Using the laser beam of the fiber laser marking machine to mark the surface of the material mainly adopts non-war treatment to save energy. Unlike traditional inkjet printers, marked marks can last a long time, even permanently, without being destroyed. The optical fiber marking machine can eliminate the existence of pollution sources at the source of the entire equipment, which is very green and environmentally friendly. Especially in the case of gradually tightening environmental protection policies, the proportion of applications will definitely increase and become the mainstream marking equipment in the market. The fiber laser marking machine is small in size and has a wide range of applications. It is very convenient and quick for enterprises to use. At the same time, there will be a built-in air cooling mode, which has more obvious advantages in transportation and storage. There are many types of fiber laser marking machines on the market, and we can decide on our own according to production needs. Theoretically, as long as the equipment has higher power, the beam quality will be better, the photoelectric conversion rate will be higher, and the marking will be clearer, which can make the mark exist for a long time and remain unchanged. The short optical path will also eliminate waste and save production cost and improve efficiency. At the same time, compared with other types of marking machines on the market, the fiber laser marking machine not only has lower intermediate power, but also has fewer components such as Q switches and power supplies, and built-in air cooling can save power consumption. Finally, the durability of the fiber laser marking machine is very high, as long as it is used and maintained properly, it can be used for up to 100,000 hours and has a long service life. It is also one of the best in the whole marking equipment, more suitable for enterprises that work for a long time. However, no equipment is perfect and has its advantages and disadvantages, and fiber laser marking machines are no exception. The higher the configuration in the fiber laser marking machine, the higher the equipment cost and the higher the price, which ordinary enterprises may not be able to afford. The market is divided into domestic and imported products, and the price of imported products is higher than that of domestic products. The laser marking machine works with parallel light, which will gather more cores on the surface of the material. The more layers on the surface of a material, the less strong it is.
