355 nanosecond ultraviolet laser marking of food and drug packaging

The application and characteristics of ultraviolet laser marking machine are well known, the laser industry has become a "highland" for economic structure adjustment. Through technology grafting, laser has a broad market application in steel, chemical, automobile and other industrial production. The combination of non-standard automation and intelligence will drive the innovation and upgrading of the overall manufacturing industry and make the manufacturing process more efficient. The transformation and upgrading facing China's manufacturing industry is an opportunity for the transformation of traditional processing technology to laser processing technology. The application of laser marking is getting closer and closer to life, and the development of special UV marking machine marking in recent years can be said to be advancing by leaps and bounds.

Ultraviolet laser marking is to use ultraviolet laser to directly destroy the chemical bonds connecting the atomic components of the substance. This destruction is called a "cold" process, which does not generate heating of the periphery but directly separates the substance into atoms. The advantages of ultraviolet laser processing have led many companies to invest in the research and development of ultraviolet lasers. At first, only imported lasers were imported. Now, domestic ultraviolet lasers have gradually replaced the imported ones and penetrated into all walks of life in processing.

With the continuous progress of society, people's awareness of food and drug safety has also been continuously improved. In recent years, the state's supervision of food and drug safety has also been increasing. The paintable modification of the production date of the product has always been criticized by the general public. Many food and drugs are returned to the furnace after the expiration date and the production date is changed before they are put on the market. The practice of small workshops has also caused many large factories to suffer injustice. The application of nanosecond ultraviolet laser marking in the food and drug industry makes it impossible to alter the production date of food and drugs. It not only makes food and medicine safer, but also makes consumers more trustworthy in the manufacturer.

Laser nanosecond ultraviolet laser marking machine adopts high-quality nanosecond ultraviolet laser light source. Compared with ordinary laser marking machines, the diameter of the focused spot of the UV end pump laser is smaller, and the marking effect is finer; compared with the infrared end pump, the absorption rate of metal to UV light High, more suitable for precision marking on metal materials and glass materials. The laser with a narrow pulse width has a short interaction time with the processing material, and has a small thermal effect, and the marking effect is more beautiful.​​

Due to this feature, the nanosecond ultraviolet laser marking machine has the incomparable advantages of other laser equipment in the fine marking, fine cutting and engraving, and micro processing of special materials. Ultraviolet laser marking is permanent and indelible, as long as the surface of the object is not seriously damaged, the marking content cannot be destroyed. At the same time, the non-contact marking is used, so the object itself will not be damaged. Minsheng Laser has accumulated rich technical experience in the production line supply of laser marking machines. There are countless domestic and foreign customer cooperation cases, coupled with the company's innovative business philosophy of keeping pace with the times, focusing on production details, every The whole process of equipment from manufacturing to customer production line is controlled, and the quality inspection standards are strictly controlled, so that customers can choose and produce with confidence
