Technical Field

[0001] This utility model relates to the field of thermoforming mold technology, and specifically to an auxiliary heating device for large thermoforming molds. Background Technology

[0002] Metal hot forming dies are key tools used for plastic processing of metal materials at high temperatures. They are widely used in forging, extrusion, stamping, and other processes.
