Multi bending curved surfaces
Whenever we need to produce curves in sheet metal we have several methods to consider. The overall length of the profile, material type, thickness, radius and production volumes all play a part in this decision. With small components in relatively high volumes constructing a form tool may well be a sensible option. This type of tooling could be mounted in a CNC press brake, power press or if small in a fly press. It would be idea for small brackets with curved profiles.
If however the part had an even radius form, rolling the curve may be a better option. With a range of hand and power rollers in house we often roll curved shapes. Up to 1M wide and a range of materials and thicknesses up to 3mm can be processed. Rolling works best where a consistent radius is required, for instance a semi-circular band. If however a more complex multi-radius curve is required then multi bending is the perfect solution.
Multi bending sheet metal curves
Multi bending on CNC press brakes can be a very flexible manufacturing process. With the ability to create complex shapes with both concave and convex curves within the same piece of sheet metal, multi bending is the method of choice for larger and complex profiles. Being able to adjust CNC programs from batch to batch to suit different material spring back characteristics is perfect. Curves can be checked against laser cut templates to ensure their accuracy.
With no special tooling required multi bending can also be used as a quick way to try out shapes for prototype work before money is committed to expensive hard tooling. More images of curved sheet metal can be found on our Pinterest Boards.
The great thing about all these processes; forming, rolling and multi bending is that we can apply the right one to suit your design and volumes. With a copy of your drawing or CAD data we can explore the options for you and produce a range of prices to suit. Simply send us an enquiry and we will do the rest.
