Bend Radius

bend-radius-th-(2).jpgATAS International, Inc. has staff with years of experience that understands the science of various types of proper metal forming.

Factors taken into consideration in part and machine design include:
  • Design of panel or part
  • Type of materials
  • Size and thickness of part
  • Size of bend
  • Bend radius
  • Angle
  • Product end use

ATAS uses the following various types of forming methods:

Bending
  • Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal utilizing press brake among other specialized machine presses.

Folding
  • In folding, clamping beams hold the longer side of the sheet. The beam rises and folds the sheet around a bend profile. The bends beam can move the sheet up or down, permitting the fabricating of parts with positive and negative bend angles.

Wiping
  • In wiping, the longest end of the sheet is clamped, then the tool moves up and down, bending the sheet around the bend profile. Though faster than folding, wiping has a higher risk of producing scratches or otherwise damaging the sheet, because the tool is moving over the sheet surface.

Roll Bending
  • The roll-bending process induces a curve into bar or plate work pieces. There should be proper pre-punching allowance.
