Laser marking is a kind of laser processing, the use of high-energy density of the laser, the surface of the workpiece burning etched a permanent text or pattern.


Laser marking machine classification and selection:


According to different materials, different wavelengths of laser absorption of different characteristics, the general laser marking machine is divided into two categories, one is the use of YAG laser, suitable for processing metal materials and most of the non-metallic materials, such as iron, copper , Aluminum, gold, silver and other metals and various types of alloys, as well as ABS material, ink coating, epoxy resin and so on. Another type of CO2 laser, can only be processed non-metallic materials, such as wood, paper, acrylic, glass and so on. Some materials are also suitable for both types of laser marking machines, but there are differences in the effect of the process.


YAG marking machine, including lamp pump, semiconductor and fiber three categories, CO2 marking machine, including radio frequency tube and glass tube two categories, these five products constitute a laser marking machine standard models. For the actual needs of different users, with a different shape structure, fixture tooling, tailor-made software system, constitute a perfect laser identification solution.


Relative to the pneumatic marking, electric corrosion, silk screen, inkjet machine, mechanical engraving and other traditional marking methods, laser logo has the following advantages:


1. Laser processing for light contact, non-mechanical contact, no mechanical stress, it is particularly suitable for high hardness (such as cemented carbide), high brittleness (such as solar wafers), high melting point and high precision (such as precision bearings) High and other occasions to use.

2. Laser processing of the energy density is very large, short time, heat affected zone small, small thermal deformation, thermal stress is small, will not affect the internal electrical performance. Especially 532μm, 355μm, 266μm laser cold processing, suitable for special materials, precision machining.

3. Laser direct burning etching, for the permanent mark, can not be erased, will not fail deformation off, suitable for anti-counterfeiting anti-Cuanhuo, product traceability requirements.

4. Laser processing system itself is a set of computer systems, you can easily arrange, modify, there are jumping numbers, random code and other functions, to achieve the only product coding requirements, suitable for personalized processing, multi-batch processing of small quantities more Have an advantage.

5. Mark the effect of fine, beautiful technology, high precision, can enhance product quality, improve product added value.

6. Line width can be as small as 10μm, the depth of up to 10μm below, can be "mm" size of the surface parts of the mark.

7. Low supplies, non-polluting, energy saving and environmental protection, in line with European environmental standards, in line with the pharmaceutical industry GMP requirements.

8. Low processing cost. The one-time investment of the equipment is more expensive, but the continuous, large amount of processing eventually reduces the processing cost of each part.

9. Flexible processing methods. Through the transparent medium on the internal workpiece processing, easy to guide, focus, to achieve direction change, easily with the CNC system.
