1. Laser marking machine is a new marking process
In recent years, with the improvement of the sustainability and practicality of lasers, coupled with the rapid development of computer technology and the improvement of optical devices, the development of laser marking technology has been promoted.
Laser marking machine is a new processing technology developed together with laser welding, laser heat treatment, laser cutting, laser punching and other applications, through the use of high energy density laser beam on the target, so that the target surface undergoes physical or chemical changes, so as to obtain the visible pattern of the marking method, that is, the high energy laser beam is focused on the surface of the material, so that the material is rapidly vaporized, forming a pit, and the laser beam moves regularly on the surface of the material while controlling the breaking of the laser, The laser beam is then processed into a specified pattern on the surface of the material; Laser marking is also a new marking process that is non-contact, non-polluting, and wear-free.
The principle of laser marking can be explained in this way, that is, the computer-controlled focused laser beam with high energy density acts on the surface of the workpiece that needs to be marked according to the predetermined trajectory of mechanical parts, electronic components, instrumentation, etc., so that the surface material can achieve instantaneous vaporization or chemical change to change color, etching out a certain depth or color of text, pattern, etc., so as to leave a permanent mark on the surface of the workpiece.
2. Laser marking non-contact permanent identification
Laser marking is a marking method that uses a high energy density laser beam to act on the target, so that the target surface undergoes physical or chemical changes, so as to obtain a visible pattern, and the firm and permanent nature of the mark produced by the laser acting on the surface of the workpiece is its outstanding feature.
Laser marking machine, also known as (laser typewriter, laser printer, laser marking machine), is an important application of the principle of laser processing, that is, the use of treated laser beam irradiation on the surface of the material, light energy is instantly converted into heat energy, so that the surface material instantly melts and even vaporizes, thus forming a mark.
In recent years, laser marking technology has been applied more and more in the field of printing, laser marking can be applied to a variety of materials including plastic and rubber, metal, silicon wafer, etc., the laser marking machine is simple and easy to operate, as long as you understand the basic computer knowledge, you can operate the laser marking machine; In the marking and printing industry, laser marking has the following characteristics:
1. Permanent; For example, the mark does not fade due to environmental conditions (touch, acidic and alkaline gases, high temperatures, low temperatures, etc.).
2. Anti-counterfeiting; The marks engraved by laser marking technology are not easy to imitate and change, and have strong anti-counterfeiting to a certain extent.
3. Non-contact; Laser marking is a non-mechanical "light knife" processing, which can print marks on any regular or irregular surface, and the workpiece will not produce internal stress after marking, ensuring the original accuracy of the workpiece. It does not corrode the working surface, has no "tool" wear, is non-toxic and pollution-free, and is a clean and pollution-free high environmental protection processing technology.
