From the working principle and marking effect of the laser marking machine, the advanced laser marking machine has many advantages over the traditional marking methods (pad printing, code spraying, electric corrosion, etc.) due to its special working principle:
1. Non contact processing can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, which greatly improves the application range of marking;
2. The laser marking machine has a wide range of applications to materials, which can mark different types or hardness materials such as metal, plastic, ceramics, glass, paper, leather, and can ensure excellent marking effect;
3. The laser marking machine has strong applicability and high flexibility, and can be integrated with other equipment on the production line to improve the automation of the production line;
4. The identification effect is clear, lasting and beautiful, and can be effectively anti-counterfeited; The marking machine replaces the traditional inkjet printer, without consumables, long service life and pollution;
5. Low operation cost, fast marking speed and one-time marking, low energy consumption and low operation cost.
6. The processing efficiency is greatly improved. The laser beam under the control of the computer can move at a high speed (up to 5-7m / s), and the marking process can be completed in seconds. The printing of a standard computer keyboard can be completed in 12 seconds. The laser marking system is equipped with a computer control system, which can flexibly cooperate with the high-speed assembly line.
7. The development speed of laser marking machine is fast. Due to the combination of laser technology and computer technology, users can realize laser printing output as long as they program on the computer, and can change the printing design at any time. It fundamentally replaces the traditional mold manufacturing process, and provides a convenient tool for shortening the product upgrading cycle and flexible production.
8. High processing accuracy. The laser can act on the material surface with an extremely fine beam, and the thinnest line width can reach the micrometer level, creating a broad application space for precision processing and increasing anti-counterfeiting functions. Laser marking can meet the need of printing a large amount of data on very small plastic parts. For example, two-dimensional codes requiring more accuracy and clarity can be printed, which has stronger market competitiveness compared with imprinting or jet marking.
9. Low maintenance cost. Laser marking is non-contact marking, unlike the template marking process, which has a service life limit, the maintenance cost in batch processing is extremely low.
10. It is environmentally friendly. Laser marking is non-contact marking, which saves energy and avoids chemical pollution compared with corrosion method; Compared with mechanical marking, noise pollution can also be reduced.
