Tooling Profile Protection Through Coatings
The critical radius profile of the press brake die is often protected by specialized surface coatings (like Nitriding or Polishing). These treatments increase the surface hardness and reduce the coefficient of friction. This minimizes galling (material sticking) when bending stainless steel or aluminum, thereby preserving the die's forming geometry and extending the interval between tool regrinding cycles, maximizing the performance of your press brake tools.
