The laser printer uses a laser beam to permanently engrave characters or patterns on the surface of an object. It has high precision, high speed, and good anti-counterfeiting effect, and is suitable for the coding needs of various materials.
Laser marking generally includes 3 types, CO2 laser, fiber laser, and UV laser.

  CO2 Laser Fiber Laser UV Laser
Principle heating the surface of the product shorter wavelength, uses cold light to change the molecular structure of the surface, no heating damage
Suitable for paper, film, plastic, resin, rubber, leather, wood, acrylic, glass and PET, and other non-metal materials  Metal and plastic products metals or non-metals, thin plastic materials, inside of food bottle caps, circuit boards, anti-counterfeiting trademarks
Material composite film                           transparent materials composite film                             colored aluminum films composite film                                                                different material
Advantage mark organic materials and glass

Lower cost
Versatile range of applications
Long-life and maintenance-free
Fast engraving speeds
Suitable for marking the widest range of materials
Great for delicate, accurate work
Very low power requirements
Long-life and maintenance-free period
Disadvantage Shorter lifetime
Difficulties marking metals
