Laser Cleaning in The Automotive Industry

As the population continues to grow and the middle class continues to expand, the development of the automobile manufacturing industry is further driven. Today's cars are not only required to be practical, but also economical and beautiful. The pace of updates is increasing day by day. Judging from the current cleaning needs in the automotive manufacturing field, the traditional cleaning process cannot be automated, is very time-consuming, and also causes pollution to the environment. Those who need environmental protection and pollution-free also want high efficiency.

The principle of laser cleaning is to use high-frequency short pulse laser as a cleaning solution for the working medium. The high-energy beam of a specific wavelength is absorbed by the rust layer, paint layer, and pollution layer, forming a rapidly expanding plasma (highly ionized unstable gas), and at the same time generating a shock wave, which turns the pollutants into fragments and is removed.

Among the novel cleaning processes adopted in the continuous innovation of automobile technology, laser cleaning technology uses the characteristics of automated cleaning, selective removal, and high cleaning efficiency to clean various parts of the automobile, such as: automobile wheels, brake pads, hoods, engines, etc. It is powerful for surface rust removal, paint removal, oxide layer removal, oil stain removal, etc. In addition, laser cleaning is very gentle, requires no consumables, and does not damage the surface of the substrate. It can save enterprises a certain amount of labor and consumable costs every year.

In the automotive industry, laser cleaning can replace the traditional cleaning methods of pre-welding and post-welding. It can precisely clean the metal parts welded by auto parts or the metal parts after welding, so as to obtain strong welding and adhesion without gaps and micro-cracks. Combined, it can effectively improve the welding quality of the product, and can also perform precise and precise cleaning on designated areas of automobile parts. The cleaning quality and cleaning efficiency are greatly improved, which has won the satisfaction of customers in the automobile manufacturing market.

Laser cleaning machines can also perform partial cleaning of car hoods. Traditional cleaning methods cannot accurately clean the surface, so most automobile parts now adopt the laser cleaning process, and laser cleaning machines can also be equipped with robots or tooling fixtures. Use automated methods to clean workpiece surfaces. In addition, the operation of the laser cleaning machine is very simple. Even a novice can quickly learn to use it after simple operation training.
