Various Laser Marking Machines and Applicable Marking Materials

Nov 04, 2020

      Different types of laser marking machines have advantages for different materials. This is mainly based on the material's absorption of incident laser light, so that it can be judged whether this material can be marked. A variety of materials can be used to get the best marking effect. Choosing different laser marking machines, only by choosing the correct laser wavelength can the characteristics of the laser marking machine's marking be truly brought into play, and by completing our marking work, can the product be sold well.

 

1. Fiber laser marking machine

   The wavelength is 1064nm, which is mainly used for marking with metal materials, but also for marking some non-metal materials (nonmetals with harder materials and higher ignition points).

2. CO2 laser marking machine

  The wavelength of the laser is 10.64um, which is mainly used for non-metallic materials such as leather, cloth, wood, bamboo products, plastics, rubber, and PVC.

CO21

3. Ultraviolet laser marking machine

  Wavelength is 355nm, totally cold light source, also called cold light machine. Mainly used in the high-end market of ultra-fine processing, with good beam quality, smaller focusing spot, ultra-fine marking, extremely small heat-affected area, no thermal effect, no material burning problem, wide application range, copper removal In addition to the material, other materials are applicable.

4. Green laser marking machine

   The wavelength is 532nm, the semi-cold light source, the heat affected area is small, it is suitable for most metal and non-metal materials, and it makes up for the problem of insufficient detail and poor effect of fiber laser marking for many materials.

 

5. MOPA laser marking machine

      It is a special fiber laser marking machine. Its wavelength is 1064nm, the same as the fiber machine. It is mainly used for marking with metal materials, but also for some non-metal materials (non-metal materials with harder materials and higher ignition points); But it has a function that other types of laser marking machines cannot do, that is, it can perform shallow blackening on aluminum profiles, especially anodized aluminum, so as to achieve visual effects and permanent effects. It is fine and beautiful. The surface of the mark is smooth without bumps. It can also be used to paint colors on metals such as stainless steel.

      Therefore, we must pay enough attention to the choice of laser wavelength and select the appropriate wavelength to complete the laser compliance work. Laser marking machines are now used for more and more applications because they can complete good marking and engraving of patterns and can also guarantee good marking results. From this point of view, the development prospects of laser marking machines It's very good.
