DON'T DISASSEMBLE IT
Traditional methods of freeing presses included disassembling the press, cutting the parallels, or heating the tie rods - all of which may cause damage to the press. Press freeing with liquid nitrogen is faster and more safe.
Liquid nitrogen is applied to the pressure points of the seized press. These cooled pressure points contract and relieve the pressure thereby freeing the press with no metallurgic change.
Once the press is released and back to room temperature, the press will function normally and no further adjustments will be needed.
