All aftermarket rear axles are done that way after heat treating and it is not the flange that is bent, it is the axle shaft itself. They put them between live centers and spin them with a dial indicator on the face of the flange and then they mash the shaft to bend it between the two ends so the face of the flange runs true.
If you have a way to check the face of the flange for true after you bend the shaft, you can do it just fine. Also why you can't check an axle for true by rolling across a flat surface. The shaft may not be perfectly straight, but as long as the splined section and the face of the flange are in line, it's a good shaft.
