How to choose a good laser marking machine
Laser marking machine according to different lasers can be divided into: CO2 laser marking machine, UV laser marking machine, fiber laser marking machine. These three laser marking machines are suitable for different materials
CO2 laser marking machine is suitable for all kinds of non-metallic materials, such as bamboo products, wood products, paper, cloth, plexiglass, epoxy resin, shells, etc., can be widely used in various industries, such as craft gifts, furniture, leather clothing, advertising signs, model making, food packaging printing plate production, shell nameplate.
fiber laser marking machine is applicable to various metal materials, such as iron, copper, manganese, aluminum, magnesium alloy, copper alloy, aluminum alloy and other ferrous and nonferrous metal materials.
The UV laser marking machine can mark metal, plastic, glass and other non-metallic materials, and is used in semiconductor, electronic and electrical housing, auto parts marking, glass processing, medical equipment and engineering plastic marking and other fields. The UV laser marking machine can be widely used in various materials.
In addition to different types of lasers with different materials, what else should we pay attention to when purchasing laser marking machines
1: The first is the wavelength. Under normal circumstances, the wavelength can be matched with the machine. Generally, the non-metallic machine is 10.6 microns, that is, the CO2 laser marking machine. The optical fiber marking machine is 1064nm, which is the main metal marking machine. The wavelength of the UV laser marking machine is 355nm.
2: The second is format. Many customers think that they must buy a machine with large field mirror format for long-term benefits. They think that the larger the format, the better. In fact, the larger the field mirror is, the greater the working distance between the field mirror and the focal length is. The attenuation of laser energy in the air is very severe. The larger the focal length is, the larger the laser focused spot will be. For the same laser, the larger the spot area is, the smaller the energy density will be, the greater the energy consumption of excitation will be, the thicker the lines will be, and the effect will be very shallow. Therefore, the larger the field mirror is, the better the effect will be, Be sure to choose the right one.
3: The third is the focal length. In the case of the same format, the shorter the focal length, the better, because the field mirror with short focal length makes deep and thin lines when marking. However, the shorter the focal length is, the smaller the focal depth will be, and the higher the requirements for the flatness of the product surface will be. Therefore, some products with radians or uneven surfaces are not suitable for marking with a field mirror with short focal length. At this time, you can use a long focal length for marking, but the larger the focal length is, the lighter the marking effect will be. You can also choose a higher power laser to use with it.
4: The fourth is the light spot. Generally, the galvanometer of the marking machine is 12 light spots, so 12 light spots can be selected for the field mirror. However, some people buy a field mirror to make a galvanometer welding machine. The galvanometer of the welding machine is generally 20 facula, 25 facula, 30 facula, 36 facula and other large facula. The field mirror with small facula cannot bear the high-power galvanometer welding machine and will burn off. Therefore, the selected field mirror must be matched with the facula.
