What is industrial laser marking?+
Industrial laser marking uses a focused beam to change the surface of a material, producing a permanent mark by ablating a coating, foaming or carbonizing a plastic, or engraving a metal. Nothing is added to the product, so the resulting code cannot be smudged or wiped away.
What is the difference between CO2, fiber, and UV lasers?+
CO2 lasers are commonly used on coated papers, cartons, many plastics, glass, and rubber. Fiber lasers are generally selected for metals and dense plastics. UV lasers operate at a shorter wavelength with less heat, which suits fine detail, sensitive plastics, and flexible films.
Do laser systems require ink or ribbon?+
No. Laser marking is consumable-free in the sense that there is no ink, solvent, or ribbon to replenish. Applications often still require fume extraction, protective optics, safety enclosures or interlocks, and periodic lens cleaning depending on the material and environment.
What information does ATP need to evaluate a laser application?+
Helpful details include the exact material and any coating, the required mark and contrast, code size and content, production speed, whether the product moves or is stationary during marking, focal distance, available space, and the site's safety and extraction requirements.
