The automobile manufacturing industry is an industry with a high concentration of new technologies. Today's automobiles are not only required to be practical, but also economical and beautiful. Updates are getting faster and faster. The traditional cleaning method has low efficiency and low precision, and it is difficult to meet the needs of fine cleaning and low-cost processing in the modern automobile manufacturing industry.


During automotive manufacturing, drawing or cooling lubricants and anti-rust oils used can contaminate automotive components and severely degrade the quality of subsequent high-energy joining or bonding processes where welds and bonds in powertrain components must Strict quality standards are met, therefore joint surfaces must be thoroughly cleaned. Traditional cleaning methods are time-consuming, cannot be automated and often have a harmful impact on the environment. The rapid, automated nature of laser cleaning allows for thorough cleaning of surface residues, resulting in strong, void- and micro-crack-free welds and bonds. In addition, laser cleaning is gentle and the process speed is significantly faster than other methods, advantages that have been recognized by the automotive industry.

In the automotive industry, before a car body is overhauled, it is necessary to remove the old paint on the surface so that new paint can be applied. There are many traditional car body paint cleaning methods, mainly mechanical and chemical methods. The mechanical methods include high-pressure water jet paint removal, sandblasting and steel brush polishing, and the chemical methods mainly refer to chemical reagent paint removal. These methods have defects such as high cost, high energy consumption, easy pollution, and easy damage to the surface of the substrate, and have gradually failed to meet the high environmental protection requirements of modern cleaning methods. In response to this situation, many new cleaning technologies have emerged, and laser cleaning, as one of the important methods, has gradually shown its superiority. Selective removal, no substrate damage, and fast cleaning rate are the key favorable factors for laser cleaning paint.


Laser cleaning equipment can not only derust, remove paint, remove oxide layer, remove oil, etc. on the surface of various parts of the car (car hubs, brake pads, hood, engine, etc.), it has powerful functions, and even if you buy laser cleaning equipment in the early stage The one-time investment is high, but laser cleaning can be used stably for a long time, with low operating costs, low maintenance rates, and no other consumables. It can also save a certain amount of labor costs for the enterprise, and the operating cost is low. More importantly, it can easily realize automatic operation.
