Laser technology

the Laser technology is one of the four major scientific and technological inventions in the twentieth century that are famous for atomic energy,

semiconductors, and computers.Laser applications

Laser has good monochromaticity, coherence, and directivity, and can accumulate high energy density in a small area,

which is especially suitable for material processing.

thus In the late 1970s and early 1980s, a brand new laser application technology—laser marking technology—was quietly emerging internationally,

and quickly became industrialized, becoming one of the largest application fields of laser processing.

Laser marking technology uses computer-controlled laser as the processing method.

Its basic principle is: computer-controlled high-energy-density focused laser beam acts on mechanical parts,

electronic components, instruments and other workpiece surfaces that need to be marked according to a predetermined trajectory.Laser applications

The surface material can  instantly vaporized or chemically changed to change the color,

and characters and patterns with a certain depth or color are etched, thereby leaving permanent marks on the surface of the workpiece.

Laser marking technology,

as a modern precision machining method, has unparalleled advantages compared to traditional machining methods such as corrosion,

electric discharge machining, mechanical scoring, printing:
firstly  The laser could  the processing means, and there is no processing force between the workpiece and it has the advantages of no contact,

no cutting force, and small thermal influence, which ensures the original accuracy of the workpiece.

At the same time, it has a wide adaptability to materials, can make very fine marks on the surface of a variety of materials, and has very good durability;
secondly  The laser has good space controllability and time controllability. It has great freedom in the material, shape, size and processing environment of the processing object, and is especially suitable for automatic processing and special surface processing.

And the processing method is flexible, which can not only meet the needs of laboratory-style single design, but also meet the requirements of industrialized mass production;
3. Laser engraving is fine, lines can reach millimeters to micrometers.

Marking and modification using laser marking technology are very difficult, which is very important for product anti-counterfeiting;
4. The combination of laser processing system and computer numerical control technology can constitute efficient automatic processing equipment,

which can print a variety of words, symbols and patterns,

thus easy to design marking patterns with software, change the marking content, and meet the requirements of modern production with high efficiency and fast pace;

5. Laser processing has no pollution source and is a clean and pollution-free high environmental protection processing technology;
thus Laser marking technology could in all walks of life, opening up broad prospects for high-quality, efficient, pollution-free and low-cost modern processing and production.

With the continuous expansion of the field of modern laser marking applications,

the requirements for the miniaturization, high efficiency and integration of laser manufacturing equipment systems are also higher.
