Abstract
A system and method of manufacturing a metal vessel may include providing a preform being formed of work hardened aluminum. The preform may have an open portion, a closed portion, and body portion. A multiple segment mold may be closed around the preform. The multiple segment mold may include at least one projecting portion operative to partially deform the preform while closing the mold. 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 when the mold is in the closed position. The molded preform may be removed from the mold.
