What Is Laser Etching
Laser etching is a process that uses a laser beam to create marks on a surface, by emitting large amounts of energy for a specific period of time. Can be used for a variety of applications including engraving and cutting.
During the laser etching process, the extremely high temperature of the laser beam melts the metal surface upon contact. When melted, the molten material expands, leaving marks on the surface of the material.
How To Laser Etching – Laser Etching Process
Laser etched designs are generated by graphic design software. This graphic design software supports vector files. Once the design is complete, save it as a vector file and transfer it to a laser etching machine for printing. The laser etcher reads out the vector file using a CNC router. It also determines the pattern of laser movement and creates the desired design.
The whole purpose of anodizing aluminum is to convert the surface layer of aluminum into aluminum oxide. This material is more resistant to corrosion and wear than the pure aluminum hiding beneath it.
Although aluminum oxide is actually transparent, some anodization methods produce porous aluminum oxide layers that can be colored with special dyes. Therefore, anodized aluminum is more durable than regular aluminum and will not corrode, scratch, or break. And it comes in a lot of colors to choose from – a lot of advantages
The anodizing process only affects the surface of the aluminum to a depth of 0.1-1.0 mm. This makes the laser etching process, with an impact depth of only 0.25 mm, the best choice for marking anodized aluminum. By comparison, laser engraving has an impact depth of 3mm, which means the laser exposes less durable aluminum beneath the anode layer, making the item more susceptible to damage.
Laser etching and engraving technology is used across a wide range of industries to mark stamps, lettermarks and barcodes. Their techniques are similar, but there are differences.
The main difference between laser etching and engraving processes is the depth of cut. Laser engraving penetrates the entire aluminum material, while laser etching is a shallow cut that only cuts part of the material.
Laser etching is typically used on anodized aluminum because it does not remove the anodized layer. This program can be used for serial numbers, barcodes, or other graphics that need to be displayed but not dark.

Compared with traditional wet etching, laser etching does not directly contact the material surface, CAD drawings are written directly, and no mask is required. Therefore, it is more reliable, has higher yield, better consistency, adjustable etching line width and arbitrary graphics. , this technology has been widely used in industrial production such as touch screens, LCDs, PDPs, e-books, and OLEDs. In other application fields, especially the selective etching of some higher-demand multi-layer materials, other traditional methods cannot achieve it.

Durable, High-Precision Laser Etching Material
Because different lasers have different types, wavelengths, pulse widths, frequencies, powers and other parameters, as well as working environments, their interactions with materials will also be different. Therefore, a specific laser has certain selectivity for materials. In the world There is no universal laser that can handle all processing tasks; fortunately, BE-CU ETCH’s hardware investment covers almost all laser series suitable for precision micromachining, especially multiple ultra-fast lasers with “cold processing” technology , so we are never picky about any material.
