As we all know, laser marking machine can be applied in many ways. Today, the editor of REDSAIL laser marking machine will briefly introduce the application of laser marking machine on mobile phone charging bank.

Mobile power supply for mobile phone is an electric energy storage of portable charging device that integrates power supply and charging functions. It can charge or standby power for mobile phone and other digital devices anytime and anywhere. Generally, polymer lithium ion cells are used as storage carriers.

With the development of mobile power, users are no longer satisfied with being able to charge, and more users pursue safety and personality. Some mobile power supplies on the market have worked hard on the shell. Manufacturers no longer only put their own logo information on the shell of mobile power supply, but also put some interesting patterns and words on it to increase consumers' desire to buy.

For the traditional silk screen products, the marked pattern and text information are not only of low precision, but also easy to fade and fall off, which brings the appearance deficiency to the mobile power supply. Therefore, many manufacturers have adopted a new marking technology - laser marking technology.

Laser marking technology is one of the application fields of laser processing. Laser marking is a marking method that uses a high energy density laser to locally irradiate the workpiece, vaporize the surface material or produce a chemical reaction of color change, thus leaving a permanent mark.

The basic principle of the laser marking machine is that the laser generator generates a high-energy continuous laser beam, and the focused laser acts on the substrate material, making the surface material melt instantly, even vaporize. By controlling the path of the laser on the surface of the material, the required graphic and text marks are formed.
