Advantages and application industries of laser cleaning machines

Jun 28, 2022

Laser cleaning is an effective and efficient method for removing rust and oxide layers from the surface of metal materials. The laser with high energy density interacts with specific substances, and the force generated by energy conversion overcomes the bonding force between the material to be cleaned and the substrate. During the process, the pollutants are separated from the material surface to achieve the purpose of cleaning, and the object to be cleaned does not damage itself or the damage is controlled to a minimum range.

The widespread use of laser cleaning equipment stems from the need for a non-toxic, non-abrasive cleaning method that can be used as an alternative to conventional cleaning.

Traditional cleaning methods - mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning, high frequency ultrasonic cleaning, etc.

New cleaning method - laser cleaning machine

1.High efficiency

Under the action of high temperature energy, the deposits are instantly vaporized and evaporated off the surface of the object, and the time required is very short. The traditional cleaning methods, such as ultrasonic cleaning, can only be cleaned after preheating, cooling and other processes, which takes a long time.


Laser cleaning is a "green" cleaning method without the use of any chemicals and cleaning solutions. The cleaned waste is basically solid powder, small in size, easy to store, recyclable, no photochemical reaction, and no pollution. . It can easily solve the problem of environmental pollution caused by chemical cleaning. Often an exhaust fan can solve the problem of waste generated by cleaning.

3.Low cost

Laser cleaning is fast, efficient, and saves time; although the initial investment of a laser cleaning system is high, the cleaning system can be used stably for a long time, with low operating costs, and more importantly, it can be easily automated.

4.More convenient

Laser cleaning can remove various types of contaminants on the surface of various materials, achieving a cleanliness that cannot be achieved by conventional cleaning. Furthermore, contaminants on the surface of the material can be selectively cleaned without damaging the surface of the material.

5.Good effect

The traditional cleaning method is often contact cleaning, which has mechanical force on the surface of the cleaning object, damages the surface of the object or the cleaning medium adheres to the surface of the object to be cleaned, and cannot be removed, resulting in secondary pollution. The non-abrasive and non-contact, non-heating effect of laser cleaning eliminates these problems without damaging the substrate.

6.Convenient control

The laser can be transmitted through the optical fiber, cooperate with the robot hand and the robot, realize the long-distance operation conveniently, and can clean the parts that are difficult to reach by the traditional method. The corresponding pulse frequency, energy and wavelength can be freely selected according to the material to achieve better results

7. High security

Remote operation, no harmful substances and gases. Ensure the safety of operators

8. No wear

The cleaning process is non-contact and does not cause any wear on the base metal surface

Application industry of laser cleaning device:

1.Mold: tire mold cleaning, etc.

2.Weapons and equipment: remove rust, contaminants

3.Aviation manufacturing: the aircraft is regularly removed from the old paint and then sprayed with new paint, and the product parts are degreasing and decontaminated

4.Exterior walls of buildings: Clean the pollutants on various stone, metal and glass, and at the same time remove black spots and stains on the stone.

5.Electronics industry: high-precision removal of oxides. Component pins must be thoroughly deoxidized to ensure optimal electrical contact before board soldering

6.Precision deesterification in the precision instrument industry: removal of esters and mineral oils for lubrication and corrosion resistance

7. Pipe cleaning in nuclear power plant reactor: remove radioactive dust, remote operation, safer

8.Cleaning and protection of cultural relics: For cultural relics, paintings, etc., the washing mechanism is based on the cold ablation effect of breaking the bond, and its thermal impact is small or negligible. No thermal damage to the artwork itself.

9.Derusting of rails, etc.

Compared with traditional cleaning technology, laser cleaning technology has obvious advantages in terms of economic benefits, cleaning effect, safety and environmental protection. It is a new and efficient process technology and has a broader market prospect.
