Laser cleaning can be used not only to clean organic pollutants, but also to clean inorganic substances, including metal rust, metal particles, dust, etc. Here are some practical applications. These technologies are very mature and widely used.

Mold cleaning:

Every year, tire manufacturers around the world produce hundreds of millions of tires. In the production process, tire mold cleaning must be fast and reliable to save downtime. Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, but these methods usually must be transferred to the cleaning equipment for cleaning after the hot mold has cooled for several hours. Long cleaning time can easily damage the precision of the mold. Chemical solvents and noise can also cause safety and environmental problems. The laser cleaning method is adopted, because the laser can be transmitted through the optical fiber, so it is very flexible to use; because the laser cleaning method can be connected through the optical fiber to guide the light to the dead corner of the mold or the part that is difficult to clean for cleaning, it is very convenient to use; it is not vaporized, Therefore, no toxic gas will be generated to affect the safety of the working environment. Laser cleaning tire mold technology has been widely used in European and American tire industries. Although the initial investment cost is relatively high, the benefits obtained from saving standby time, avoiding mold damage, safe production, and saving raw materials can be quickly restored. It only takes 2 hours to clean a set of large truck tire molds online. Compared with conventional cleaning methods, the economic benefits are obvious.

The anti-stick elastic film layer on the food industry mold needs to be replaced regularly to ensure hygiene. Laser cleaning without chemical reagents is also particularly suitable for this application.

Old aircraft paint removal:

European laser cleaning systems have long been used in the aviation industry. The surface of the aircraft must be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. Traditional mechanical paint removal methods can easily damage the metal surface of aircraft and bring hidden dangers to safe flight. If multiple laser cleaning systems are used, the paint layer on the surface of the A320 Airbus aircraft can be completely removed within two days without damaging the metal surface.

Building exterior wall cleaning:

With the rapid economic development, more and more skyscrapers are being built, and the problem of cleaning the exterior walls of buildings 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 contaminants on various stones, metals, and glass, and its efficiency is many times higher than that of conventional cleaning. . It can also remove black spots and stains on various stones of buildings. The cleaning test of the laser cleaning system on the Songshan Shaolin Temple buildings and stone steles shows that laser cleaning has a good effect on protecting the appearance of ancient buildings.

Cleaning in the electronics industry:

The electronics industry uses lasers to remove oxides: the electronics industry requires high-precision decontamination, and laser deoxidation is particularly suitable. Before soldering the circuit board, the component pins must be thoroughly deoxidized to ensure the best 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. Each needle only needs to be irradiated once.

Precision deesterification cleaning in the precision machinery industry:

The precision machinery industry often needs to remove esters and mineral oils used for lubrication and corrosion-resistant parts, usually using chemical methods, and chemical cleaning often still has residues. Laser deesterification can completely remove esters and mineral oil without damaging the surface of the part. The removal of contaminants is accomplished by shock waves. The explosive vaporization of a thin oxide layer on the surface of the part forms shock waves to remove dirt instead of mechanical interaction. The material is completely de-esterified and used for the cleaning of mechanical parts in the aerospace industry. Laser cleaning can also be used to remove oil and ester in the processing of mechanical parts.

In summary, laser cleaning plays an important role in automobile manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building exterior wall cleaning, cultural relic protection, circuit board cleaning, precision parts processing and manufacturing and other fields. Liquid crystal display Cleaning, chewing gum residue removal and other areas can play an important role.
