Laser cleaning technology<\/a>\u00a0uses nanosecond or picosecond pulsed lasers to irradiate the surface of the workpiece so it can be cleaned. The surface of the workpiece absorbs the high beam laser energy instantly, forming a rapidly expanding plasma (a highly ionized unstable gas), making the \u00a0oil stains, rust spots, dust residues, coatings, oxide layers or other layers vaporized or peeled off, so as to efficiently clean and renew the surface.<\/p>

At present, the cleaning methods widely used in the cleaning industry include mechanical cleaning, chemical cleaning and ultrasonic cleaning, but their application is greatly restricted under the constraints of environmental protection and the requirements of the high-precision market. The laser cleaning machine has obvious advantages in various industries. The main application industries are as follows:<\/p>

  1. Mold industry<\/li><\/ol>

    The laser can realize the non-contact cleaning of the mold, which is very safe to the mold surface. It can ensure its accuracy, and can clean sub-micron dirt particles which cannot be removed by traditional cleaning methods, achieving true pollution-free, high-efficiency, and high-quality cleaning.<\/p>

    1. Precision Instrument Industry<\/li><\/ol>

      The precision machinery industry often needs to remove the esters and mineral oils used for lubrication and corrosion resistance on the parts, usually by chemical methods. But chemical cleaning often still leaves residues. Laser deesterification can completely remove esters and mineral oil without damaging the surface of the part. The laser causes the explosive vaporization of the thin oxide layer on the surface of the part to form a shock wave, which leads to the removal of dirt instead of mechanical interaction.<\/p>

      1. Rail industry<\/li><\/ol>

        At present, all pre-welding cleaning of rails uses grinding wheel and abrasive belt polishing cleaning. The base material is seriously damaged with quite some residual stress not released fully. Also this way results to a large amount of grinding wheel consumables every year with a high cost. Moreover, and serious dust pollution has done severe harm to the environment.\u00a0Laser cleaning<\/a>\u00a0can provide high-quality and efficient green cleaning for high-speed railway track laying production all over the world by solving the above problems, eliminating welding defects such as seamless rail holes and gray spots, and improving the stability and safety of high-speed railway operation.<\/p>

        1. Aviation industry<\/li><\/ol>

          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. Chemical soaking\/wiping is the main paint removal method in the aviation field. This method causes a large amount of chemical ancillary waste and cannot achieve partial maintenance and paint removal. This process is seriously harmful to health.\u00a0Laser cleaning<\/a>\u00a0can achieve high-quality removal of surface paint on aircraft skins, and is easy to realize automated production. At present, this technology has begun to be applied to the maintenance of some high-end models abroad.<\/p>

          1. Shipbuilding industry<\/li><\/ol>

            So far, the pre-production cleaning of ships mainly has adopted sandblasting methods. The sandblasting method has caused serious dust pollution to the surrounding environment and has been gradually banned, which has led to the reduction of production 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 the surface of ships.<\/p>

            1. Military industry<\/li><\/ol>

              Laser cleaning technology<\/a>\u00a0is widely used in weapon maintenance. The laser cleaning system can remove rust and pollutants efficiently and quickly, and can select the removal part to realize the automation of cleaning. Using\u00a0laser cleaning<\/a>, not only the cleanliness is higher than the chemical cleaning process, but also almost no damage would be done to the surface of the weapons.<\/p>

              Laser cleaning<\/a>, as a new and green technology, provides exclusive advantages and benefits to diverse industries. Contact us for more details.<\/p>
