Molds for forming formed containers with reduced or eliminated parting lines, and systems and methods of forming the formed containers, using electromagnetic radiation are disclosed. In some aspects, the forming mold includes a multi-segment mold disposed about an electromagnetic coil. The multi-segment mold having a plurality of circumferential segments, a bottom mold section and an annular ring. Each of the circumferential segments including an inner surface wherein the plurality of inner surfaces defines a desired shape of the formed containers. The bottom mold section being adapted to hold and move the pre-form articles about an electromagnetic coil and into and out of the forming mold. The annular ring being adapted to hold, seal and optionally shape a top section of the pre-form articles so as to reduce or eliminate parting lines on the surface of the formed containers.

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.

A spindle rotation unit includes: a plurality of attachment portions that are arranged in a base; a spindle that is rotatably attached to any one of the plurality of attachment portions; a motor plate that is attached to the base; a motor attachment flange that is attached to the motor plate; a driving motor that is attached to the motor attachment flange; and a transfer member that connects the driving motor and the spindle and transfers a rotational driving force of the driving motor to the spindle. The motor attachment flange is provided with an opening portion through which the transfer member is inserted and the motor attachment flange is disposed in the motor plate to allow its position to be adjustable so that the opening portion is opened toward a predetermined attachment portion to which the spindle is attached among the plurality of attachment portions.

A method of manufacturing a two-piece food can having improved corrosion resistance is provided, wherein the two-piece food can using a metal sheet coated with a thermoplastic resin and having annular uneven beads and/or a bottom rim. After forming a bottomed cylindrical can body by drawing and ironing, by heating at a temperature higher than the melting temperature of the thermoplastic resin for a predetermined time before forming uneven beads and/or a bottom rim to the can body and quenching within a predetermined time after heating, the inner resin coating hardly peel off during the following formation of uneven beads and/or the bottom rim. As a result, a two-piece food can having excellent corrosion resistance may be obtained.

The multi-segment mold having a plurality of segments, each segment including a mold insert having an inner surface. The plurality of inner surfaces defining a desired shape of the formed containers. Each mold insert being comprised of a material that comprises at least one of small pores, grooves, pockets and crevices. The material comprising the at least one of small pores, grooves, pockets and crevices being configured to allow air to pass through the multi-segment mold or to allow the air to be less compressed.

An apparatus and method for forming a deboss in a closed end-wall of a metallic cup is provided. The deboss apparatus generally includes a rotatable turret with tooling assemblies. The tooling assemblies are configured to receive a metallic cup formed by upstream equipment. The metallic cup formed by the upstream equipment has a closed end-wall that is generally planar. As the turret rotates, the tooling assemblies are configured to form a deboss in the closed end-wall of the metallic cup. In one embodiment, the deboss projects inwardly into an interior of the metallic cup. The metallic cup with a deboss is subsequently stripped from the tooling assembly for further processing.

A textured work roll can impart a desired texture on a metal substrate, such as an aluminum or aluminum alloy sheet. The textured work roll can be used for applying a gloss finish on the metal substrate. The textured work roll can be textured by grinding the work roll to form a ground work roll; electro-discharge texturing the work roll to form an electro-discharge textured work roll; and polishing the work roll to form a polished work roll. The polished work can have an Ra value between 0.30 m and 0.70 m. The polished work roll can be used to apply the gloss finish on the metal substrate.
