Fiber Laser Cleaning Machine

Laser cleaning equipment manufacturers in 2022

At present, in the context of the country’s vigorous promotion of the transformation and upgrading of the manufacturing industry, advanced laser cleaning technology has received more and more attention. Compared with traditional cleaning methods such as sandblasting, chemical cleaning, and mechanical polishing, laser cleaning has many advantages such as no damage to the substrate, micron-level precise control, energy saving and environmental protection, and some traditional cleaning methods will be banned in many countries.

Fiber Laser Cleaning MachineLaser cleaning technology is mainly used in microelectronics, cultural relics protection, mold cleaning, surface treatment and other fields. In the future, this new cleaning technology will be more widely used in the field of large equipment such as aircraft, ships and bridges, as well as in the field of precision paint removal for precision components such as aircraft parts and electrical products.

According to the characteristics of the substrate material, the precision of the substrate surface, the surface roughness and the type of particle contamination, the current laser cleaning methods can be divided into the following two categories.

Laser dry cleaning

The laser is directly irradiated on the surface of the object. After the contaminated particles or surface absorb energy, they leave the surface through thermal diffusion, photolysis, and gasification.

Laser Wet Cleaning

Spray some non-polluting liquid (mostly water, sometimes alcohol) on the surface of the material to be cleaned, then irradiate it with the laser. After the liquid medium absorbs the laser energy, it will produce explosive vaporization that pushes the surrounding contaminant particles away from the material surface. In addition, a so-called laser double cleaning method has also been proposed. The laser energy is absorbed by the base material, and then heated by the adsorbed intermediate medium through thermal convection, and the intermediate medium undergoes explosive vaporization. Driven by high air flow, the particles are separated from the surface of the substrate together with the intermediate medium.

Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid-solid impact cleaning, and high-frequency ultrasonic cleaning, laser cleaning has obvious advantages.

Advantages of Laser Cleaning Machine

environmental protection

Laser cleaning is a “green” cleaning method that does not use any chemicals and cleaning fluids. The cleaned waste is basically solid powder, small in size, easy to store and recycle, and can easily solve the problems caused by chemical cleaning. Environmental pollution.


Laser cleaning can remove various contaminants on the surface of various materials and achieve cleanliness that cannot be achieved by conventional cleaning. In addition, contaminants on the surface of the material can be selectively cleaned without damaging the surface of the material.


The laser can be transmitted through optical fiber, cooperate with manipulators and robots, can easily realize long-distance work, and can clean the parts that are difficult to reach by traditional methods.


The traditional cleaning method is often contact cleaning, which generates mechanical force on the surface of the object to be cleaned, which damages the surface of the object to be cleaned or the cleaning medium adheres to the surface of the object to be cleaned, which cannot be removed, resulting in secondary pollution. Contact makes these problems easy to fix.

low cost

Although the one-time investment in purchasing a laser cleaning system is high, the cleaning system can be used stably for a long time, and the operating cost is low.

From the advantages of laser cleaning, it can be seen that “cleaning” not only means that the effect of laser processing is very clean, but also the processing process itself is a green process. Unlike wet chemical processes, it does not use toxic solvents, avoiding the noise of grinding methods. Additionally, laser cleaning is gentle and the process is significantly faster than other methods. These advantages have been recognized by the automotive industry and others are following suit, as the laser is a versatile cleaning tool.
