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.

The difference between electroplating and electrophoresis in Dalian metal surface treatment:

Metal surface treatment technology can protect and strengthen the surface of workpieces without increasing or increasing too much cost, or repair waste and faulty workpieces, thereby improving the service life and reliability of products, improving the performance and quality of mechanical equipment, and enhancing the competitiveness of products. Therefore, metal surface treatment technology is of great significance for saving materials and energy.

Development trend and direction of metal surface treatment in Dalian:

Dalian metal surface treatment technology is a broad, profound and practical basic technology, as well as a newly emerging frontier discipline. Surface technology originated in ancient times, but only since the beginning of this century, with the extensive research on natural phenomena and the rapid development of industry and science and technology, has a series of improvements, combinations, and innovations been made to traditional surface technology, resulting in a large number of modern surface technologies.

Surface treatment is a process to change the surface of metal materials:

Dalian metal surface treatment is an ancient technology. Since there are humans on the earth, surface treatment is a technology that humans have long mastered. The primitive humans lived a hard life and lived in groups. In order to survive, they made stone tools and used grinding technology to make stone tools have sharp edges, producing a "sharp split" effect. In the Neolithic Age, the stone tools used by the primitive people were grinded and the surface was fine and smooth.
