Tonnage required using Urethane Dies is 4-6 x more than standard steel dies. Please ensure that you are within the tonnage limits of both the tooling and machine when bending large radii or long lengths
3. Other considerations • No marking • Excellent radius shape • One die for many radius applications
• High tonnage required • Die pad is a consumable item • Short flanges can be difficult
