What is pulsed laser cleaning?
By definition, pulsed laser cleaning technology uses high-energy pulsed laser beams to act on the surface of objects. Take advantage of the rapid transient high temperature and thermal expansion effects. A cleaning method that removes surface-attached substances.
Pulse laser cleaning technology is usually divided into the following four steps:
- Instantaneous heating: the pulsed laser beam releases a large amount of energy in a short time. The surface of the object is instantly heated to a high temperature.
- Expansion and rupture: due to the rapid expansion of the surface of the object under the instantaneous high temperature state. Attached dirt will further lose its adhesion to the surface. Combined with the effects of thermal expansion, the dirt can easily crack and separate from the surface.
- Cooling and solidification: After the above two steps of treatment, the cleaned surface will quickly cool into a solid. It can be seen that there is almost no secondary adhesion phenomenon in the cleaning effect.
- Precipitation cleaning: the dirt after cleaning is separated in the solution. Dirt is removed from the cleaning surface by sedimentation or filtration.
Therefore, pulsed laser cleaning technology has the advantages of thorough cleaning. High cleaning efficiency. No damage to the surface and so on. Suitable for surface cleaning of various materials.

Does the pulse laser cleaning machine damage the material?
Many people will ask, if the pulse laser cleaning machine is so clean, will it damage the raw materials? In fact, when the pulse laser cleaning machine is cleaning the material, it actually uses the laser to strike the dirt on the surface of the material. Remove it. Because the laser beam has the characteristics of instantaneous high energy. May have some effect on the surface of the material. However, for most common materials, the cleaning process of the pulse laser cleaning machine will not cause obvious damage to the material. The reasons are as follows:
First, pulsed laser cleaners use short pulses of high-peak laser beams. That is to say, the action time of laser energy is extremely short, usually only a few nanoseconds, or even shorter. Such characteristics allow the laser to release high energy in a short time. Act on the dirt with instantaneous high temperature to achieve the purpose of cleaning. At the same time, avoid large-scale thermal damage to the surface of the material.
Secondly, when cleaning, the cleaning parameters should be reasonably controlled according to the material. For example, for metallic materials. It should be based on the characteristics of the surface deposits and the physical properties of the material. Choose the appropriate laser power. frequency. parameters such as wavelength. In order to achieve the purpose of cleaning without damaging the surface. the surface of the material. For fragile materials such as plastics. paper etc. Care should be taken when cleaning and parameters with lower energy should be selected.
Finally, the cleaning process of the pulsed laser cleaning machine will not change the chemical composition and physical properties of the material. Since this cleaning method does not require the use of any chemical solvents. Will not chemically react with materials. Therefore, it can be guaranteed that the cleaned material still has the original chemical composition and physical properties.
Overall, the pulse laser cleaning machine will not cause obvious damage to ordinary materials during the cleaning process. However, detailed adjustments still need to be made according to the characteristics of the material to be cleaned. To protect the integrity and performance of the material to the maximum extent. If necessary, you can send samples to HANTENCNC, and our engineers will test them for you for free. In order to achieve your satisfactory results.

How to identify the quality of a pulse laser cleaning machine?
Because pulsed laser cleaning is a brand new cleaning technology. There are many unscrupulous merchants who use some poor accessories for profit. So today the engineers of HANTENCNC will teach you how to identify the quality of a pulse laser cleaning machine. There are mainly the following five points:
- Equipment stability:
The stability of pulsed laser cleaning machine is the key point to evaluate its performance. It is mainly reflected in the stability of the output power and the stability of the repetition frequency. The output power and repetition frequency of ordinary pulse laser cleaning machines will vary with the ambient temperature. It fluctuates due to factors such as power fluctuations and laser tube aging.
- Cleaning quality:
Cleaning quality is another key point in evaluating pulsed laser cleaners. Cleaning quality is mainly reflected in clarity and speed. A good pulse laser cleaning machine can clean dirt while ensuring that the surface of the workpiece is not damaged.
- Energy consumption:
A good pulsed laser cleaner has low energy consumption. Meet the requirements of environmental protection and energy saving.
- Technical support and after-sales service:
Having high-quality technical support and after-sales service is a necessary condition for choosing a good pulse laser cleaning machine. You can learn about the relevant company background. User evaluation and other aspects to judge whether its technical support and after-sales service are good.
- Equipment security:
Pulse laser cleaning machine is a kind of high energy laser equipment. Has a certain degree of danger. Therefore, it is necessary to choose equipment with higher security. For example, safety measures such as guards and operator safety procedures are required to avoid operator injury.
