Provisional Application No. The present application relates generally to a system and method for manufacturing metal containers, and in particular, to a system and method for controlling the Camesa Company projection of the metal containers during the manufacturing of the metal containers.

Container manufacturing e. Stock may include any metal material such as aluminum, steel, and metal alloys. For example, some conventional container manufacturing methods include a draw-redraw DR process to produce a can. In this method, a blank and draw punch is first used to create a metal cup by blanking off a portion of stock from a coil and drawing the metal between two pieces of tooling e. The cup forms across the tangent points of the inner radiuses of the blank and draw punch. The draw-redraw die is then used to redraw the cup across the tangent points of the inner radiuses of the draw-redraw die to form a can having a flange.

After the flange is formed, portions of the outer circumference of the flange may be trimmed off to produce an even substantially round flange edge.

In this method a blank and draw punch is used to create a metal cup by blanking off a portion of stock from a coil and drawing the metal between two pieces of tooling e.

The foregoing and other aspects of the present invention are best understood from the following detailed description when read in Ekl Machine Company with the accompanying drawings.

For the purpose of illustrating the invention, there is shown in the drawings embodiments that are presently preferred, it being understood, however, that the invention is not limited to the specific instrumentalities disclosed. Included in the drawings are the following Figures:.

As described above, a portion of metal is blanked from a coil of stock to be drawn and formed into a cup. In conventional systems and methods, when the cup is formed, the height of the cup wall varies around the circumference of the cup at the cup top.

That is, the metal is unevenly distributed at the cup top. The trimmed off portions are essentially wasted portions of materials e. For cans produced using the DRD process described above, when the cup is redrawn to form the can, a flange is formed that extends from the can sidewall. The width of the flange from the can sidewall to the edge of the flange varies around the circumference of the flange.

That is, the redrawing of the metal causes an earring effect by which portions of the flange are caused to be wider than other portions of the flange. Because it is desirable to have a minimum flange width and an evenly distributed e. The trimmed off portions are essentially wasted portions of metal that are not part of the produced can. The minimum amount of metal blanked off the coil may be determined by the overall size of the radius continuously around the inner circumference of the draw punch.

If the overall size of the inner radius of the draw punch is increased, the metal is less constricted to provide a shorter cup, thereby providing less metal on the flange and a smaller flange width. Reducing or increasing the overall size of the inner radius of the draw punch does not, however, prevent the uneven distribution of metal to the flange. That is, regardless of the overall size of the inner radius of the draw punch, the width of the flange from the can sidewall to the edge of the flange varies around the circumference of the flange.

The cost to produce each can includes the cost for the amount of metal used to form each can. Accordingly, if the portion of metal used to form the can is decreased, then the cost to produce each can decreases. The varied inner radiuses of the blank and draw punch reduce the amount of metal to be trimmed off the cup top, thereby decreasing the cost of producing the cup. The varied inner radiuses of the draw-redraw Holman Boiler Works Company decrease the amount of metal used to form a can while maintaining a desirable minimum flange width around the outer circumference of the flange, thereby decreasing the cost to produce the can.

Embodiments provide a method and system that includes both a blank and draw punch having varied inner radiuses and a draw-redraw die having varied inner radiuses. In some embodiments, the cup and the can may be formed at a single tooling station having both the blank and draw punch and the draw-redraw die.
