Abstract
A system and method of manufacturing a metal vessel may include inserting a preform into a mold that includes multiple segments, the preform being a work hardened metal. A pre-pressure may be applied to the preform at a first pressure level. The multiple segments of the mold may be closed, and the pressure being applied to the preform may be increased using a step function to a second pressure level after the mold is closed to cause the preform to take a shape defined by the mold.
