1. Laser marking is a permanent anti-counterfeiting mark

  Laser marking is generally realized in three ways: surface material, coating, discoloration marking. The first two of these three ways can leave a certain depth (≤0.3 mm, depending on the material) on the surface of the product, and the third is because the material itself will change color after chemical reaction after heat.

  Therefore, laser marking has permanent and extremely strong anti-counterfeiting effect, and inkjet printing is generally realized by ink attachment to the surface, so it has certain restrictions on the surface material of the product.

 2. Low cost of laser marking

  Laser marking only consumes water and electricity in use, while inkjet printer consumes ink and diluent.

  If the production of ten thousand products per month, we made a preliminary cost estimate, each product with inkjet printer to mark letters, numbers, or graphics, according to the marking of 10 characters, ink and diluent costs about thousands of yuan per month. Because the cost of an ink dilution system is 1:1 liter ink average price is RMB 1000 yuan (USD 160) ,1 liter diluent average price is RMB 300~600 yuan (USD 47-95), and a bottle of ink needs three bottles of diluent to dilute, calculate the price.

  The equipment purchase cost of laser marking system is not different from that of inkjet printer, and its cost is less. The working state of the system is stable, krypton lamp only needs to be replaced regularly. Usually an imported krypton lamp service life of more than 2000 hours, and the price is only about 2000 yuan (USD 309).

  3.The laser marking method has the concept of environmental protection

 The ink used in the ink printer is butanone, the main component of diluent and cleaning agent is butanone, butanone is volatile and slightly poisonous, and the smell is bad, so long time use will easily cause harm to the health of the operator and also affect the environment of the purification work room.

4.Flexibility of laser code marking

  The laser marking machine adopts professional marking software based on Chinese or English WIN98 operating platform, which can cooperate with automatic production line, receive PLT and BMP graphics files, and support AutoCAD and CorelDraw software. Can mark bar code, two-dimensional code and serial number. The marking function is powerful, can adopt the dot matrix way, also can adopt the vector marking way, the operation is simple, the use is flexible. Inside hang a variety of characters, can be selected. In addition, you can add new characters independently, convenient and flexible, easy to upgrade.

  The ink inkjet printer can only use lattice mode, which is limited by the number of printed lines (four rows of lattice at most). It is difficult to print more complex patterns and multi-digit letters or numbers on the surface of a very small product. Even if it can be printed out, its effect is difficult to distinguish clearly.
