With new technologies such as industrial robots and industrial Internet, new processes such as robot electrostatic spraying, laser surface treatment, ion implantation and molecular film are gradually promoted in the automotive parts surface treatment industry, and the overall technical level of the industry will enter a new level.
Cluster distribution of automobile parts surface treatment enterprises
At present, there are more than 1000 enterprises engaged in the surface treatment of auto parts in China. The enterprises are mainly distributed in the Bohai Sea, Yangtze River Delta, Pearl River Delta and central Hubei, showing a certain cluster effect.
In terms of enterprise scale, the industry is mainly small and medium-sized enterprises. Among the enterprises engaged in automobile parts surface treatment, most of them have a registered capital of less than 10 million yuan.
At present, the surface treatment technologies of domestic auto parts surface treatment enterprises are still dominated by traditional electroplating, electrophoresis, phosphating, passivation blackening, carburizing and nitriding, and the application proportion of new surface treatment technologies such as high-energy beam surface strengthening, plasma spraying, surface nano strengthening and surface composite strengthening technologies is still low, The overall technical level of the industry still has great room for improvement.
