摘要： Embodiments provide a tooling station for forming containers that includes 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 includes a blank and draw punch curved edge disposed between a blank and draw punch inner circumferential wall and a blank and draw punch proximal surface. The blank and draw punch curved edge has a radius of curvature that varies along its circumference. The tooling station also includes a draw-redraw die configured to redraw the cup to form a can having a flange. The draw redraw die includes a draw-redraw die curved edge disposed between a draw-redraw die inner circumferential wall and a draw-redraw die proximal surface. The draw-redraw die curved edge has a radius of curvature that varies along its circumference.
