A sheet <a href = "https://www.metalforming-usa.c....om/folders/\"&g bending machine</a> has a folding beam that bends the metal instead of breaking the metal. This decreases surface markings so finished pieces are cleaner looking and painted parts aren’t damaged. Folding/bending machines are more accurate than brakes, which decreases metal waste and time delays in manufacturing and allow for a quicker and easier welding process. A folder has a beam that folds the metal by rotating around the lower beam. Some folders can fold up and down decreasing time and labor by not needing to flip the part over.
