With the widespread application of fiber lasers in laser equipment, the laser marking market has also experienced unprecedented prosperity. However, the marking patterns we see in daily marking products are basically black and white and gray. From the existing laser marking process, only some fiber lasers can carry out color marking on stainless steel.

When the laser marks the stainless steel material, the color of the surface layer of the material is changed by adjusting the laser beam to obtain different color decoration effects. The advantage is that the 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. This characteristic increases the infiniteness of stainless steel color marking. Pulse width, power, filling method, delay parameters and other factors will affect the color effect in the actual marking operation.

Because the technology is not very mature, it has limitations, and the price is unacceptable to most manufacturers. A color laser marking machine is several times more expensive than a general laser marking machine. The new laser color marking technology has recently developed a laminated material group developed by Germany. The laminated material group includes an outer laminated material and an inner laminated material. The outer laminated material includes a transparent polymer carrier. A color laser markable layer containing an infrared dye with an absorption maximum in the infrared region on one side. This laminate can be used for almost all common marking materials. This technical advantage is different from ordinary laser paper on the market.

The preparation method includes: 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 in 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.

It is believed that with the continuous innovation of these technologies, laser color marking patterns will become more complex and diverse in the future. The exquisite decorative effect will give laser markings a wider application space and become a major trend in laser processing applications.
