forging process- how to use forging process to produce a bicycle hub?

Answer 1

I would start with tubular material which would drop in a split die for forming both sides, the forging head would form one side, squashing it out to shape, then the die would be lifted and turned on to a backing die that would support the first flange while the forging head formed the second flange. The split die would then be lifted out of press, opened, dropping out the hub, and returned to the press to receive another tube.
