Anodized aluminum refers to the plating of a layer of dense aluminum oxide on the surface of aluminum and aluminum alloys, which can prevent material oxidation, improve the corrosion resistance of aluminum alloys, increase the surface hardness and wear resistance of aluminum alloys. And it can be dyed by electrolytic coloring which to enrich product appearance colors. So it is often used as the preferred material for the shells of 3C products such as mobile phones, tablet computers, and notebooks.

Nowadays, the supplier would put brand logo on the surface of the products.On the one hand, they can show their products , one the other hand, it can be functioned as anti-counterfeiting.

The marking of anodized aluminum shells of traditional products is to remove the anodic oxide layer and leak the silver-white effect of the aluminum substrate, or to print a black effect on the surface of the anode layer to form the brand logo.While the anodized aluminum mirror (polished) is a new type of application in the marking field, which is difficult and the effect is high-end.It is mainly applied into the logo marking of the shell of 3C products such as notebook computers, instead of the traditional sticking mirror stainless steel sheet technology.

Marking while/black color with traditional technology

Mirror effect with new technology

Technology analyse and guidance

1. Laser polished mirror effect, the shading is required to be completely smooth, without streaks and graininess;

2. Need to cooperate with high-speed galvanometer to ensure sufficient polishing times and uniform effect consistency;

1. The filling is tight to achieve full polishing and higher brightness.

Benefits and advantages:

1. High power and high quality laser output, high electro-optical conversion efficiency;

2. The mode can be switched and different processing tasks can be processed at the same time;

2. Can be directly integrated into user equipment.

Processing methods: precision machining, fine welding, metal/non-metal fine cutting, etc.

Application industry:power battery, aerospace, power grid, 3C electronics, etc.
