Laser Marking or Engraving
Everlucky provides laser or engraving work of the logo or PN on the parts for customers.
Principle
Laser marking technology is one of the largest application areas 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, and the size of the characters can range from millimeters to micrometers, which has special significance for the anti-counterfeiting of products.
Fundamental
- The basic principle of laser marking is that a high-energy continuous laser beam is generated by a laser generator, and the focused laser acts on the printing material to instantly melt or even vaporize the surface material. By controlling the path of the laser on the surface of the material, the formation of Graphical markup required.
- Laser marking is characterized by non-contact processing, which can be marked on any special-shaped surface without deformation and internal stress of the workpiece, and is suitable for marking materials such as metal, plastic, glass, ceramics, wood, and leather.
- Lasers can mark almost all parts (such as pistons, piston rings, valves, valve seats, hardware tools, sanitary ware, electronic components, etc.), and the markings are wear-resistant, the production process is easy to automate, and the marked parts are less deformed.
- The laser marking machine adopts the scanning method to mark, that is, the laser beam is incident on the two mirrors, and the mirrors are rotated along the X and Y axes by the computer-controlled scanning motor, and the laser beam is focused and falls on the marked workpiece, thereby forming a traces of laser marking.
- In the Pearl River Delta, Hong Kong and Taiwan regions, laser marking is called laser laser processing according to the English (Laser) transliteration of laser.
Advantages
- 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; 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 needed. As long as the laser can work normally, it can be continuously processed 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.
