Hardware
Having addressed staging and lay- out, storage, retrieval and transport, and standardization of dies, select quick die-change hardware. This includes control boxes, hydraulic power units, die lifters, bolster extensions, transport (forklifts, mobile die carts and rail- mounted die carts), die tables and rolling bolsters, and die-storage racks and hydraulic clamps, with ledge and rod clamps being the most common.
