HNP Femtosecond Laser
Technology

Patented nano-scale surface processing that transforms cold forging die performance. Zero thermal damage. Measurable ROI.

Japanese Patent No. 7745860

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: dramatically reduced friction, extended tool life, and improved product quality — all achieved without coatings, chemicals, or thermal distortion.

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.
