Application of Laser Cleaning

Laser cleaning technology is a new cleaning technology developed rapidly in the past 10 years. It replaces the traditional cleaning process in many fields with its irreplaceable advantages such as no grinding, non-contact and no thermal effect. Laser cleaning can be used not only to clean organic contaminants, but also to clean inorganic materials, including metal rust, metal particles, dust, etc. It can be used as a manufacturing tool to quickly make various materials look like new. “Beautician”, here are seven common applications for green laser pointer cleaning.

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. Conventional cleaning methods include sand blasting, 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 blue laser pointer cleaning method can be used to clean the light guide to the dead angle of the mold or the portion which is difficult to remove, so that the use is convenient, and the process does not generate toxic gas, and has the characteristics of safety and environmental protection. 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.

Laser cleaning technology also has many advantages in weapon maintenance:
The laser cleaning system can remove rust and pollutants efficiently and quickly;
The cleaning part can be selected to realize the automation of cleaning;
By setting different parameters, a dense oxide protective film or metal molten layer can be formed on the surface of the metal object to improve surface strength and corrosion resistance.
Laser-cleared waste does not substantially pollute the environment.
It can also be operated remotely, effectively reducing the health damage to the operator.

The surface of the aircraft must be repainted after a certain period of time, but the original old paint must be completely 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 burning laser pointer 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.

With the rapid development of the 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 a good solution to the cleaning of the external walls of buildings through optical fibers. Various pollutants on various stone, metal and glass are effectively cleaned and many times higher than conventional cleaning. It can also remove black spots and stains on various stone materials in buildings.

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 astronomy laser pointer to be applied to one pin.

The precision machinery industry often needs to remove esters and mineral oils used to lubricate and resist corrosion on parts. Chemical methods commonly used in the past often have residues. Laser deesterification removes esters and mineral oil completely without damaging the surface of the part. Because the removal of contaminants is done by shock waves, the explosive vaporization of a thin layer of oxide on the surface of the part creates a shock wave that causes dirt removal rather than mechanical interaction.
