High Precision UV Laser Engraving Machine, Cold Light Marker for Heat-Sensitive Materials

Overview

Our UV Laser Marking Machine is a high-precision industrial marking system equipped with a 355nm ultraviolet laser source. Unlike fiber and CO₂ lasers that rely on thermal ablation, it adopts cold processing technology. The laser energy directly breaks molecular bonds on the material surface instead of heating the workpiece, effectively avoiding burning, carbonization, discoloration or deformation. It delivers ultra-fine, high-contrast permanent marks without ink or consumables. It supports both static marking and online flying marking, and can be integrated with conveyor belts for automated mass production, which is widely favored for high-end precision marking applications.
