DEVICE AND METHOD CONFIGURED TO MANIPULATE FRICTION BETWEEN A WORKING PIECE AND A DEEP DRAWING TOOL IN A DEEP DRAWING PROCESS

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.
