    Working Principle

    UV laser marking machine is based on laser energy to break the bond between atoms or molecules so that they become small molecules vaporized, evaporated, this process is also known as "photo-etching" effect or "cold processing". Specifically, a very high load energy (ultraviolet) photons can break the chemical bonds within the material or the surrounding medium, to the material to non-thermal processes in the destruction of the inner layer and the surrounding area does not produce heating or thermal deformation, etc.. Due to the focusing spot is very small, and processing heat-affected zone is minimal, it can be ultra-fine marking and special materials marking.

    Main Features

    1. High precision

    The focused spot of UV laser is very small, so it can realize high precision marking and engraving.

    2. Low thermal effect

    Compared with infrared laser, UV laser has a small heat-affected zone, which does not cause thermal effect and material combustion, and the thermal effect on the processed material is negligible.

    3. Wide applicability

    It can be applied to a wide range of materials, such as plastic, glass, rubber, ceramics, paper, etc. It is especially suitable for ultra-fine marking and engraving.

    4. Environmentally friendly and non-polluting

    It does not require the use of ink and other consumables during operation, so it will not cause any environmental pollution problems.

    5. Easy to operate

    It is flexible in installation, easy to operate, and its modular design is easy to install and maintain.

    Frequently Asked Questions (FAQ)

    What is the working principle of the UV laser marking machine?
    It uses high-energy ultraviolet photons to break chemical bonds within the material or surrounding medium (a process known as "photo-etching" or "cold processing"). This non-thermal process destroys the inner layer without producing heat or thermal deformation in the surrounding area.
    Why is the thermal effect of a UV laser negligible?
    Unlike infrared lasers, the UV laser has a minimal heat-affected zone. It performs non-thermal destruction of chemical bonds, which prevents thermal effect and material combustion.
    What materials can be marked using this machine?
    This machine is highly adaptable and can mark a wide range of materials including plastics (like PVC and ABS), glass, rubber, ceramics, paper, LCD liquid crystal glass, metal surface plating, and more.
    Is the UV laser marking process environmentally friendly?
    Yes. The process does not require the use of ink or other consumables during operation, making it environmentally friendly and free of pollution issues.
    What cooling method does the machine use and what is its lifespan?
    The machine utilizes a water cooling method (industrial cold water mechanism) to ensure stable operation. The laser module has an expected service life of 20,000 hours.
    What are the precision capabilities of this machine?
    Due to a focusing spot diameter of less than 0.01mm, it achieves a minimum line width of ≤0.005mm and a minimum character size of 0.15mm, allowing for ultra-fine marking and engraving.
