For the moment, the portable fiber laser marking machine is the most mature, longest-life, most widely used, and most affordable model on the market. It is widely used in the packaging industry, such as: anti-counterfeiting laser coding (medicine monitoring code) in the pharmaceutical industry. , alcohol anti-counterfeiting anti-track traceability system (caps) food and beverage anti-counterfeiting mark, daily hygiene supplies three-code mark, smart card information mark, tobacco anti-counterfeit mark, pipe online mark.

Using laser radiation to directly decontaminate, after the laser is absorbed by objects or dirt particles, it generates vibration, which separates the substrate and the pollutants. In the laser dry cleaning, there are two main ways to remove dirt particles: One is the instantaneous thermal expansion of the substrate surface, which generates vibrations to remove the particles adsorbed on the surface. The other is the thermal expansion of the particles themselves, causing the particles to leave the surface of the substrate.

In recent years, the level of laser drilling machine at home and abroad is at a stage of rapid development. The output power of the laser is gradually increasing, the pulse width is narrower and narrower, the frequency range is wider and wider, and other parameters are becoming more and more favorable. The direction of punching is developing.
