The invention provides a method and a system for manufacturing a container, the method includes supplying a container having a closed bottom, a sidewall with an interior diameter and a height, and a lower body between the closed bottom and the sidewall, the lower body having a profile, into a die system comprising a container base holder having an opening with a diameter to receive the closed bottom of the container; and an interior having a lower body profile, and one or more rigid metal expansion dies, wherein at least one rigid metal expansion die of the one or more rigid metal expansion dies comprises a tip having lower body profile that cooperates with the lower body profile of the container base holder, wherein the lower body profile of the container base holder and the tip are different than the profile of the lower body of the metal container; positioning the closed bottom of the container into the opening diameter of the container base holder; moving one or more rigid metal expansion dies to travel axially within the container to radially expand the interior diameter of the sidewall to a larger interior diameter by the axial travel of the one or more rigid expansion dies, shorten the height of the sidewall and reform the profile of the lower body of the container, wherein the larger interior diameter is uniform along the height of the sidewall. |
