Patent abstract
A hot forming tool is heated with multiple electrical resistance cartridge heaters. The heaters are located in the body of the tool so as to maintain the entire forming surface within a predetermined temperature range. Numerical thermal and optimization analyses direct the placement of the heaters so that when each heating element is simultaneously powered on for an identical fraction of the time, an acceptable temperature distribution will be produced within the tool at the tool operating temperature.
