Application of black laser marking technology on aluminum

With the development of the aluminum industry, everyone's requirements for aluminum products are getting higher and higher. Do you want your products to be unparalleled in anti-counterfeiting capabilities? Do you want to improve product grade and brand sense and increase the added value of the product? Laser marking machine is fast and efficient in aluminum production, and the pattern effect produced by it is fine and beautiful, so it is very popular. In the application of laser aluminum, the most widespread and effective is laser black technology.

 

 

Laser aluminum blackening technology principle

Laser marking is a processing method that uses a high-energy-density laser to irradiate a workpiece, vaporize the surface material or change the color of the chemical reaction, leaving a permanent mark. The laser marking machine black technology is for anodized aluminum. Due to the Nano effect, the size of the oxide particles is nano-level after laser processing, so the light absorption performance of the substance is increased, so that visible light can be absorbed and reflected by the substance. There is very little visible light, so it is black to the naked eye.

 

Aluminum black application

Aluminum black is suitable for various aluminum alloy materials such as alumina, magnesium aluminum, etc., and its application is quite wide. The most common are iPad tablets, mobile phone back cover aluminum for logo and text blackening, and various mobile phone accessories, clocks, aluminum stamping, molds and other products for trademarks, logos, batches, etc.

 

 

Laser processing advantages

1. Permanent: The blackening effect will not fade due to the environmental relations such as touch, high and low temperature, acid and alkali.

2. Anti-counterfeiting: Laser blackening is a physical process. The marked information cannot be altered and has strong anti-counterfeiting properties.

3, low cost: laser black molding at one time, no auxiliary materials and a large number of manpower, low consumption.
