Match your die closed height to the press shut height and adjust packing so the die runs at the correct setting.
Shut height is the bed-to-ram distance at the bottom of the stroke. The die’s closed (shut) height must match it so the die fully forms the part without overloading the press.
Set the press shut-height adjustment, then fine-tune with parallels/packing so the die closes exactly at bottom dead center.
Formula: Die closed height = Press shut height (at bottom of stroke)
