As shown in the above image, the bottoming involves the following three steps. Step-1: Place the sheet metal workpiece against V-Die. Step-2: Sheet metal punch bends the workpiece up to the punch angle to compensate for the impact of spring-back. The punch angle is always less than the die angle.
In the industrial series production of electrodes, a continuous slot die process is used, which is usually followed by a convection drying step. The wet film thickness ranges from 150 to 300 ?m and results in a dry film thickness of more than 100 ?m. Compared to coating, drying represents the speed-determining production process.
