The present invention relates generally to forming a threaded neck in a metal bottle manufactured by a process known as impact extrusion. More specifically, the present invention relates to methods, apparatus and alloy compositions used in the impact extrusion manufacturing of containers and other articles with sufficient strength characteristics to allow threading the container necks to receive a threaded closure on the threaded neck.

A trimmer assembly for removing portions of sidewalls of cans is provided. The trimmer assembly includes a chute configured to receive the removed portions of sidewalls of cans. The chute includes an angled extending wall configured to prevent removed portions of sidewalls of cans from travelling past the chute without entering the chute without interfering with motion of the cans.

A shaped metal container comprising less metal than prior art shaped metal containers while still able to handle sufficient axial load and undergo shaping processes, including necking, without wrinkling, buckling, collapsing or other physical defect is disclosed. Processes for shaping a metal container having a sidewall of variable thickness, wherein a portion of the sidewall having a variable thickness is shaped using a die or dies are also disclosed.

An alignment assembly for a press assembly is provided. The alignment assembly includes a number of alignment elements. The alignment elements include a number of moving alignment elements. The moving alignment elements are coupled to an upper tooling assembly that moves between a first and second position. As the upper tooling assembly moves, the moving alignment elements move between a first position and a second position corresponding to the upper tooling assembly first position and a second position. The moving alignment elements are structured to move the shell from the initial alignment position to an intermediate alignment position. Thus, as the upper tooling assembly moves from the first position to the second position, the moving alignment elements contact a shell and move the shell from an initial alignment position to an intermediate alignment position.

Processes for shaping a metal container having a sidewall of variable thickness, wherein a portion of the sidewall having a variable thickness is shaped using a die or dies are also disclosed.

A method of forming a metal container comprises: curling outward a top edge of the metal container to form a curl and expanding a diameter of a first section of the metal container to form a first expanded section; wherein at least part of the first expanded section is below the curl. In some embodiments, the steps of curling outward a top edge of the metal container to form a curl and expanding a diameter of a first section of the metal container to form a first expanded section are performed in a single stroke of a single die. In some embodiments, the step of expanding a diameter of a first section of the metal container to form an expanded section is performed after the step of curling outward a top edge of the metal container to form a curl.

A metal cup and method of forming the same is provided. Metal cups of the present disclosure comprise a plurality of thin, straight-walled sections and a tapered profile. A domed portion is provided in the bottom of the cup. The cup may comprise a disposable cup, a reusable cup, or a recyclable cup.

A method and apparatus for forming aerosol cans for metered dose inhalers.

Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.
