Spinning dies turn a profit

"Machine sharpening creates a perfect angle every time. We can guarantee an angle. It's a phenomenon, a real breakthrough in the rotary die business."

Laser hardening is one of the newest die-improving technologies. In this process, a laser is used to harden the cutting line by heating the die to a specific temperature. Once the die reaches the predetermined temperature, the structure of the material is changed, resulting in a longer-life die, Hasselberg said. "For dies used to cut abrasive material, [laser hardening] increases the die life by 100 to 300 percent," he said.
