A domer station having a domer assembly, a housing assembly, and a stacked piston assembly is provided. The domer assembly is movably disposed within a domer body passage located in the housing assembly and structured to move between a forward, first position and a retracted, second position. The stacked piston assembly includes a plurality of pistons, preferably three pistons, disposed in series and a pressure supply. The pistons are disposed behind the domer in pressure chambers. The pistons have a constant pressure applied thereto and are biased towards the domer. The pistons are, however, each restrained by a stop and do not contact, or operatively engage, the domer when the domer is in the domer first position.

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 of manufacturing an aerosol generation system heater element is described. The aerosol generation system heater element comprising a seamless hollow tube, and the method comprises deforming a wall of a hollow tube to form the seamless hollow tube, the seamless hollow tube having a deformed wall, wherein the deformed wall of the seamless hollow tube is thinner than the wall of the hollow tube.

Methods and apparatus of decorating metallic containers are provided. More specifically, the present invention provides novel apparatus and methods of forming an indicia or a decorative shape on a closed end-wall of a metallic container body. A tool of one embodiment of the present invention is operable to form an indicia in a metallic sheet. A cupping apparatus can subsequently form a cup from the metallic sheet which includes the indicia. The cup can be formed into a container body by a bodymaker. In another embodiment, a tool of a bodymaker is operable to form an indicia or a decorative shape in a closed end-wall during formation of a metallic container body. The indicia or decorative shape can be formed by coining, punching, embossing, debossing, and other techniques of forming and shaping metal material from which the metallic container body is formed. In this manner, the indicia may include one or more raised portions and sunken portions in the closed end-wall. Optionally, the indicia may enhance the strength of the closed end-wall, such as to prevent or resist buckling and deformation.

Provided is a press molding method in which a plate material is molded into a target molded body including a ridge section, said method including: a first step for molding an intermediate molded body; and a second step for forming the target molded body from the intermediate molded body. The target molded body and the intermediate molded body have coincident regions where the cross-sectional shapes coincide on both sides of an intermediate ridge section, and an intermediate region where the cross-sectional shapes do not coincide. The intermediate region includes: an outer region in which the intermediate molded body protrudes outward of an edge radius with respect to the target molded body; and an inner region in which the intermediate molded body is curved inward of the edge radius with respect to the target molded body.

A container, such as a beverage or food can is provided, which includes a first sidewall, a second sidewall and a bottom portion extending between the first and second sidewalls. The material of the bottom portion is stretched relative to the first sidewall and the second sidewall to form a thinned preselected profile, such as a dome. The material of the container at or about the dome has a substantially uniform thickness. The container is formed from a blank of material, which has a base gauge prior to being formed. After being formed, the blank of material of the container at or about the dome has a thickness less than the base gauge. Tooling having a clamp bead, or a progressive clamp bead, for selectively forming a blank of material into a container, as well as an associated method are also disclosed.
