Mobile phones are getting smarter, lighter and thinner. The laser engraving technology has been successfully introduced to the mobile phone manufacturing industry. Compared with traditional inkjet processing, laser engraving has the advantages of high engraving precision, non-contact, durable, anti-counterfeiting and high processing efficiency.

The production information, patent number and other data on the back cover of the mobile phone are very small. According to different requirements, the minimum mark can be 0.1mm. Laser machines easily achieve these results thanks to the small focusing spot. The development of cell phone cases also concerned plastics, anode aluminum, ceramics, metal varnish coatings, glass and other materials. Different types of laser marking machines are used for different materials. For example, with plastics, ultraviolet UV lasers are used, while with anode aluminum and ceramics, fiber lasers are used.

Advantages of laser engraving technology on a mobile phone case: the laser engraving processing is highly reliable. Marked graphics, signs and serial numbers are legible and resistant to abrasion. The processing is non-contact, which prevents damage and deformation. The customer-supplied logo can be quickly transferred to the machine's operating system. The serial number is fully automatically coded.
