    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 abase 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: The invention relates to the use of an acidic aqueous composition for pretreating cans, wherein an inorganic-organic conversion layer is formed in the course of the pretreatment, said conversion layer, as such, offering an excellent adhesive base for wax which improves sliding of the formed can and for the subsequent coating. The invention relates to a wet-chemical pretreatment method in which a can cylinder is first contacted with an acidic aqueous composition that contains water-soluble inorganic compounds of Zr, Ti, Si, Hf or Ce, and water-soluble polymers comprising carboxyl groups or hydroxyl groups; and subsequently is contacted with an aqueous wax dispersion. The invention further relates to an acidic aqueous composition suitable for the pretreatment method comprising water-soluble polymers selected from condensation products of glycoluril and aldehydes. The invention further relates to a method for producing can cylinders, said method including the pretreatment according to the invention.

    Abstract: Quality collars with long collar lengths, homogeneous wall thickness distributions, and high loadability even in high-strength materials such as steel can be achieved on workpieces according to the disclosed methods and devices. One example method involves drawing the workpiece such that the drawn workpiece has a flange region and a drawn region adjoining the flange region, wherein the drawn region has a wall region and a drawn base adjoining the wall region, with the wall region forming a part of the collar; punching the drawn base located in the drawn region of the workpiece such that a drawn-base subregion adjoins the wall region; expanding the drawn-base subregion such that the expanded drawn-base subregion forms a part of the collar; and at least partially ironing and/or expanding the collar.

    Abstract: The invention relates to use of an aqueous composition for pretreating can body stock, whereby an inorganic-organic conversion layer is formed, which effects outstanding sliding behavior of the shaped can body stock and in addition offers an outstanding holding primer for subsequent coating. The invention comprises a process in which can body stock which is deep-drawn to form a half-open can cylinder, before further shaping processes, is contacted with an acidic aqueous composition which contains water-soluble inorganic compounds of Zr, Ti, Si, Hf or Ce, water-soluble polymers having carboxyl groups or hydroxyl groups and also a dispersed wax. Both outer and inner surfaces of metallic can cylinders can be pretreated in the process. The invention also relates to an acidic aqueous composition for use in the pretreatment process, which contains water-soluble polymers selected from condensation products of glycoluril and aldehydes.
