Sheet metal processing products have the characteristics of light weight, high strength, good conductivity, low cost, and good mass production performance. It is widely used in electronic appliances, communications, automotive industry, medical equipment and other fields, such as computer cases, mobile phones, MP3 and other products, sheet metal is an essential part. With the application of sheet metal processing more and more widely, the requirements for sheet metal processing are getting higher and higher. In fact, the overall requirements for ordinary sheet metal processing parts are not very high, but more attention is paid to the assembly effect; while the requirements for sheet metal precision processing must be strictly implemented in accordance with tolerances. If the tolerance is exceeded but can still be assembled, it is still determined to be unqualified, and its tolerance requirements are one level higher than the conventional standards, so the overall requirements for sheet metal processing will be higher and stricter.

Due to the wide application of sheet metal processing products, its downstream fields include almost all manufacturing industries, mainly including communication electronics industry, automobile manufacturing industry, motorcycle manufacturing industry, aerospace industry, instrumentation industry, home appliance industry, etc, metal forming parts of all kinds of mechanical and electrical products are mostly produced by sheet metal process. Among them, stamping technology is suitable for mass production, while CNC sheet metal processing technology is suitable for precision production.

Although China's sheet metal processing industry has integrated into the global market and occupied a certain market share among many customers around the world, there is still a certain gap between the technical level and the relevant enterprises in developed countries. The key gap lies in the weak technical service capacity, which cannot fully and timely meet the various needs of customers.

With the continuous improvement of the internationalization of the industry, the leading enterprises in the industry gradually realize the gap between themselves and the international advanced level, and gradually establish a complete manufacturing service system. The gap between these enterprises and related enterprises in developed countries in terms of technological level has been significantly narrowed. Industrial technology mainly includes manufacturing technology and service technology.
