Laser hardening for flexible dies

Laser hardening is a process in which the tip of the cutting line is hardened by a laser, controlled by a specially developed computer controlled procedure. This gives maximum possible lifetime of the flexible die.


Laser hardening is generally recommendable for cutting-through as well as for difficult-to-cut filmic materials in large runs.

The benefits:

  • maximum possible lifetime (hardness at top of cutting line: 66-68 HRC)
  • trouble-free kiss-cutting and cutting-through, also with difficult materials
  • no impairing of the flexibility
  • no magnetic adhesion loss
  • no additional tolerance differences

1. The complete cutting line is tempered by laser in its upper part, and then cooled off.

2. The result: A harder steel structure at the tip of the cutting edge, with homogeneous transition to the residual die.
