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.

  • Good beam quality , small focused spot, can realize ultra-fine marking, and fast marking speed and high efficiency;
  • Most materials can absorb ultraviolet laser, wider application range
  • Extremely small heat-affected area, no thermal damage, no material scorching problem;
  • High-performance ultraviolet laser, high-precision scanning galvanometer, high precision and long life;
  • Stable performance, small size and low power consumption

Wider application

3W UV laser marking machine is mainly used in the high-end ultra-fine processing,with fine and noticeable permanent mark, marking of pharmaceuticals, cosmetics and packaging materials, flexible PCB board marking and engraving, silicon Micro-hole engraving,LCD glass two-dimensional code marking, surface drilling of glassware, metal coating surface marking, plastic buttons, electronic components, gifts, communication equipment, ABS materials, etc.

Q:Why is the 3W UV marking machine cooled with water?

3W UV laser will produce a certain amount of heat during the operation, if it is not cooled in time, the UV laser cavity will be heated and thermally deformed, which will affect the quality of light and the marking accuracy and stability. Therefore, UV marking machine should be equipped with a chiller to cool it during operation.

Q:What are other power of UV laser marking machine optional?

This is a 3W UV laser, we can also provide 5W, 10W UV laser.
