Laser Marking Will No Longer Be Monotonous

Laser marking technology has led domestic enterprises to enter the laser processing industry, especially after fiber lasers have been widely used in laser equipment, the laser pointer marking industry has also reached the ‘peak’ of the market. Laser marking patterns are black and white and gray.

As far as the current laser marking process is concerned, only part of the fiber laser can be used to achieve color marking on stainless steel. In order to mark such visual effects, in addition to inkjet and lacquer, you can also use the technology of MOPA pulsed fiber laser, a laser whose pulse width and frequency are independently adjustable. When marking a stainless steel material, the green laser pointer can adjust the laser beam to change the color of the surface layer of the material, thereby obtaining decorative effects with different colors.

Its advantage is that its pulse width and frequency are independently adjustable. Adjusting one of them does not affect other laser parameters, which is not available in Q-switched lasers. And this characteristic brings unlimited possibilities to the color marking of stainless steel. In the actual marking operation, the pulse width, frequency, power, speed, filling method, filling interval, delay parameters and other factors will affect the color effect.

However, because the technology is not very mature or has suffered a lot of limitations, the price is also unacceptable to most manufacturers. Because a color laser marking machine can buy several laser marking machines.

Recently, a certain type of laminated material group has been developed in Germany. The laminated material group includes an outer laminated material and an inner laminated material, wherein the outer laminated material includes a transparent polymer carrier, and one side of the carrier contains an infrared The maximum laser-markable layer of color-absorbing infrared dye in this zone can be used for almost all common marking materials. This technical advantage is different from ordinary laser paper on the market.

A composition that can be used for Laser Engraver color marking and its preparation method also appeared in Japan. The composition components include: 100 parts by weight of a polymer; the content of the laser marking powder is 0.05622 parts by weight; and the content of the temperature-sensitive substance is 0.16210 parts by weight. The preparation method comprises: melt blending the components including the polymer, laser marking powder, and temperature-sensitive substance according to the group distribution ratio. In the present invention, by adding a temperature-sensitive substance and utilizing the heat generated during the laser marking process, the temperature-sensitive substance undergoes thermal decomposition, oxidation and other reactions at a certain temperature. These reactions destroy the original material structure or generate a new substance. At the same time, a new color is generated. This color change is unidirectional and irreversible. After cooling, the original color cannot be restored, so a stable permanent mark can be formed on the product.

Shenzhen Feibo Laser is working on the laser color marking technology. It is believed that the laser color marking pattern will be more complex and diverse in the future. The exquisite decorative effect will give laser marking a wider application space and become a trend of laser processing applications.
