Abstract: An ironing system includes a ram, a sensor system, and a punch nose. The ram includes a ram body and a ram nose, and the ram includes an inner surface that defines an inner chamber. The punch nose is connected to the ram nose via the sensor, and the sensor is configured to detect a force on the punch nose during an ironing process. An adaptor may be coupled to the inner surface of the ram, and the adaptor may support the sensor on the ram body.

Abstract: Provided herein are novel aluminum alloy compositions and methods of making and processing the same. The alloys described herein can be used in bottle making applications and exhibit enhanced runnability, formability, and appearance. The methods of producing an aluminum alloy sheet described herein can include casting an aluminum alloy to form an ingot, homogenizing the ingot, hot rolling the ingot to produce a hot band, and cold rolling the hot band to an aluminum alloy sheet of final gauge.

Abstract: The invention relates to a system for making a metal product, comprising - a lubrication source (225) for applying a first lubricant (235) on a punch side of a sheet metal blank (205); - a controllable current source (250) for applying different amounts of current; and - a punch (215) and a die (220) for drawing the sheet metal blank (205) into a metal product, wherein the controllable current source (250) is electrically coupled to one or more of the punch (215), the die (220), or a contact point for applying current through the first lubricant (235) while the sheet metal blank (205) is drawn by the punch (215) and the die (220) into the metal product and while the metal product is being ejected from the punch (215). The application further relates to a method for making a metal product with a such system. The invention relates also to a container manufacturing system (700), comprising - a cylindrical ram (720) comprising a ram body (722) and a ram nose on a distal end of the ram body (722), the ram nose engageable with a base of a container preform; - a die (730) comprising an opening concentrically aligned with the cylindrical ram (720), the opening sized and shaped for receiving the container preform in response to the ram nose engaging with the base of the container preform and the cylindrical ram (720) driving the container preform through the die opening; and - an ultrasonic device (740) coupled with the die (730), wherein the ultrasonic device causes the die (730) to vibrate while the cylindrical ram (720) drives the container preform through the die opening. The application further relates to a method for forming an aluminium container with such system and a die (730) for forming an aluminium container.

Abstract: This application discloses aluminum alloy products, such as can body stock and can end stock, that have improved processing qualities in high-speed production equipment due to engineered surfaces. For can body stock, processing is improved by providing at least two different surface roughnesses. For can end stock, processing is improved by reducing anisotropy at least at the top and bottom surfaces of the can end stock.
