355nm UV laser marking surveillance camera shell

Surveillance cameras are the core components of security systems in the commercial sector. With the needs of family life, home-level surveillance cameras are gradually entering the homes of ordinary people. Coupled with the rise of smart homes, through the interconnection with mobile phones and mobile terminals, home cameras are given voice intercom, detection, cloud storage and more. The multi-functionality also allows it to have a larger development stage and market space.

The popularity of home surveillance cameras has caused many manufacturers to deploy. How to make your products more recognizable so that consumers can stand out from the dazzling variety of products has become one of the thinking directions of manufacturers.

People rely on clothes and horses on saddles, and it is no exception to use it on the camera casing. The camera casing not only protects the camera, but also acts more like the camera's clothes. A delicate or pleasing casing can instantly set off the beauty of the camera, thereby driving product sales.

Here you can use the black technology of laser marking.

Laser marking technology integrates laser technology, computer technology and mechatronics technology. It is a new type of non-contact, non-polluting and non-destructive marking process. It uses a high-energy density beam to act on the surface of the material to instantly vaporize it. A process that leaves a specific mark, such as discoloration, structuring, engraving, or material ablation. As one of the most widely used advanced manufacturing technologies in laser processing technology, laser marking is widely used, and has gradually spread from the industrial field to products in daily life.

Generally speaking, the shell of the surveillance camera is mainly made of high-strength engineering plastics, and the change of the material surface during laser marking depends on parameters such as the wavelength and pulse width of the laser. In view of the heat-sensitive characteristics of engineering plastics, the wavelength of 355nm ultraviolet nanosecond laser is 355nm, the pulse width is about 25ns, the processing heat affected zone is small, and there is almost no thermal damage, so it is called a cold light source, which plays a role in "cold" processing. It can better protect the material from thermal forces and avoid deformation or burning problems. When marking, the marking line width is very narrow, reaching the micron level, which can mark complex two-dimensional codes, product logos, serial numbers, models and other parameters, and the marking boundary is clearer, the contrast is higher, and the effect is more delicate, which not only increases the aesthetics , and can also endow the mark with anti-counterfeiting and traceability functions, which is conducive to the protection and promotion of brand value.

At the same time, the marking of laser marking is permanent, does not fall off, is resistant to wear and does not change properties over time, which is the main difference from traditional labeling and ink printing.
