What do you know about laser marking technology?

2022-05-13

Laser marking technology is one of the largest application fields of laser processing. Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize or change the color of the surface material, thereby leaving a permanent mark. Laser marking can print various characters, symbols and patterns, etc., and the character size can range from millimeters to micrometers, which is of special significance to the anti-counterfeiting of products. The focused very fine laser beam is like a tool, which can remove the material on the surface of the object point by point. Its advanced nature is that the marking process is non-contact processing without mechanical extrusion or mechanical stress, so it will not damage the processed items; due to The laser focused size is small, the heat-affected area is small, and the processing is fine. Therefore, some processes that cannot be achieved by conventional methods can be completed.


The "tool" used in laser processing is the focused light spot, and no additional equipment and materials are required. As long as the laser can work normally, the Laser Marking Machine manufacturer can continuously process for a long time. Laser processing is fast and inexpensive. Laser processing is automatically controlled by computer, and no human intervention is required during production.


What kind of information the laser can mark is only related to the content designed in the computer. As long as the artwork marking system designed in the computer can identify it, the marking machine can accurately restore the design information on the appropriate carrier. So the function of the software actually largely determines the function of the system.
