Press brake forming is a metalworking process where flat sheet metal is bent into a specific shape using a press brake machine. The process involves applying force between an upper punch tool and a lower die, creating precise linear bends in various metal materials and thicknesses. CNC controllers are used for accurate part positioning and consistent results. This technique is ideal for producing parts like U-bends, flanges, channels, and internal bends. The lead time for qualifying formed parts can be as quick as three days.
Adhering to these guidelines for sheet metal forming will help guarantee high-quality results and quick turnaround times for your projects.
| Maximum Bend Length | 47 in. |
| Minimum Qualifying Part Size | 0.05 in x 0.05 in (12.7mm x 12.7mm) for formed parts |
| Maximum Pressing Force | 80 tons |
| Bend Angles | 1 degree ‘kick’ to 135 degrees |
| Bending Output | Linear bends—external and internal flanges |
| Maximum U-Channel Ratio | 2:1 (width:height) |
| Internal Radius Tooling Options | 0.01 in. to 1 in. (standard tooling increments) >1 in. radius bends will be bump formed |
| Offsets | Standard offset tooling sizes |
| Hems | Closed hems up to 47 in., open hems up to 36 in. |
