Advanced Working Principle
The core technology lies in precisely controlling the laser-material interaction process:
1.For metallic materials, the system forms controlled oxide layers through precise laser parameter adjustments, producing durable, high-contrast markings that withstand extreme conditions.
2.For ultra-hard materials like sapphire, specialized laser wavelengths induce photochemical effects, creating nanostructures that diffract light for unique visual effects—both aesthetically pleasing and highly secure.
3.For coated materials, the system performs selective layer removal, precisely controlling marking depth to reveal underlying material colors—ideal for multi-layered security applications.
All processes are managed by an intelligent control system, ensuring industrial-grade consistency for every mark.
