Analysis & Troubleshooting of Can Punch Failure Modes

In the production of high-quality two-piece aluminum beverage cans, the can punch is critical in the redrawing, ironing, and doming processes within the can bodymaker. The proper design of a can punch requires a high-quality carbide grade, precise geometry, and flawless surface finish.

For optimal performance, the bodymaker's working parameters, such as alignment, squareness, pressure, and coolant settings, are equally important. Neglecting these parameters can lead to punch failure modes and render even a perfectly designed can punch ineffective.

In this tech note, the can tooling experts at Hyperion Materials & Technologies analyze can punch failure modes commonly attributed to improper working conditions in the bodymaker and provide troubleshooting solutions to improve overall bodymaker performance and generate savings for can makers.
