact die angles. V – bending is also well spread and appropriate for most common uses. Every procedure is picked depending on the material’s thickness and the required quality.
