Processing Method

Feed bending (a.k.a. “step bending” or “bump bending”) will be used to process these bends, so there will be die marks left in the part as shown below:

Lead Time

  • Without surface treatment: ~7 days
  • With surface treatment: ~9 days
  • *Expedite delivery option is unavailable for Large Radius bend parts

Production Example

  • Plate thickness: 0.063″ Size: 9.84″ x 6.77″ x 5.59″
  • Material: 5052 Aluminum
  • Surface treatment: Clear Anodize

Common Errors and Solutions

If the model ends in a radius, an Automatic Quotation failure will occur. (Figure 1). Be sure to provide a flange at both ends of the bend. (Figure 2).

*Please model the flanges according to our table on Minimum Bending Height for Large Radius Bending.
