Mold Industry

The laser cleaner can realize the non-contact cleaning of the mold, which is very safe for the surface of the mold, can ensure its accuracy, and can clean the sub-micron dirt particles that cannot be removed by traditional cleaning methods, so as to achieve truly pollution-free, efficient and high-quality cleaning.

 Precision Instrument Industry

The precision machinery industry often needs to remove esters and mineral oils used for lubrication and corrosion resistance from parts, usually chemically, and chemical cleaning often leaves residues. Laser deesterification can completely remove esters and mineral oils without damaging the surface of the parts. The laser promotes the explosive gasification of the thin oxide layer on the surface of the part to form a shock wave, which results in the removal of contaminants rather than mechanical interaction.

 Rail Industry

At present, all the pre-welding cleaning of rails adopts grinding wheel and abrasive belt grinding type cleaning, which causes serious damage to the substrate and serious residual stress, and consumes a lot of grinding wheel consumables every year, which is costly and causes serious dust pollution to the environment. Laser cleaning can provide high-quality and efficient green cleaning technology for my country’s high-speed railway track laying production, solve the above problems, eliminate welding defects such as seamless rail holes and gray spots, and improve the stability and safety of my country’s high-speed railway operation. 

Aviation Industry

The surface of the aircraft needs to be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. Chemical soaking/wiping is the main paint stripping method in the aviation field. This method results in a large amount of chemical auxiliary waste, and it is impossible to achieve local maintenance and paint stripping. This process is heavy workload and harmful to health. Laser cleaning enables high-quality removal of paint on aircraft skin surfaces and is easily automated for production. At present, the laser cleaning technology has been applied to the maintenance of some high-end models.

 Ship Industry

At present, the pre-production cleaning of ships mainly adopts the sand blasting method. The sand blasting method has caused serious dust pollution to the surrounding environment and has been gradually banned, resulting in the reduction or even suspension of production by ship manufacturers. Laser cleaning technology will provide a green and pollution-free cleaning solution for anti-corrosion spraying on ship surfaces.

 Weaponry

Laser cleaning technology has been widely used in weapon maintenance. The laser cleaning system can remove rust and contaminants efficiently and quickly, and can select the cleaning part to realize the automation of cleaning. Using laser cleaning, not only the cleanliness is higher than the chemical cleaning process, but also has almost no damage to the surface of the object. By setting different parameters, the laser cleaning machine can also form a dense oxide protective film or metal melting layer on the surface of metal objects to improve surface strength and corrosion resistance. The waste removed by the laser basically does not pollute the environment, and it can also be operated at a long distance, which effectively reduces the damage to the operator’s health.

 Building Exterior

More and more skyscrapers are being built, and the cleaning problem of building exterior walls has become increasingly prominent. The laser cleaning system cleans the exterior walls of buildings well through optical fibers. The solution with a maximum length of 70 meters can effectively clean various pollutants on various stones, metals and glass, and its efficiency is much higher than that of conventional cleaning. It can also remove black spots and stains from various stones in buildings. The cleaning test of the laser cleaning system on the buildings and stone monuments shows that laser cleaning has a good effect on protecting the appearance of ancient buildings.

 Electronics Industry

The electronics industry uses lasers to remove oxides: The electronics industry requires high-precision decontamination, and laser deoxidation is particularly suitable. Component pins must be thoroughly deoxidized before soldering the board to ensure optimal electrical contact and the pins must not be damaged during the decontamination process. Laser cleaning can meet the requirements of use, and the efficiency is very high, and only one laser irradiation is required for each needle.

 Nuclear Power Plant

Laser cleaning systems are also used in the cleaning of reactor pipes in nuclear power plants. It uses an optical fiber to introduce a high-power laser beam into the reactor to directly remove radioactive dust, and the cleaned material is easy to clean. And because it is operated from a distance, the safety of the staff can be guaranteed.

 Summary

Today’s advanced manufacturing industry has become the commanding heights of international competition. As an advanced system in laser manufacturing, laser cleaning machine has great potential for application value in industrial development. Vigorously developing laser cleaning technology has very important strategic significance for economic and social development.
