In our daily life, we can often see the production date, two-dimensional code, traceability code and other marks on household goods, food packaging and so on. If we look carefully, we can see that some traces are very rough, some even appear to be fuzzy and incomplete, generally sprayed with ink. Some traces are particularly delicate and clear, it is difficult to erase, this is a laser marking machine.
Laser marking machine principle
Laser marking is a laser beam on the surface of various substances for permanent marking. The role of marking is through the surface layer of material evaporation to expose the deep material, or through the light energy caused by the surface layer of material chemical and physical changes to "carve" traces, or through the light energy to burn off some substances, showing the pattern and text to be etched.
Advantages of laser marking
1. Wide range of marking: a variety of metal, non-metallic materials can be processed. Especially for high hardness, high melting point, brittle materials for marking more advantages.
2. Speed: laser marking is more than 100 times faster than ordinary marking methods, and can ensure the accuracy of repeated marking.
3. High quality: non-contact processing, no damage to the product, no tool wear, good marking quality. Can realize fine marking, clean and pollution-free. The marking material is affected by oxidation, deformation and thermal expansion of the area is relatively small.
4. Less energy consumption: the laser beam is fine, the processing material consumption is very small, the processing heat-affected zone is small.
5. High degree of automation: high processing efficiency, the use of computer control, easy to realize automation.
