There are many products on the market have the two-dimensional code identification, the quality of the two-dimensional code identification directly affects the scanning and reading results, these two-dimensional code after the identification of many testing institutions and have certain requirements for the level, laser marking machine as the leader of the identification industry, can the two-dimensional code identification pass the A-level detection?

     As a laser equipment manufacturer with 19 years of optical research experience - Lansu laser, in the research of marking machine can be said to be proficient, our marking machine uses new laser technology at home and abroad, can achieve a lasting two-dimensional code on most of the industrial or commercial materials. The laser of 355nm, 1064nm and 10640nm is used to carve according to different materials, which is the trace carved by the evaporation of the surface material to expose the deep material of the material, or by the physical change of the surface material caused by light energy.

     Class A two-dimensional code refers to the two-dimensional code with module positioning accuracy of 0.2mm and resolution of 200DPI, such two-dimensional code is not only high in clarity, but also can be read quickly and accurately by most two-dimensional code scanning equipment. Whether it is in warehouse management, production line tracking, or in the anti-counterfeiting identification of products, the two-dimensional code identified by the laser marking machine has played a huge role.

     Of course, not all laser marking machines can achieve A-level marking, there is no high-quality laser, fine identification, operating technology and other detection to achieve A is more difficult, so it is very important to find the right manufacturer.
