Laser marking machines can be divided into fiber laser marking machines, CO2 laser marking machines, and ultraviolet laser marking machines according to different lasers.Different work piece materials have different choices of laser marking machines, and different wavelengths and powers are suitable for marking materials.
The laser wavelength of the fiber laser marking machine is 1064nm, which is suitable for most metal materials and some non-metal materials, such as cloth, leather, glass, paper, polymer materials, electronics, hardware, jewelry, tobacco, etc. The power of the fiber laser marking machine is: 20W, 30W, 50W, 70W, 100W, 120W, etc.
The laser wavelength of CO2 laser marking machine is 10.6μm, which is suitable for most non-metallic materials, such as paper, leather, wood, plastic, plexiglass, cloth, acrylic, wood and bamboo, rubber, crystal, jade, ceramics, glass and artificial Stone etc. The power of CO2 laser marking machine are: 10W, 30W, 50W, 60W, 100, 150W, 275W, etc.
The laser wavelength of the UV laser marking machine is 355nm. It is mainly used for ultra-fine marking and engraving. It is especially suitable for marking food, pharmaceutical packaging materials, drilling micro-holes, high-speed division of glass materials and complex silicon wafers. Graphic cutting, etc., usually white or black on transparent plastic. The power of UV laser marking machine are: 3W, 5W, 10W, 15W, etc.
1. The use effect of aluminum oxide black laser marking machine has always been a hot topic in the marking industry. Many people say that the laser marking machine is fast and efficient, and the pattern is clear and beautiful. So it is very popular. Like Apple mobile phone shells, markings on keyboards, lighting industry and so on. This is a MOPA fiber laser marking machine (also known as full pulse width laser marking machine) that requires adjustable pulse width. Ordinary laser marking machines can only print gray or black-gray text information on aluminum products. The difference is that this fiber laser marking machine can directly mark magnesium aluminum, aluminum oxide, and various aluminum materials with a black effect, while the general fiber laser marking machine cannot do this; anode The mechanism of aluminum oxide blackening is to further oxidize the anodic aluminum oxide layer with a film thickness of 5-20um and change the surface material in a very short period of time by focusing a laser with high energy density. The principle of aluminum blackening is based on the nano-effect. , Since the size of the oxide particles is nano-scale after laser treatment, the light absorption performance of the material is increased, so that visible light is irradiated to the material and absorbed, and the reflected visible light is very small, so it is black when observed by the naked eye. At present, the mobile phone LOOG and adaptation information on the market are all using the MOPA laser marking process.
2. The basic principle of color marking on stainless steel is to use a high-energy-density laser heat source to act on the stainless steel material to generate colored oxides on the surface, or to generate a colorless and transparent oxide film. The effect of light interference shows the color effect. Moreover, by controlling the laser energy and parameters, different colors of oxide layers with different thicknesses can be realized, and even color gradient marking can be realized. The application of laser color marking is a good complement to the appearance of stainless steel products. In addition, stainless steel itself has the advantages of good corrosion resistance and excellent decoration. Stainless steel products with color patterns are more widely used.
3. On-line flying marking On-line flying laser marking is the most specialized laser application technology. It combines the fiber laser marking machine with the assembly line to mark while feeding, which can greatly improve our work efficiency. Mainly used for a variety of molded and extruded products that need to be marked on outer packaging lines, such as wire/cable, tubulars and pipes. Compared with the static laser marking machine, the online flying laser marking machine, as the name implies, is a machine that performs laser coding on the surface of the product while the product is in motion next to the production line. Cooperating with industrial automation, where the workpiece is marked within a certain period of time is a manifestation of automation. The flying laser marking machine can automatically generate batch numbers and serial numbers. No matter how fast the product flows, the output of the marking light source is stable, and the marking quality will not change, so the work efficiency is high, especially the power saving, which is also the practicality of the flying laser marking machine. place.
4. Portable fiber laser marking machine Portable fiber laser marking machine, as the name suggests, is easy to carry, compact, does not occupy space, has good flexibility, environmental protection and energy saving, can be hand-held for operation, and can be used for laser marking of large mechanical parts in any direction. , For customers with low marking requirements, the portable laser marking machine is very suitable and can meet the basic marking needs.
