There must be a word for the opposite of swaging.

Crimping?

Oddly, the definitions I've seen for swaging all refer to reducing the
diameter, but I've always known swaging to be used to refer to
increasing or decreasing the diameter. If you want to specifiy which,
simply using swaging-up or swaging-down.
