Glass wine bottle marking by nanosecond UV lasers source

Among the traditional marking methods of glass wine bottles, labeling and coding are the most common methods. For example, paper labels often cover product ingredients, origin, trademark, shelf life and other information, while glass bottles are marked with coding. production date, etc.

For consumers, through the marked information, consumers can easily buy the wine they want. For manufacturers, the significance of the mark is that they can use the information on the wine bottle to follow up on the quality of their products, manage warehousing and logistics, and control single-end sales.

The importance of marking cannot be overstated.

With the prevalence of wine culture and the improvement of consumers' anti-counterfeiting awareness of wine products, the requirements for information marking of wine bottles are getting higher and higher. The emergence of laser marking technology can meet the needs of high-quality marking of glass wine bottles.

The nanosecond UV lasers source marking is to focus the high-energy density laser beam on the surface of the beer glass bottle, make it vaporize in a very short time, and at the same time control the effective displacement of the laser beam, thereby leaving a smooth and textured mark pattern. Compared with the traditional marking process, the laser marking process has several advantages: first, the graphic information of the laser marking is clearer, permanent, tamper-proof and wear-resistant; second, the laser marking is non-contact. The processing method prevents the glass bottle from being damaged by external force and is friendly to the glass material; third, the line width of the laser marking can reach the order of microns, with high contrast, complex graphics and text can also be marked, and the anti-counterfeiting function is stronger; Laser marking has no consumables, no environmental pollution, and one-time forming, which reduces the risk of environmental pollution. Fifth, the laser marking process can be integrated into the production line, with a high degree of automation and very fast marking speed, reducing costs and improving efficiency for enterprises.

At present, with the improvement of the level of laser technology and the popularization of the automation of instruments and equipment, the application of laser marking in the bottle wine industry is very large, and the excellent performance advantages are gradually replacing the traditional processing methods. Due to the hard and brittle properties of glass, this factor needs to be fully considered in the selection of lasers.

The nanosecond UV lasers source is a cold light source, and marks "Bashi is very good" on glass wine bottles made of hard and brittle materials! Its pulse width is about 25ns, which can be described as an instant. The heat of the laser has stopped before it can accumulate in the glass bottle. With the high photon energy of ultraviolet light, the heat effect during marking is small and can be ignored, and the heat affected area is small. It avoids the occurrence of micro-heat marks due to heating during infrared nanosecond laser marking, which affects the visual sense. At the same time, it has the characteristics of high beam quality (M2<1.2) and small focusing spot, which can meet the ultra-fine marking requirements of glass products, and its small characters can reach micron level, in addition to being competent for high-resolution graphic marking , can also obtain anti-counterfeiting needs, and brand benefits can be guaranteed.

In addition, ceramic wine bottles commonly used in the liquor industry can also be marked with nanosecond UV lasers source to obtain high-quality marks.
