• The disc is spun against the metal surface at moderate pressure.
• Friction creates localized heat on the high (stretched) areas of the panel.
• The hot spots are quickly cooled with a wet rag or spray bottle.
• The rapid cooling causes the metal to contract, shrinking the stretched areas.

Repeated cycles of heating and cooling allow for precise control over the metal’s shape.

Key Features & Benefits:

• Provides controlled metal shrinking without thinning or damaging the panel.
• Produces a smooth finish, since it only affects high spots.
• Safer and gentler than flame shrinking.
• Ideal for panel straightening, weld repair, and finishing.
