Aluminum can be extruded and bent to specified tolerances or to standard dimensional tolerances. Bending a U-Channel . Regardless, for other materials and material thicknesses, bottoming out the punch can be a way to “make it work.” The punch descends to a “less than material thickness” position in the die. An example callout for standard channel would be C12x20.7#. When I bend both sides 90 degrees I get about a 1.5" inch thick channel which works great. Several factors should be considered when choosing which bending process is appropriate for a certain product. From a bending perspective, it’s always best to bend these parts in an annealed state and then temper them to the correct condition.
