Point well taken.

There are multiple dimensions to manufacturing efficiency, though, right? I have no appreciation for the cost of a couple dies and a machine for stamping versus the cost of a CNC break with one die, but it may play a part based on the number of units they think they will sell. (1,000? 10,000? 100,000?)

If starting with super hard cold rolled steel, it’s most likely impossible to “stamp” using traditional progressive stamping dies. The deformation has to exceed the final shape and via springback the final shape is produced.

Springback is possible on a press brake when folding along a single straight line. If panel needs a 30 deg bend, then bend it to 40, and it pops back 10 when off the press brake. As an example.

That quickly gets impossible to do when you start bending around complicated 3D contours.
