The traditional way of marking is to use silk screen to print on the outside. The screen printing ink has a strong contrast, the dot is not delicate enough, it is difficult to follow the color, the printing effect is not ideal, and the marked information is easy to fade and fall off.
Laser marking is a clean, non-polluting and environmentally friendly processing technology. It has non-contact marking, high marking accuracy, high definition, good permanentness and strong wear resistance. With the market demand, the laser marking machine quickly replaced the silk screen process.
