Product Description
Reaction UV lasers work a little differently to their CO2 or Fibre based siblings as they do not damage the materials surrounding surface, using a far lower power form of marking. This makes them the best of the bunch when it comes to “marking”, suitable for anything from fruit, to glass, teflon, diamond, silicone, plastic and precious metals. You really can mark almost anything with a UV laser!
How do UV laser marking systems work?
Operating at 355nm, UV lasers have a much shorter wavelength than the other technologies here. Using a process termed “cold processing”, UV lasers shoot high-energy photons in the ultraviolet spectrum that break the chemical bonds in the material which causes the material to undergo non-thermal process damage. This process does not produce thermal deformation (heat damage) on the inner layers and nearby areas of the target area.
In summary, the UV marking process is extremely fine and controlled, making it great for delicate or accurate work. However, due to the process this technology employs, a UV laser marking system is not normally suitable for engraving or cutting.
- Suitable for marking the widest range of materials
- Great for delicate, accurate work
- Very low power requirements
- Long-life and maintenance-free period
- Not very suitable for cutting or engraving
- More expensive than CO2
Frequently Asked Questions
What materials can the UV laser marking machine process?
UV lasers are highly versatile due to their short 355nm wavelength. They are suitable for marking a wide range of materials, including glass, wood, Teflon, silicon, paper, various plastics (like PE, PP, PVC), and precious metals.
What is "cold processing" and why is it beneficial?
Cold processing uses high-energy ultraviolet photons to directly break the chemical bonds within the target material, rather than relying on thermal energy (heat) to melt or burn it. This ensures no heat-affected zone remains, preventing thermal deformation or burning on adjacent layers.
Can this machine be used for deep metal engraving or cutting?
No, UV laser marking systems are designed for high-precision, superficial surface marking. Due to their lower heat output and specific processing mechanism, they are generally not suitable for deep engraving or cutting operations.
What is the difference between standard and 3D UV lasers?
Standard UV lasers are ideal for flat surfaces. The 3D UV laser marking system features dynamic focusing systems, making it capable of relief engraving and highly precise marking on irregular, sloped, or curved surfaces.
How is the cooling handled on 3W/5W models?
These industrial UV laser systems use water cooling systems to ensure the laser source maintains its optimal operating temperature, guaranteeing stability and extending the service life of components.
What maintenance does a UV laser marking machine require?
UV laser marking machines are designed to be virtually maintenance-free over long operational periods. Standard precautions include keeping the optical lenses clean and replacing the cooling water regularly.
