Origin and development

Laser cleaning is regarded as a disruptive industrial cleaning technology because of its environmental protection, high efficiency, accuracy, and easy automation.

Laser cleaning was used in Europe in the early days for the cleaning of ancient buildings and cultural relics. With the passage of time, its application has gradually expanded to the industrial field, and in the past 20 years, Western developed countries have carried out mature large-scale applications in the fields of aviation, aerospace, automobiles, large-scale integrated circuits, cultural relics restoration, and high-end molds.

In 2016, the first laser cleaning machine in China came out; In 2018, the domestic laser cleaning machine was still at the 2019-watt level; In 1000, fiber laser technology exceeded 2020W; In 2000, the power of domestic fiber lasers for cleaning will exceed 2021W; In 6000, Shuidi will take the lead in breaking through the <>W laser cleaning machine equipment technology;

In just 6 years, China's laser cleaning industry as a whole has broken through the integrated collaborative control board system, focus tide pool system, edge light control system, beam homogenization shaping system, anti-shake, high tolerance and other technologies, and has taken a big step closer to catching up with the international top level.

Laser cleaning has been included in the Made in China 2025 industry catalog, with the country's increasing attention to environmental protection, laser cleaning will usher in good development opportunities and broad market prospects.

Technological advantages

Laser cleaning can replace traditional cleaning methods such as manual mechanical cleaning, chemical cleaning, sandblasting cleaning, ultrasonic cleaning, and dry ice cleaning. Laser cleaning offers a number of advantages over traditional cleaning methods.

• 
  

  Non-contact cleaning, no cleaning media

  Laser cleaning is the use of high-energy laser beams to irradiate the surface of the workpiece to be cleaned, and remove contaminants from the surface of the workpiece through selective vaporization, ablation, shock wave, thermoelasticity and other actions. There is no cleaning medium during the cleaning process, which can avoid serious substrate damage (particle cleaning) and media residue (chemical cleaning) in traditional cleaning, and reduce the damage of the substrate to an acceptable range.

• 
  

  Green and environmentally friendly

  The soot generated by laser cleaning can be collected by the dust collector and is easy to dispose of, with no secondary products being generated, minimizing the impact on the environment.

• 
  

  Diversified operation methods

  Laser cleaning can be divided into handheld and automatic cleaning. Hand-held cleaning is carried by the operator with a mobile laser cleaning equipment and a hand-held laser head for cleaning. Automatic cleaning integrates the laser cleaning system with manipulators, crawling robots, AGVs and other equipment to achieve precise and efficient cleaning.

• 
  

  Cleans many types of contaminants

  Whether the substance to be removed is organic, metallic, oxide or inorganic non-metal, laser cleaning can remove it. This is an advantage that no other traditional method has, making it widely used in the removal of surface dirt, paint, rust, film layers, etc.

• 
  

  Low operating costs

  Laser cleaning does not use consumables, and the operating cost is advantageous compared to traditional methods.
