New application and new technology of laser marking technology in 3C industry

Laser marking technology is one of the largest application areas of laser processing. Laser marking is a marking method that uses high-energy-density lasers to locally irradiate the workpiece to vaporize or change the color of the surface material, thereby leaving a permanent mark. Laser marking can produce a variety of characters, symbols and patterns, etc., and the size of the characters can range from millimeters to micrometers, which has special significance for the fine processing of products. As a modern precision processing method, laser marking technology has obvious advantages over traditional processing methods such as corrosion, electrical discharge machining, mechanical scribing, and printing. The following focuses on introducing several new applications and new processes of laser fine laser engraving on the surface treatment of 3C products.

　　New application one: Laser wire drawing of laptop shell

　　 The current market for notebook computers is growing very fast, the competition is also very fierce, and new processing techniques are constantly emerging. Among them, the laser wire drawing of the notebook shell is the representative of its latest processing technology.

New application 1: Laser wire drawing of laptop shell

　　Through the laser wire drawing process, it not only ensures the firmness of the notebook shell, but also discharges the heat in time. The processing is fine, beautiful and fashionable, and it combines humanity with business and entertainment themes, adding a sense of texture and nobleness.

　　Using Huagong Laser LSD12E large-format laser marking machine to draw and engrave the laptop shell, the speed can reach 1600mm/s, and the maximum speed can reach 10000mm/s. It takes about 7 minutes to complete the engraving of the 14-inch notebook panel with intricately carved and filled patterns. Engraving patterns directly on the aluminum shell, magnesium-aluminum alloy surface, and stainless steel shell: beautiful graphics, neat edges, it is the best process to replace silk screen and knife engraving. After engraving, it is electroplated with silver, and the texture is outstanding.

　　New application 2: Oxygen breaking on the alloy surface of CO2 galvanometer engraving machine

　　The dynamic gathering CO2 galvanometer engraving machine breaks oxygen on the surface of the magnesium alloy, and the notebook heat sink breaks oxygen, which is high in efficiency and no fire. Laser engraving has high precision, reasonable filling method and fast speed.

　　New application three: keyboard translucent marking and plastic parts marking

　　Large-format full-page marking on the notebook keyboard eliminates multiple clamping, ensuring the efficiency of marking. The whole-page marking time can be completed in about 15S.
