The gradual formation and development of automobile sheet metal parts processing industry has greatly accelerated the development of manufacturing industry. The mode of sheet metal processing and distribution breaks the traditional method of simple purchase and transportation, introduces the concept of processing and distribution, which broadens the vision and accelerates the integration of traditional machinery manufacturing and technology.

At present, the development of processing and distribution mode in foreign countries has been very mature, which adopts the integrated service of raw material purchase, cutting (blanking), blanking, bending, welding (assembly), grinding, spraying, packaging and distribution. The emergence of sheet metal processing enterprises avoids the complicated procedures of purchasing raw materials, transportation, etc. of manufacturing enterprises, and saves a lot of human, material and energy of customers; for the customers who are preparing to process the self purchased equipment, they save a lot of internal resources consumption, such as investment in building factories, purchasing equipment, recruiting personnel, setting up inventories, managing materials, etc. Thus, manufacturing enterprises can focus more on the development of new technologies and the research of market trends, and make manufacturing enterprises adapt to the changing market, reducing the risk of enterprises from the market.

Generally, the three important steps of sheet metal processing factory are cutting, punching / cutting and folding. Sheet metal is sometimes used as trigger gold. Generally, some sheet metal is pressed by hand or die to produce plastic deformation, forming the desired shape and size, and further forming more complex parts through welding or a small amount of machining, such as the chimney, special leather stove commonly used in the family, and the car shell are sheet metal parts.

Sheet metal processing is called sheet metal processing. Sheet metal parts are thin metal parts, which can be processed by stamping, bending, stretching and other means. A general definition is the parts with constant thickness in the process of processing, corresponding to forging parts, machining parts, etc. for example, the outer iron shell of the car is sheet metal parts, and some cabinets made of stainless steel are sheet metal parts.

The engineering drawing of automobile sheet metal parts processing also belongs to the category of mechanical drawing. Mechanical drawing is a subject that uses drawings to accurately represent the structural shape, size, working principle and technical requirements of machinery. Drawings are composed of drawings, symbols, words and numbers. They are technical documents to express design intent, manufacturing requirements and exchange experience. They are often called Engineering Languages.
