Heated metal forming tool |
摘要 |
A heated metal forming tool including an un-heated mounting plate that is attached to a press. A tool detail is attached to the mounting plate. Insulation surrounds the tool detail to thermally isolate it from the mounting plate, and from the tool surroundings. The tool detail is heated internally by heaters disposed in zones within the tool detail. The temperature of various portions of the tool detail can be independently controlled by varying the temperature within any of the zones.
