Punching 12-Gauge Stainless Steel with Eight Rectangular Punches Would Require 43 Tons using the footowing formula:
Perimeter X Material Thickness X Shear Stringth (in Tons) = Required Tonnage
To Determine the Exact Press Tonnage Required is to Cycle the Tool in the Press with No Material and Measure the Tonnage.
