This Beautician Is A Bit Fierce: Seven Applications Of Laser Cleaning!


Oct 09.2018
Laser cleaning technology is a new type of cleaning technology developed rapidly in recent 10 years. It has replaced the traditional cleaning technology gradually in many fields with its irreplaceable advantages such as non-grinding, non-contact, non-thermal effect and so on. Laser cleaning can not only be used to clean organic pollutants, but also can be used to clean inorganic substances, including metal corrosion, metal particles, dust and so on. It can quickly change the appearance of various materials like magic. It can be called the "beautician" of manufacturing industry. Here are seven common applications of laser cleaning.


1. mold cleaning

Every year, hundreds of millions of tires are manufactured by tire manufacturers all over the world. The cleaning of tire molds in the production process must be rapid and reliable to save downtime. Conventional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, but these methods usually have to be cooled for several hours before moving to the cleaning equipment for cleaning, cleaning time is long, and easy to damage the accuracy of the mold, chemical solvents and noise will also produce safety and environmental problems.


Using laser cleaning method, optical fiber can be connected to the dead corner of the mold or the parts that are difficult to clean, so it is easy to use, and the process will not produce toxic gases, with the characteristics of safety and environmental protection. Laser cleaning of tire molds has been widely used in the tire industry in Europe and the United States. Although the initial investment costs are high, the benefits can be quickly recovered from saving standby time, avoiding mold damage, working safety and saving raw materials.



2. cleaning of weapons and equipment

(1) laser cleaning technology also has many advantages in weapon maintenance.
(2) using laser cleaning system can remove rust and pollutants efficiently and quickly.
(3) the cleaning parts can be selected to realize the automation of cleaning.
(4) By setting different parameters, a dense oxide protective film or metal melting layer can be formed on the surface of metal objects to improve the surface strength and corrosion resistance.
(5) laser removed wastes basically do not pollute the environment.
(6) remote operation can also be carried out to effectively reduce the health damage to operators.


3. cleaning of old paint for aircraft
The surface of the plane will be repainted after a certain period of time, but the old paint will have to be removed completely before it is sprayed. The traditional mechanical paint removal method is easy to damage the metal surface of the aircraft, which brings hidden dangers to the safety of flight. If multiple laser cleaning systems are used, the paint layer on the surface of an A320 Airbus can be completely removed within two days without damaging the metal surface.


4. cleaning of external walls of buildings
With the rapid development of our country's economy, more and more skyscrapers have been built, and the problem of building external wall cleaning has become increasingly prominent. Laser cleaning system provides a good solution for building external wall cleaning through optical fiber. It can effectively clean all kinds of pollutants on stone, metal and glass. It is much more efficient than conventional cleaning. It can also remove the black spots and stains on all kinds of stones on the building.


5. cleaning in the electronics industry
The electronics industry needs high precision decontamination, especially suitable for using laser to remove oxides. Before welding circuit boards, the 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. A needle only needs to irradiate a laser.


6. precision de ester cleaning in precision instrument industry

In precision machinery industry, esters and mineral oils used for lubrication and corrosion resistance are often removed. In the past, chemical methods usually used remained residues. Laser de ester can completely remove esters and mineral oils without damaging the surface of the parts. Because the removal of pollutants is accomplished by shock waves, the explosive gasification of thin oxide layers on the surface of parts forms a shock wave, resulting in the removal of pollutants, rather than mechanical interaction.

The laser cleaning equipment introduced by Gem Laser has the advantages of easy operation, easy automation, no need of chemical reagents, surface cleaning, high cleaning cleanliness, high precision, high efficiency, environmental protection, safety and reliability, almost no damage to the substrate surface, which can solve many difficult problems that traditional cleaning can not solve.
