How is the effect of 15W UV laser cold processing plastic

Contrary to the traditional method, the UV laser marking machine is very fast and accurate in laser processing, the graphics can be customized by computer programming, and it is environmentally friendly and healthy, with low consumables. In many applications, UV has better marking effect on plastic materials. Compared with other types of lasers, when using UV lasers, black marking can be achieved by selectively carbonizing the lower layer of the plastic surface.

The energy of the ultraviolet laser output of the short wavelength ultraviolet laser stimulates the photochemical reaction of the material, and the ultraviolet laser avoids excessive heat output. When processing some sensitive materials, such as plastics containing flame retardants, the ultraviolet laser can achieve high resolution Mark with the best surface quality and the fastest machining speed. Compared with infrared and green lasers, ultraviolet lasers do not require expensive laser-sensitive additives during material processing, and can achieve significantly faster processing speeds and better marking quality.

Marking on plastic electrical switches generally changes the color under the surface of the material. When using a UV laser, black marking can be achieved by selectively carbonizing the subsurface of the plastic. The input of heat energy is limited to a small designated area, so that the marking content and the background material are clearly distinguishable and easy to identify. Usually the wavelength of the UV marking machine is 355nm. It provides a new solution for marking plastic electrical switches. In addition to the characteristics of general marking machines, UV laser marking is faster, and the fastest marking speed can reach 3000 characters/second.

Ultraviolet laser marking machine uses its cold processing effect to show its talents on plastic materials. Whether it is a cold light source or a hot light source, it must be admitted that laser processing technology is more and more recognized and applied.
