Spraying can protect automobile sheet metal parts

There are two kinds of surface treatment methods commonly used in the processing of automobile sheet metal parts: electroplating and spraying. Electroplating is divided into galvanizing, nickel plating, chromium plating, etc. the main purpose is to form a protective layer of metal or alloy on the surface of sheet metal workpiece by using the principle of electrolysis, which plays a role of protection and decoration. Spray can be divided into spray painting and powder spraying. After the material parts are pretreated, the spray gun gas is used to disperse the coating into uniform and fine droplets, which are sprayed on the surface of the body work piece to form the coating on the surface of the work piece, and then heated and dried. Spraying can protect the workpiece. In addition to the above two methods, there are some other surface treatment methods, such as anodizing, chromate, wire drawing, sandblasting and oxidation.

The National Bureau of statistics has made a Statistics recently. There are more than 10000 enterprises of certain scale in the auto parts industry in China, and some small supporting enterprises are not included. Therefore, the total number of auto parts industry in China is about 100000, so such a huge market scale is not affordable for all countries, but why China has zero auto parts? The main reason why the parts industry can't develop is because of the uneven quality of products, which is also a period that China's auto parts must go through.

The rapid development of China's automobile industry in recent years is also due to the gradual improvement and subdivision of China's standards in the automobile parts industry. Part of the reason is that the implementation of the mechanism has been withdrawn, so those suppliers who rely solely on fake and inferior products in the market will be more difficult to integrate into the market in the future. The market threshold for auto parts will be higher and higher, and will be eliminated by the market gradually.

In recent years, we should all see that the independent brand of our country is constantly improving, the key core parts are also rapidly improving, the sales volume of the top 100 parts enterprises in our country is also growing, and the R & D investment and institutions are improving, which can fully show that our country has made great progress in automobile parts. This is a fact that cannot be ignored. 。

I believe that in the next few years, the development of auto parts industry will become a global investment industry. If it is through a global investment, we can solve the contradiction between supply and demand in our domestic market, which is surely no better, we can reduce the competitiveness of enterprises to a certain extent. It can also help our country to expand the overseas development of auto parts, increase a certain market share, and increase the popularity of state-owned enterprises.
