System and method for forming a metal beverage container using blow molding

摘要

A system and method of manufacturing a metal vessel may include providing a preform formed of a work hardened metal that includes an open portion, a closed end portion, and body portion. The body portion of the preform may be preheated in a manner that limits heat being applied to the open portion and closed end portion of the preform. The preheated preform may be blow molded.

1. A method of manufacturing a metal vessel, said method comprising:
providing a preform being formed of a work hardened metal, the preform having an open portion, a closed end portion, and a body portion, the preform having a radius that is up to approximately 45 percent less than a maximum radius of a mold; preheating the body portion of the preform in a manner that limits heat being applied to the open portion and closed end portion of the preform; inserting the preheated preform into the mold that includes multiple segments; closing the multiple segments of the mold; blow molding the preform to cause the preform to take a shape defined by the mold; and removing the molded preform from the mold.
