Sheet metal is a steel handicraft processing technology that belongs to the cold working process and belongs to the steel processing and manufacturing industry. According to the international definition of sheet metal, sheet metal is a relatively detailed cold working process for metal plates, ultimately formed through processes such as shearing, cutting, and piecing together. For example, people buy thick steel plate shells on the street, which means they are made according to sheet metal processing technology. Sheet metal belongs to thin steel, so its quality is relatively light. Sheet metal processing is based on cold working technology, therefore it has a high compressive strength and is very hard. In addition, sheet metal belongs to steel and has good conductivity according to the current. Compared with other steel processing methods, the price has a very good cost-effectiveness. Sheet metal processing is widely used. Sheet metal processing is used to manufacture high-precision parts for electronic and electrical industries, boost the communication industry, and manufacture automotive casings for the automotive industry. In addition, it is also used for the production and processing of medical machinery. In other words, some of the very extensive main uses of sheet metal processing have brought a lot of convenience to people's production, clothing, food, housing, and transportation.
