The surface treatment industry belongs to the industrial field of supporting processing properties:
The purpose of Dalian Metal Surface Treatment and Environmental Protection Rectification is to make surface treatment enterprises more formal, rather than making them disappear. At present, there are over 15000 surface treatment enterprises in China, among which enterprises above designated size have an annual output value of 100 billion yuan and a processing output of 1 billion square meters. Surface treatment is not only an important processing link in the traditional mechanical industry, but also an important supporting link in the high-end equipment manufacturing industry, advanced information technology industry, and other fields. Its technological level and development level directly determine the quality of the development of other industrial industries. Therefore, the surface treatment industry can be said to be irreplaceable in its future development.
