1. Permanent: The mark will not fade due to environmental factors (touch, acid and reduced gas, high temperature, low temperature, etc.).
2. Anti-counterfeiting: The engraved mark is not easy to be imitated and changed, and it has strong anti-counterfeiting to a certain extent.
3. Non-contact: Laser marking is processed by a non-mechanical "light knife", which can print marks on any regular or irregular surface, and the work piece will not produce internal stress after marking, ensuring the original accuracy of the work piece. No corrosion to the working surface, no "tool" wear, no poison, no pollution.
4. Wide applicability: It can process variety of metal and some of non-metal materials (aluminum, copper, iron, hard plastic and black cover material, etc.).
