HNP Femtosecond Laser
Technology
Patented nano-scale surface processing that transforms cold forging die performance. Zero thermal damage. Measurable ROI.
What is HNP?
HNP (High-performance Nano Processing) is our patented femtosecond laser surface treatment technology. By creating precisely controlled nano-scale textures on cold forging die surfaces, we fundamentally alter the tribological properties of the tool-workpiece interface.
The result is lower friction at the punch surface, which helps reduce galling and adhesion, along with longer tool life and more consistent product quality. HNP is normally applied after coating, on top of the existing coating. Processing before coating is under research. The treatment does not use chemicals and avoids thermal distortion.
Die Life Extension
In our internal evaluations, the typical improvement is about 1.5x, with up to 3x in some cases.

Why Femtosecond?
Understanding the physics behind ultra-short pulse laser processing.
Ultra-Short Pulses
Femtosecond = 10-15 seconds. Pulses so brief that material is ablated before heat can propagate, eliminating the heat-affected zone entirely.
Nanoscale Precision
Process features at the nanometer scale with absolute repeatability. Create surface textures impossible to achieve with conventional machining or coating methods.
Zero Thermal Damage
No heat-affected zone means no material deformation, no micro-cracking, and no change in metallurgical properties. The substrate retains its full mechanical integrity.
