The laser body is divided into fiber laser marking machine, CO2 laser marking machine, ultraviolet laser marking machine, etc.
The most suitable plastic is CO2 laser marking machine. Of course, fiber laser marking machine can also mark most plastic products. Whether to use a CO2 laser marking machine or a fiber laser marking machine, specific problems must be analyzed in detail.
The material component of the marking product, the scope of the marking, and the thickness of the marking material will all affect the final choice.
Of course, the best way is to experiment. In this way, send the sample to the factory, and the factory will help you to check the marking effect. In any case, profound language has no actual effect and is convincing.
The absorption rate of the laser is a function of the wavelength. Therefore, under the same laser intensity, different plastics will get different quality marks. For example, some colored high-density polyethylene and polycarbonate can obtain ideal marks without adding any additives when using UV lasers; while using CO2 laser marking machines, the engraving will not be good unless special additives are added. However, the general plastic CO2 laser marking machine can be used for marking and the price is also moderate. The ultraviolet laser marking machine is relatively more expensive, but the ultraviolet marking effect will be better.
Laser marking machines that can mark on the surface include optical fiber and ultraviolet. If you want to have a better effect, choose a UV laser marking machine. Of course, CO2 laser marking machines are also available, and CO2 laser marking machines are cheaper.
The fiber laser marking machine can not only mark most plastics, but also metal. You can also try whether the plastics you are processing can be marked with a fiber laser marking machine. If you can, it is also good to buy an optical fiber. After all, optical fiber The price of laser marking machines is now reduced. The scope of application is also relatively wide, because the fiber laser marking machine not only has a good marking effect on some plastics, but also has a very good marking effect on metals.

If you are not bad money and pursue the quality of effects, you can consider UV equipment, which is characterized by heat-affected bottom, small light spot, and no thermal deformation. If it is used for rapid marking on a factory assembly line, you can consider an online laser marking machine to be embedded in the assembly line system to realize automatic marking.
