Many materials can be cleaned in laser cleaning, and the fields of application are also vast. This post is the ultimate guide to the application of laser cleaning machines. Read and understand which industries are suitable for laser cleaning machines.

Laser Cleaning Principle

Laser cleaning technology uses laser beams to irradiate the surface of workpieces to peel off or vaporize surface dirt and rust.

Laser Cleaning Applications

Laser cleaning technology is an advanced cleaning technology. Thanks to the characteristics of efficiency and environmental protection, it will be applied to various fields in the future. Next is a complete guide about cleaning laser machine applications. If your company also needs this business, let’s see if it is appropriate.

Electronics Industry

The electronic industry requires high precision to decontaminate. Removing oxides using laser rust removal for this field will not damage the pin. Moreover, a needle only needs to be irradiated once, and the efficiency is very high. Besides increased efficiency, the laser can remove oxides to ensure the best electrical contact.


  1. High pollution accuracy
  2. Efficient
  3. Will not cause damage


The traditional cleaning method of molds includes sandblasting, ultrasonic, or carbon dioxide cleaning. The conventional cleaning method uses chemical solvents, heat first, cool down, and finally cleans. This cleaning method takes time and damages the original mold’s accuracy. However, the laser cleaner machine was cleaned conveniently and did not produce toxic gases. This safe working environment also the protection of staff.


  1. Save time
  2. Avoid mold damage
  3. Save raw materials
  4. Safe working environment


Laser cleaners can clean the dark spots and stains of buildings and stone monuments. Laser cleaning can preserve the appearance of ancient buildings. Currently, the cleanliness of modern skyscraper facades is becoming increasingly prominent. The clean laser machine provides a good solution for cleaning buildings through up to 70 meters of optical fiber. It can effectively clean all kinds of pollutants on various stones, metals, and glass. The most important thing is that it is several times more efficient than traditional cleaning methods.


  1. No damage to buildings
  2. High cleaning efficiency


The surface of the plane needs to be repainted periodically. But the old paint needs to be removed entirely before painting. Traditional mechanical clear color is easy to cause damage to the metal surface of the plane. Damage will bring hidden dangers to flight safety. Cleaning with a laser cleaning machine can completely remove the paint layer on the surface of an airplane within two days. And will not damage the metal surface.


  1. No damage to the aircraft
  2. Short time

Precision Machinery Industry

The traditional cleaning method is chemical cleaning for degreasing and cleaning in the precision machinery industry. This cleaning method leaves chemical residue. Esters and mineral oil can be completely removed with a laser rust removal tool. Moreover, laser cleaning is non-contact and will not damage the part’s surface.


  1. No chemical residue
  2. Non-contact
  3. No damage to parts

Nuclear Power Plant

A high-powered laser beam is directed inside the reactor to remove radioactive dust directly. This is the principle of laser cleaning pipes in nuclear power plant reactors. This process can be operated remotely, effectively reducing health damage to operators.


  1. Remote operation
  2. Safe, harmless


Laser cleaning technology is widely used in the maintenance of weapons. Laser cleaning tools can efficiently and quickly remove rust and pollutants. It enables the automated selection of removal sites. The cleanliness of laser rust cleaner is higher than that of the chemical cleaning process. Moreover, laser cleaning has almost no damage to the object’s surface. You can set the parameters to form a dense oxide protective film on the metal surface. This protective film can improve the strength and corrosion resistance of the object’s surface.


  1. Efficient and fast
  2. Automatically calibrates the cleaning position
  3. No damage to the surface of the object

Laser Cleaning Advantages

Why is laser cleaning technology becoming more and more popular nowadays? There are some defects in the traditional cleaning method.

Cleaning Methid
Pros and Cons
Mechanical Friction Cleaning
High cleanliness, but easy to damage the substrate.
Chemical Corrosion Cleaning
Serious pollution.
Liquid Solid Jet Cleaning
The flexibility is high, but the cost is high, and the waste liquid treatment is complicated.
High-frequency Ultrasonic Cleaning
The cleaning effect is good. However, the cleaning size is limited, and the workpiece needs to be dried after cleaning.

In the past 40 years, laser cleaning technology has developed rapidly. Laser cleaning technology is indispensable in today’s industrial production and material science fields.

Environmental Advantage

Laser cleaning is a green cleaning method. It does not need to use any chemicals or cleaning fluid. The cleaned waste is solid powder. These waste materials are small, easy to store, recyclable, have no photochemical reaction, and will not produce pollution. So, laser cleaning can solve the environmental pollution problem caused by chemical cleaning.

Effect Advantage

The traditional cleaning method is often contact cleaning. This cleaning method has a mechanical force on the surface of the cleaned object and will damage the object’s surface. Laser cleaning is non-abrasive, non-contact, has no thermal effect, and will not damage the substrate.

Control Advantage

The fiber cleaning machine can be operated remotely. Moreover, the laser cleaning method can clean the parts that are difficult to reach by traditional methods. Use in some dangerous places can ensure the safety of personnel.

Convenience Advantage

Laser cleaning can remove all types of contaminants from the surface of various materials. It achieves a level of cleanliness that cannot be achieved with conventional cleaning. Moreover, the pollutants on the material’s surface can be selectively cleaned without damaging the material’s surface.

Cost Advantage

Laser cleaning is fast and efficient, saving time. Although the initial one-time investment in purchasing laser cleaning machines is high, the system can be used stably for a long time. The operating cost of the machine is low, and more importantly, it can be easily automated. The cleaning efficiency of a single unit is 8 square meters, and the operating cost per hour is about 5 degrees of electricity. That is, the cleaning cost is 40 cents per square meter. In addition to the initial cost, 40 cents per square meter in the later period.

Technology Advantage

  • Cleans or removes surface paint quickly and cleanly
  • Accurate cleaning and paint removal results
  • No damage to the substrate
  • Fast return on investment
  • No sandblasting grit or chemicals required
  • Equipment use without erection time
  • No noise
  • Little need for maintenance

As a new cleaning technology, laser cleaning has many advantages. Such as environmental protection and high efficiency. It is one of the leading development directions of today’s laser technology and has broad application prospects. Laser cleaning technology has been well applied in aerospace, rail transit, automobile manufacturing, steel manufacturing, the electronics industry, medical treatment, and restoration of cultural relics.

The above is the application and advantages of laser cleaning. Laser cleaning technology has significant economic benefits and effects compared to traditional cleaning.
