UV Laser Marking Machine
UV laser marking machine adopts high-performance ultraviolet laser and digital high-speed scanning galvanometer to make up for the shortcomings of infrared laser processing.With small heat-affected area, good beam quality and small focus spot advantages,which can engrave ultra-fine marks,suitable for marking of most metal and non-metal materials, especially special materials like chips and other fine marking.
Compared to the infrared laser,3W UV laser marking machine adopts 355nm UV laser source,ultraviolet laser marking utilizes laser energy to break the bonds between atoms or molecules of material,making them become small molecules and vaporize.
Due to its light spot is extremely small and belong to “cold marking”,ensure to greatly reduce the mechanical deformation of the material and thermal damage.It can be used for ultra-fine marking and special material marking. 3W laser marking machine is the first choice for customers who have higher requirements for marking effect.
