Fiber laser marking machine application on black marking aluminum products

Metal black marking is generally for stainless steel, and for stainless steel black marking, the ordinary Laser marking machines can do it. But for aluminum, the situation is different.

Aluminum is a kind of metal material with abundant reserves. Due to its excellent properties such as low density, corrosion resistance, low temperature resistance, good heat dissipation and strong thermal conductivity, it is widely used in industry and life.

In recent years, with the development of the aluminum industry, aluminum alloy products not only grow rapidly in traditional applications such as aerospace, transportation, electronics, and construction, but also have good development trends in other new fields. In order to enhance the public awareness of the company and achieve better anti-counterfeiting effects, manufacturers hope to use high technology to mark their products.

The ordinary laser marking machine can mark the aluminum gray or black gray, but it can't be blacker. The mark on copper can't be too black, it is good if it can be clear. It is a special fiber laser marking machine for black marking on the aluminum, also known as the full pulse width laser marking machine.

The principle of full pulse width laser marking machine is to use a special fiber laser to output laser beam for black mark. The electro-optical conversion rate is high, the size is small, and the beam quality is good. The pulse width adjustable mode can be used to adjust the frequency to 400Khz, which can mark the aluminium material directly with black effect. Therefore, the price of the full pulse width laser marking machine is relatively higher than that of the ordinary laser marking machine.

The black marking effect of the full pulse width laser marking machine developed by Shenzhen Sun Laser does not disappear due to the environmental factors such as touch, high or low temperature, acidity and alkalinity. The marked information is unchangeable and has good anti-counterfeiting property. The laser black marking is once forming, no need the auxiliary materials and a large number of people, and the consumption is small.
