Impact Extrusion of aluminium

[Thomasmac]

I'm looking for a guru on the impact extrusion of aluminium. It's for a project I'm involved in with regard to the manufacture of Scuba Diving Cylinders. I would appreciate it if someone could point me in the right direction as I'm unfimilia with this type of process.

I know the process is used for making fire extenguishers, if that helps

This process is used in making many high pressure cyclinders, as well as ammunition cartridge casings.
