Characteristics of laser marking

Compared with traditional methods such as mechanical engraving, chemical etching, screen printing, and ink printing, laser marking has the advantages of low cost, high flexibility, and environmental friendliness; It can be controlled by computer systems, and the strong and permanent marking generated by the laser acting on the surface of the workpiece is its outstanding feature.

A. Non contact: Laser marking is processed using a non mechanical 'light knife', which can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, ensuring the original accuracy of the workpiece. No corrosion occurs on the working surface, no tool wear, no toxicity, and no pollution.

B. Permanent: The mark will not fade due to environmental factors such as touch, acidic and reducing gases, high temperature, low temperature, etc.

C. High carving accuracy: The laser marking machine carves fine patterns on objects, with a minimum line width of 0.04mm. Clear, durable, and aesthetically pleasing markings. Laser marking can meet the need to print large amounts of data on extremely small plastic parts. For example, printing two-dimensional barcodes with higher precision and clarity requirements has stronger market competitiveness compared to embossing or spray marking methods.

D. Low operating costs: The marking speed is fast and the marking is formed in one go, with low energy consumption, resulting in low operating costs. Although the equipment investment of laser marking machines is larger than traditional marking equipment, the operating cost of using laser marking machines is much lower.

E. High processing efficiency: Under computer control, the laser beam can move at high speed (up to 5-7 meters/second), and the marking process can be completed within seconds.

F. Anti counterfeiting: The markings carved using laser marking technology are not easy to imitate or change, and have strong anti-counterfeiting properties to a certain extent.

Installation environment requirements:

1. Preventing vibration: The optical path of the laser marking machine is very precise, so the working environment must be stable. If there is vibration in the working environment, it will cause changes in the optical path of the laser marking machine, and the laser effect will also be directly affected!
2. Reduce dust: Because there are many optical components and precision electronic components inside laser equipment, it is necessary to prevent dust from adhering to the laser and those optical lenses, which can affect the quality of light.
3. Voltage standard: The electrical voltage of the laser welding machine must strictly follow the national standard, and there should be no large fluctuations in voltage. If there is voltage fluctuation, it is recommended to install a voltage regulator, and the working environment should be kept away from high-power machinery and equipment.
4. Good grounding: Only correct and good grounding can ensure their normal operation. The laser power supply and welding control system both use industrial microprocessors for digital control, and only good grounding can ensure their normal and stable operation
