With the continuous advancement of laser technology, laser cleaning technology has been understood and applied by more and more customers, playing an increasingly important role in many industries.
However, laser cleaning technology is not omnipotent, and it cannot completely replace some traditional cleaning in some surface cleaning fields.
For example, when cleaning the extruder screws, we only need to remove the solidified plastic,carbonized plastic and rust on shaft, and cannot damage the coating on the surface of the screw.
However, laser cleaning can easily remove pollutants and the coating on the surface of the screw at the same time .
Even if the output power of the laser is reduced and a laser with a large spot is selected, it cannot be guaranteed that the coating will not be damaged. The main reason is related to the characteristics of laser cleaning, because any substance has a certain absorption rate for laser ,sure the coating on the screw is very thin also .
