Laser marking machine uses laser beam to print permanent marks on the surface of various substances. The main effects of laser marking machine are:

• 2.1.1. The surface layer of the target material is evaporated by laser light energy to expose the deep layer of the material;
• 2.1.2. Through the chemical and physical changes of surface materials caused by laser light, the required patterns and words are "engraved";
• 2.1.3. Part of the material can be burned by laser light, so as to show the patterns and characters to be etched.

The optical fiber laser marking machine is mainly composed of optical fiber laser, galvanometer, software control board, cabinet, horizontal table for placing workpieces, etc.

Laser marking machine is mainly used in the following industries: electronic components, integrated circuit (IC), electrical appliances, mobile phone communication, hardware products, tool accessories, precision instruments, glasses, clocks, jewelry, auto parts, plastic keys, building materials, PVC pipes, medical instruments, etc.

Applicable materials include: ordinary metals and alloys (all metals such as iron, copper, aluminum, magnesium and zinc), rare metals and alloys (gold, silver and titanium), metal oxides (all kinds of metal oxides), special surface treatment (phosphating, aluminum anodizing and electroplating surface), ABS materials (electrical appliance shell and daily necessities), ink (transparent keys and printed products), Epoxy resin (packaging and insulating layer of electronic components).

After the laser beam with the output wavelength of 1060 ± 10nm is internally expanded, it is emitted onto the mirrors of the x-axis and y-axis galvanometer scanners. The galvanometer scanners swing rapidly under the control of the computer to scan the laser beam in the two-dimensional directions of plane X and y. Through the lens, the laser beam is focused on the surface of the processed object to form a fine and high-energy density spot. Each high-energy laser spot is ablated and carved on the surface of the object in an instant. Through the continuous process controlled by computer, the pre arranged characters, graphics and other marking contents are permanently etched on the object surface.

• 2.4.1. Long Service Life & High Quality: The fiber laser marking machine adopts fiber laser, with a service life of 100000 hours and superior performance, ranking top in the world. High beam quality, basic mode (TEM00) output, focusing spot diameter less than 20um. The divergence angle is 1 / 4 of that of semiconductor pumped laser. Single line is thinner, especially suitable for fine and precision marking.
• 2.4.2. Compact & Low Power Consumption: Small size, low power consumption, and the power consumption of the whole machine is less than 500W; The built-in air-cooled cooling mode abandons the bulky water-cooling unit, covers a smaller area and is easier to install, which truly achieves energy saving and portability.
• 2.4.3. High Efficiency: High electro-optic conversion efficiency, simple and easy to use, no optical adjustment or maintenance, compact structure, high system integration and few faults.
• 2.4.4. Maintenance-free: Without any maintenance, it has long service life and is suitable for working in harsh environment.
• 2.4.5. Fast Processing Speed: The processing speed is fast, 2-3 times that of the traditional marking machine. The optical scanning galvanometer has high laser repetition frequency, high speed and no distortion.
• 2.4.6. Shielded Reflection: Fiber lasers are equipped with optical isolators to effectively shield the reflected light. They can operate on high reflective materials with bright surfaces such as gold, silver, copper, aluminum and silicon. They do not need to deviate from the center of the field mirror, which greatly expands the application field.
• 2.4.7. Powerful Marking Software: The marking software is powerful and compatible with CorelDRAW, AutoCAD and other software files; Support PLT, PCX, DXF, BMP, etc., and can directly use SHX and TTF font libraries; It supports automatic coding, printing serial number, batch number, date, bar code, QR code, automatic number skipping, etc., and USB interface output control.
