NEW GEKA USA Punching Capacities Calculator
Perimeter(p) x Thickness x Tensile/2000 = US Tons
Please refer to the below drawing for more information about how to calculate the perimeter (p) of the most common shapes.
CAUTION: Never punch a diameter
smaller than the material thickness
Please select a shape and introduce measures:
Fill in two of the three first fields and get the result for the missing
field.
Resistance is a compulsory field.
Example: for a given diameter, thickness and strength*, work out the tonnage.

DISCLAIMER
| Material Name | Minimum Tensile | Maximum Tensile |
|---|---|---|
| A36 | 58000 | 79800 |
| 1018 | 64000 | |
| 304 | 73200 | |
| 304 | 73200 | |
| 316 | 84100 | |
| 316L | 81200 | |
| 6061 T6 Aluminum | 45000 | |
| Copper | 35000 |
Nevertheless, it is very important to apply
the correct gap between punch and die:
the correct gap between punch and die:
| THICKNESS | RECOMMENDED DIE CLEARANCE |
|---|---|
| 1/8″ to 1/2″ | 1/32″ |
| 1/2″ to 3/4″ | 1/16″ |
| Mild steel (ST37 to 42) | 10 % |
| 3/4″ to 1″ | 3/32″ |
| 1″ & + | 1/8″ |
