Frequently asked questions
Which laser do I need — fiber, UV or CO2?
It depends on the material. Fiber (1064 nm) marks metals and many plastics, CO2 (10.6 μm) suits wood, paper and some plastics, and UV (355 nm) cold-marks heat-sensitive films and components.
Does it need ink or ribbon?
No — laser marking is permanent and consumable-free, so there is no ink, solvent or ribbon to replace.
How long does the laser source last?
The specification lists Laser service life:5000 working hours, which keeps long-term running costs low.
Can it mark heat-sensitive materials?
Yes — UV laser marking (355 nm) is a cold-marking process with minimal heat, making it suitable for heat-sensitive plastics, films and components.
What materials can this model mark?
It is suited to Wood, Carton, Bamboo, Leather, Plastic, Food, Paper, Fabric, Acrylic, Dark Glass. Send a sample and we will confirm the right wavelength and settings.
