hydroforming

[¦hī·drə‚for·miŋ]
(chemical engineering)
A petroleum-refinery process in which naphthas are passed over a catalyst at elevated temperatures and moderate pressures in the presence of added hydrogen or hydrogen-containing gases, to form high-octane BTX aromatics for motor fuels or chemical manufacture.

In addition to a hydroforming die, you'll need a special shell holder without a priming hole, a handful of spent primers, a bit of case lube, a container of water and a method of filling cases without spilling.
hydroforming applications, entails loading a tube into a hydroform die and fixturing the die assembly into a hydroforming press.
Monforte, II, Burke, and Madden shaped a composite with two stages: (a) consolidating and shaping the working material into a pre-form shape using a dynamic hydroforming process with a rigid, male-shaped tool and a non-rigid, female-shaped tool without heating, and (b) further consolidating and shaping the working material into the final shape using a rigid forming tool with heating.
