Process of marking black logo on anodized aluminum surface with UV laser

First, we need to understand the properties of anodized aluminum. Anodized aluminum is a material with excellent physical and chemical properties, and its surface usually has a dense oxide film. This layer of oxide film has high hardness, high corrosion resistance and good insulation performance, so it has been widely used in many fields. However, in some application scenarios, in order to meet specific identification requirements, we need to mark its surface.

Ultraviolet laser marking is an advanced marking technology, which uses high-energy ultraviolet laser to burn the surface of materials to form specific marks. The advantages of this technique are high marking resolution, environmental friendliness, and no significant damage to materials. Therefore, for marking black marks on the surface of anodized aluminum, UV laser is an ideal choice.

In the specific operation process, it is first necessary to fix the anodized aluminum workpiece in the precision laser processing equipment. Then, the computer controls the position and trajectory of the laser beam to form the desired mark on the surface of the workpiece. In this process, the power and scanning speed of the laser need to be precisely controlled to ensure the clarity and durability of the marking.

The anodized aluminum surface after UV laser marking will show a distinct black mark. These signs are not only high-definition, but also wear-resistant and corrosion-resistant, and can remain legible for a long time in harsh environments.

In general, UV laser marking technology provides a new solution for the marking of anodized aluminum surface. This technology not only meets various marking needs, but is also environmentally friendly without causing significant damage to materials. With the continuous development of technology, it is believed that this process will be more widely used in the future.
