Laser has many advantages over traditional mechanical metal engraving in metal engraving:
1. Laser engraving does not need to be in contact with the engraved workpiece, so many fixtures and cutters are omitted, and the workpiece does not generate internal stress after marking, ensuring the original accuracy of the workpiece.
2. No corrosion on the working surface, no "knife" wear, no toxicity, no pollution.
3. The high-precision characteristics of laser engraving are also particularly suitable for the processing of complex graphics.
4. The mark will not disappear due to environmental relations (touch, acidic and subtractive gas, high temperature, low temperature, etc.), and it has high security.
5. Non-contact: Laser marking is processed with a non-mechanical "light knife", and marks can be printed on any regular or irregular surface.
6. Low operating cost: the marking speed is fast and the marking is formed at a time, the energy consumption is small, so the operating cost is low.
Although the equipment investment of the laser marking machine is larger than that of the traditional marking equipment, in terms of operating cost, the use of the laser marking machine is much lower.
