A fluid-cooled toolpack for cooling can-forming dies without allowing cooling fluid to contaminate or contact the cans or the interior of the can bodymaker during production. The fluid-cooled toolpack generally includes a chill plate that is biased with a spring into contact with a can-forming die. The chill plate may be generally ring shaped and include annular heat pipes to carry heat away from the can-forming die to a set of heatsink fins at the top of the chill plate. Cooling fluid, such as water or air, can be used to remove heat from the heatsink fins. The chill plate can also be used to preheat the can-forming die before the equipment is used if desired, since the heat transfer of the system is non directional.
