Abstract
A system and method of manufacturing a metal vessel may include providing a preform being formed of a work hardened metal. The preform may have an open portion, a closed end portion, and body portion. A multiple segment mold may be closed around the preform. The preform may be blow molded by causing a step-like change in pressure within the preform to cause the preform to take a shape defined by the mold. The molded preform may be removed from the mold.
