What are the requirements for cleanliness of auto parts?

Since the reform and opening up, with the rapid development of China’s and even the global/global auto industry and the rapid progress of various cleaning technologies for auto parts, auto manufacturers in order to improve the quality of their own cars and improve their market competitiveness, therefore, the cleanliness of the auto parts of the factory. The requirements are getting higher and higher. Therefore, the inspection and control of the cleanliness of the products in the R&D and production process of auto parts manufacturers and suppliers is particularly important. Therefore, the cleanliness inspection has become an inaccessible part of the production of many parts.

In the process of automobile assembly and manufacturing, automakers may cause parts contamination due to air pollutants in the storage and assembly workshops of parts and components adhering to the surface of parts or entering the interior of parts. Our common pollutants are metal iron filings, metal powder, dust, various fibers, and oil stains. If the cleanliness inspection and control of parts and components are not in place, it will have a great impact on the performance and service life of our entire vehicle. The comprehensive feedback from the automobile industry maintenance service market has been analyzed and concluded that the lack of cleanliness control of auto parts is manifested as follows: Early abnormal wear of the engine, premature failure of the automobile braking system and valve body, excessive aging of the steering system, and abnormal early corrosion of the automobile surface.

Generally, car manufacturers focus on cleanliness inspection and control requirements in the process of producing and assembling automobiles.
