Sheet metal processing is the pivotal technology that sheet metal technicians need to grasp, and it is also an important process of sheet metal product forming. Sheet metal processing includes traditional cutting, blanking, bending forming and other methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technology and new process. Sheet metal processing of parts is called sheet metal processing.
Sheet metal processing usually refers to a comprehensive cold processing process for sheet metal below 6mm, including shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming (such as automobile body), etc. its remarkable feature is the difference in the thickness of the same part. Sheet metal processing industry is closely related to people's daily life. Although sheet metal accounts for only 20% to 30% of metal processing, almost all manufacturing industries will touch sheet metal processing. According to statistics, at present, there are more than 30000 enterprises in China's sheet metal processing industry, with more than 1.8 million employees, an annual consumption of more than 40million tons of sheet metal parts, and a total sales volume of 500 billion yuan.
The sheet metal processing industry is of certain importance to improve the domestic machinery manufacturing industry, communication electronics industry, automobile and shipbuilding industries. With the gradual rise of these industries in China, it also drives the rapid development of the sheet metal processing industry. At present, sheet metal industry clusters have appeared in regions with rapid economic development or regions with prosperous manufacturing industry in China.
In Shenzhen in the Pearl River Delta, Suzhou in the Yangtze River Delta and Cangzhou in the Bohai Sea Economic Zone, there are dozens or hundreds of industry clusters, which once formed a local industry chain. The presentation of the sheet metal industry is mainly to do supporting sheet metal processing for domestic and foreign machinery manufacturing enterprises. Domestic and foreign machinery manufacturing enterprises have cultivated the sheet metal processing industry, and the sheet metal processing industry has promoted the rapid development of machinery manufacturing enterprises.
The sheet metal processing industry in China has developed rapidly, which belongs to a technology-based and capital based labor-intensive industry. As a domestic fundamental industry, the sheet metal processing industry is in an upward development channel with the continuous development of the economy. At present, China's manufacturing industry is in the transition period of structural adjustment and industrial upgrading. The domestic manual sheet metal industry will gradually withdraw from the market, and the stamping sheet metal and numerical control sheet metal will be better developed instead. With the numerous development of world-famous manufacturing multinational enterprises in China, China's position as the world's manufacturing center and major consumer country is becoming increasingly prominent. With the continuous progress of technology and economic development, the demand for sheet metal processing structural parts in various fields will increase from time to time. In the next five years, the industry will still maintain a growth rate of 10% - 15%, and the industry has a broad prospect.
