The Laser Cleaning Machine Application
Jul 10, 2018

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

1. Cleaning of the mold

Every year, tire manufacturers around the world manufacture hundreds of millions of tires. The cleaning of tire molds must be fast and reliable during production to save downtime. Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, but these methods usually have to be cooled in a hot mold for several hours, then moved to a cleaning device for cleaning, which takes a long time to clean and easily impairs the accuracy of the mold. Chemical solvents and noise can also cause safety and environmental issues. The laser cleaning method is very flexible in use because the laser can be transmitted by using an optical fiber; since the laser cleaning method can use optical fiber connection to clean the light guide to a dead angle of the mold or a portion that is difficult to remove, it is convenient to use; No gasification, so no toxic gases will be produced, which will affect the safety of the working environment. The technology of laser cleaning tire molds has been widely used in the tire industry in Europe and the United States. Although the initial investment cost is high, the benefits obtained by saving standby time, avoiding mold damage, working safety and saving raw materials can be quickly recovered.

2. Cleaning of weapons and equipment

Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and contaminants efficiently and quickly, and can select the cleaning parts to realize the automation of cleaning. Laser cleaning is not only more clean than chemical cleaning, but also has no damage to the surface of the object.

3. Removal of old paint of the aircraft

Laser cleaning systems in Europe have long been used in the aerospace industry. The surface of the aircraft must be repainted after a certain period of time, but the original old paint needs to be removed before painting. The traditional mechanical paint removal method is easy to cause damage to the metal surface of the aircraft, posing a hidden danger to safe flight. If multiple laser cleaning systems are used, the paint on the surface of an A320 Airbus can be completely removed within two days without damaging the metal surface.

4. Cleaning of the exterior wall of the building

With the rapid development of China's economy, more and more skyscrapers have been built, and the cleaning problem of the exterior walls of the building has become increasingly prominent. The laser cleaning system provides excellent cleaning of the exterior walls of buildings through fiber optics up to 70 meters long. The solution is that it can effectively clean all kinds of pollutants on various stone, metal and glass, and it is many times more efficient than conventional cleaning. It can also remove black spots and stains on various stone materials in buildings. The cleaning test of the laser cleaning system on the buildings and stone monuments in Shaolin Temple of Lushan Mountain shows that the use of laser cleaning is very effective in protecting the appearance of ancient buildings.

5. Cleaning in the electronics industry

The electronics industry uses lasers to remove oxides: the electronics industry requires high-precision decontamination, and is particularly suitable for laser deoxidation. Before the board is soldered, the component pins must be completely de-oxidized to ensure optimal electrical contact, and the pins must not be damaged during the decontamination process. Laser cleaning meets the requirements of use and is highly efficient, requiring only one laser to be applied to one pin.

6. Pipe cleaning in the nuclear power plant reactor

The laser cleaning system is also used for cleaning pipelines in nuclear power plant reactors. It uses optical fiber to introduce 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 remotely, it can ensure the safety of the staff.

In summary, laser cleaning plays an important role in many fields, and in automotive manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building exterior wall cleaning, cultural relics protection, circuit board cleaning, precision parts processing and manufacturing. , LCD cleaning, chewing gum removal and other fields can play an important role.
