A tooling station for forming containers, comprising: (i) a blank and draw punch configured to blank off a portion of stock from a stock element and draw the portion of stock to form a cup, the blank and draw punch comprising: a blank and draw punch inner circumferential wall defining a blank and draw punch cavity; a blank and draw punch proximal surface extending substantially perpendicular to the blank and draw punch inner circumferential wall; and a blank and draw punch edge having a curved profile disposed between the blank and draw punch inner circumferential wall and the blank and draw punch proximal surface; and (ii) a draw-redraw die configured to redraw the cup to form a can having a flange, the draw-redraw die comprising: a draw-redraw die inner circumferential wall defining a draw-redraw die cavity; a draw-redraw die proximal surface extending substantially perpendicular to the draw-redraw die inner circumferential wall; and a draw-redraw die edge having a curved profile disposed between the draw-redraw die inner circumferential wall and the draw-redraw die proximal surface, characterised in that the curved profile of the blank and draw punch edge has a radius of curvature that varies with different circumferential positions along that edge, and in that the curved profile of the draw-redraw die edge has a radius of curvature that varies with different circumferential positions along that edge. (i) a blank and draw punch configured to blank off a portion of stock from a stock element and draw the portion of stock to form a cup, the blank and draw punch comprising: a blank and draw punch inner circumferential wall defining a blank and draw punch cavity; a blank and draw punch proximal surface extending substantially perpendicular to the blank and draw punch inner circumferential wall; and a blank and draw punch edge having a curved profile disposed between the blank and draw punch inner circumferential wall and the blank and draw punch proximal surface; and a blank and draw punch inner circumferential wall defining a blank and draw punch cavity; a blank and draw punch proximal surface extending substantially perpendicular to the blank and draw punch inner circumferential wall; and a blank and draw punch edge having a curved profile disposed between the blank and draw punch inner circumferential wall and the blank and draw punch proximal surface; and (ii) a draw-redraw die configured to redraw the cup to form a can having a flange, the draw-redraw die comprising: a draw-redraw die inner circumferential wall defining a draw-redraw die cavity; a draw-redraw die proximal surface extending substantially perpendicular to the draw-redraw die inner circumferential wall; and a draw-redraw die edge having a curved profile disposed between the draw-redraw die inner circumferential wall and the draw-redraw die proximal surface, characterised in that the curved profile of the blank and draw punch edge has a radius of curvature that varies with different circumferential positions along that edge, and in that the curved profile of the draw-redraw die edge has a radius of curvature that varies with different circumferential positions along that edge. a draw-redraw die inner circumferential wall defining a draw-redraw die cavity; a draw-redraw die proximal surface extending substantially perpendicular to the draw-redraw die inner circumferential wall; and a draw-redraw die edge having a curved profile disposed between the draw-redraw die inner circumferential wall and the draw-redraw die proximal surface, characterised in that the curved profile of the blank and draw punch edge has a radius of curvature that varies with different circumferential positions along that edge, and in that the curved profile of the draw-redraw die edge has a radius of curvature that varies with different circumferential positions along that edge.
