laser marking machine

The MOPA laser marking machine is a new generation of laser marking machine system developed by using the most advanced laser technology in the world. It uses a fiber laser to output the laser, and then realizes the marking function through a digital high-speed galvanometer system, which is mainly used for replacement Traditional and backward aluminum blackening manufacturing process. Advanced laser processing system can quickly improve quality and production efficiency, reduce energy consumption, and reduce environmental pollution. The aluminum blackening MOPA laser marking machine is indeed a relatively widely used laser equipment. Alumina blackening can also be called aluminum logo laser, laser engraving machine, laser engraving, alumina laser engraving machine, metal laser marking machine.

Laser marking machine marking alumina

The aluminum oxide blackening MOPA laser marking machine has high electro-optical conversion efficiency. It is cooled by air cooling, the whole machine is small in size, the output beam quality is good, and the reliability is high. Many existing aluminum blackenings are processed for anodized aluminum. The principle of aluminum blackening is due to the nano effect. After laser treatment, the size of oxide particles is nanometers, so that the light absorption performance of the material is increased, which makes visible light It is irradiated to the substance to be absorbed, and the reflected visible light is very small, which makes it black when viewed with the naked eye, so it is called alumina black. Among them, the film interference theory is impossible. The interference produces different wavelengths of light according to the thickness of the film, but black is not a wavelength of light, but no light. There is also an oxide color. After searching, the aluminum oxide is white. Among them, the black color in stainless steel is caused by iron oxides.

Aluminum black marking machine can directly mark aluminum with black effect

If the aluminum plate without oxide layer wants to print black characters, the only way is to turn on the high power, which must be above 30W, and burn the aluminum to print the aluminum black characters. Alumina with an oxide layer can be white and black with a laser engraving machine. Aluminum black marking machine can directly mark aluminum with black effect
