How DWI cans are made

Produced directly from the coil, DWI cans are stamped out by a cupper into the cup shape. The cup is drawn taller and narrower by the bodymaker as it’s pulled through ironing rings which stretch the metal to its final shape. DWI cans are thinner in the middle of the wall than at the bottom due to these ironing steps and are usually beaded for additional strength.
