Precise Forming, Repeatable Bends
Bent / Formed Parts
Brackets, Housings, Frames
Metal bending is a sheet metal fabrication process that uses controlled force to deform a flat metal sheet into a desired angle or shape without removing material. A press brake and a suitable set of punches and dies are commonly used to create accurate bends according to the part geometry.
Metal bending can produce simple bends as well as multiple-angle and multi-bend components.
Metal bending forms sheet metal through controlled deformation using a press brake or other forming equipment. Here are the processes of metal bending at 3DSPRO:
Import the CAD file and review the part geometry.
Determine the material, sheet thickness, bend angles, and bend radii.
Select the appropriate bending method, tooling, and machine.
Calculate the bending sequence and optimize the setup.
Position and secure the sheet metal.
Metal bending machine operating.
Inspect bend angles and critical dimensions.
Perform deburring and other secondary operations if required.
Welding or assembly (optional).
Surface finishing (optional).
Quality inspection.
Packing and shipping.
1. Produces three-dimensional sheet metal parts without removing significant material.
2. Can create precise angles, bends, and formed profiles.
3. Suitable for brackets, panels, enclosures, frames, and structural components.
4. Supports a wide range of commonly used sheet metal materials.
5. Can be combined with laser cutting, welding, and surface finishing to manufacture complete parts.
1. Bend geometry is limited by the available tooling, machine capacity, and material properties.
2. Springback can affect the final bend angle and may require process compensation.
3. Very complex geometries may require multiple setups or specialized tooling.
4. Certain materials or thicknesses may require specialized bending equipment and tooling.
