Advanced Laser Paint Removal Machines | Efficient Paint Stripping

Laser paint removal is a cutting-edge technology that utilizes high-energy laser beams to remove paint from a surface through physical and chemical changes in the paint layer. This innovative method has two categories of laser cleaning methods, including dry cleaning and liquid film-assisted cleaning.

Dry cleaning involves directing the laser beam directly onto the surface of the object to achieve the cleaning effect, while liquid film-assisted cleaning involves covering the object's surface with a layer of liquid film before irradiating the laser beam on the liquid film. This creates an explosive shock wave that acts on the pollutants, resulting in cleaning.

Dry Laser Cleaning Mechanisms

Laser paint removal machine mostly uses dry laser cleaning with two mechanisms of action, namely the ablation effect and the vibration effect. The ablation effect achieves precise, layer-by-layer paint removal and is suitable for special requirements. The paint removal effect depends on the heat accumulation generated by the laser's action on the paint layer, making both continuous and pulsed lasers applicable.

However, one disadvantage of this method is that the paint layer's temperature must reach the melting point or boiling point, requiring higher total laser energy. The high-temperature droplets' splash can also cause safety problems. On the other hand, the vibration effect occurs because the paint layer does not phase during the paint stripping process. The total laser energy required is small, but the paint cannot be peeled off layer by layer, and the paint removal effect depends on the instantaneous heating of the paint layer under the laser's action and the thermal stress generated inside the substrate. This means that only short-pulse lasers can be used.

Advantages of Laser Paint Removal

Laser paint removal is essential in equipment manufacturing and remanufacturing engineering, where the old surface must be removed before electroplating, painting, or spraying is carried out on aircraft and ships, repairing and maintaining equipment such as automobiles and radar systems. Compared with traditional paint stripping methods, laser paint removal machines have several advantages.

Firstly, it is a non-contact cleaning method that transfers energy to the cleaning object in the form of light without mechanical contact. This makes it suitable for accurately removing paint from any position and various sizes, with the laser spot's diameter adjustable from a few tenths of a millimeter to a few centimeters. As a result, it is easy to clean paint with irregular shapes and hidden parts.

Secondly, real-time monitoring allows for the cleaning effect to be judged by monitoring the reflectance spectrum of the material's surface or the surface acoustic wave caused by the laser in real-time. This enables adjustments to be made during the cleaning process and intelligent control to be realized.

Thirdly, laser paint removal is non-toxic and pollution-free, eliminating the need for harmful chemical cleaning agents and introducing additional impurities. It is versatile and reliable, able to remove various types of paint on the surface of various materials and achieve a high degree of cleanliness. Only a small amount of impurities are produced, and simple protection is enough.


In conclusion, laser paint removal technology is an innovative and promising solution for various industries due to its advantages, such as non-contact cleaning, high precision, real-time monitoring, non-toxic and pollution-free, versatility, reliability, and low operating and maintenance costs. With the increasing demand for environmental protection and efficiency improvement, laser paint removal machine is expected to become the mainstream paint removal method in the future. This cutting-edge technology has revolutionized paint stripping, making it more efficient and eco-friendly.
