Abstract: The present invention provides an expansion die for manufacturing containers including a work surface including a progressively expanding portion and a land portion; and an undercut portion positioned following the land portion of the work surface. The present invention further provides a process for manufacturing shaped containers including providing a container stock having a first diameter; expanding at least a portion of the container stock to a second diameter with at least one expansion die; and forming an end of the container stock to accept a container lid.

Abstract: The present invention provides a necking system including a plurality of necking dies each necking dies having an at least partially non-polished necking surface and a non-polished relief following the necking surface. The present invention further provides a method of necking a metal container including providing a metal blank; shaping the blank into a bottle stock; and necking the metal bottle stock, wherein necking includes at least one necking die having an at least partially non-polished necking surface.

Abstract: A method for manufacturing containers including providing a container having a first diameter; expanding the diameter of the container to a second diameter with at least one expansion die is disclosed. Expansion dies can be used to expand the diameter of a container. Multiple expansion dies can be used to gradually expand the diameter of the container without significantly damaging the container. The container can then be formed to accept a closure.
