Products from all walks of life will use laser marking machines or laser cij printers as long as they are used for anti-counterfeiting and traceability, so today's laser editor will introduce the use of laser marking machines on products What are the benefits of marking?

1. The marking is permanent: if the marking will not fade due to environmental relations (touch, acid and reducing gases, high temperature, low temperature, etc.). 2. Mark anti-counterfeiting: The mark engraved by laser marking technology is not easy to imitate and change, and has strong anti-counterfeiting to a certain extent. 3. Non-contact: Laser marking is processed with a non-mechanical 'light knifeNo corrosion to the working surface, no 'tool' wear, no poison, no pollution. 4. Wide applicability: using laser as processing method, it can process a variety of metal and non-metal materials (aluminum, copper, iron, wood products, etc.). 5. High engraving precision: The objects engraved by the laser marking machine have fine patterns, and the Z line width can reach 0.04mm. The markings are clear, durable and beautiful. Laser marking can meet the needs of printing large amounts of data on extremely small plastic parts. For example, two-dimensional barcodes that require more precision and higher definition can be printed, and compared with embossing or jet marking, they have stronger market competitiveness. 6. Low operating cost: The marking speed is fast and the marking is formed at one time, and the energy consumption is small, so the operating cost is low. 7. High processing efficiency: the marking process can be completed within seconds. 8. Fast development speed: Due to the combination of laser technology and computer technology, users can realize laser printing output only by programming on the computer, and can change the printing design at any time, which fundamentally replaces the traditional mold making process.

Today we will take a look at the most common 7 types of lasers Marking machine: 1. Fiber laser marking machine. The fiber laser marking machine uses a fiber laser. The fiber laser has the characteristics of small size (no water cooling device, air cooling), good beam quality (fundamental mode), maintenance-free, etc. . Mainly used in: marking the required characters, patterns, barcodes and other graphics on plastic, electronics, metal, ceramics, tobacco and other materials. 2. Ultraviolet laser marking machine, the ultraviolet laser marking machine is developed with a 355nm ultraviolet laser. The 355 UV light has a very small focusing spot, which can greatly reduce the mechanical deformation of the material and has a small thermal effect of processing. It is mainly used in products that enterprises have higher requirements for text and patterns. 3. The semiconductor laser marking machine is mainly used in the same industry as the fiber laser marking machine, but with the increasingly fierce market competition, the progress of optical fiber technology is getting faster and faster. Now the semiconductor laser marking machine on the market has been slowly replaced by the fiber laser marking machine. 4. CO2 laser marking machine, CO2 laser marking machine is mainly used in some occasions requiring finer and higher precision, such as food, medicine, leather, tobacco, wood products, electronics and other non-metal industries. The effect of marking is more fine and beautiful than the effect of silk screen and inkjet. 5. End-pumped laser marking machine, end-face laser marking machine uses a solid-state laser pumped by a semiconductor laser as a pumping source, and is coupled with a fiber to inject a laser crystal from the end face. The pump beam entering the gain medium and the cavity mode space Z overlap to a large extent, so that the laser output with high power and high beam quality can be obtained. The main application industry is also the same as the fiber laser marking machine, and the performance is similar to that of the fiber laser marking machine, but its peak power is higher. 6. Green laser marking machine is mainly used for surface and internal marking of glass, crystal products, ceramics, metals, electronics, plastics and other products. It belongs to the category of cold light, and is also suitable for some products that have a relatively large response to heat and require high precision. 7. The flying laser marking machine is a dynamic marking function developed on the basis of the above laser marking machines. It is mainly used in assembly line operations. It can mark products without limitation for 360 days, and can also automatically generate assembly lines. The number and batch number thus greatly improve the production efficiency of the enterprise.
