Overview of the development of China’s sheet metal processing industry

Sheet metal processing is a comprehensive cold deformation processing technology for thin metal sheets such as shearing, stamping/cutting/compositing, bending, welding, riveting, splicing, and forming. Change. Sheet metal processing corresponds to metal processing techniques such as casting, forging, machining, etc., and the metal thickness of its products is usually inconsistent.

According to different processing methods, sheet metal processing can be divided into manual sheet metal, stamping and CNC sheet metal. At present, manual sheet metal is mainly concentrated in the fields of auto repair, art, and advertising; stamping sheet metal is suitable for products with a single variety, large output, small structure, and relatively stable products; CNC sheet metal is suitable for small batches, multiple varieties, and large sizes. product.

The development history of sheet metal technology can be traced back to a long time ago. Starting from ancient copper and iron ware, people used various methods to smelt metal materials, gradually smelted metal sheets, and learned to use some tools to process these metal sheets. This is The prototype of sheet metal technology. Modern sheet metal technology is not very old. The application of stamping equipment and cold stamping dies in the field of sheet metal processing and the popularization of CNC automation equipment are two milestones in the development of sheet metal technology. The former gave birth to stamping, and the latter gave birth to CNC sheet metal.

Industry economic analysis: At present, generally speaking, the economic benefits of sheet metal processing in my country are relatively good, and the operating profits of many industry enterprises are above 20%. The sheet metal processing industry mainly provides processing services for industries such as automobiles, shipbuilding, precision machine tools, precision instruments, communications, and elevators. Most of the partners are large foreign companies (GE, BOSCH, OTIS). With the further deepening and lasting cooperation, we can learn advanced technology, technology and strict production environment and process, so as to gradually realize the localization of key components and key technologies, and reduce production costs for manufacturing enterprises.

As China becomes more and more an international processing and manufacturing center, coupled with the increasing foreign investment, the demand for metal processing continues to increase. In the metal processing industry, the control boxes and machine casings of electrical appliances are usually sheet metal parts, so the demand for sheet metal processing capabilities is also increasing. In addition, for sheet metal processing, sheet metal processing enterprises usually need various mechanical equipment to meet different process requirements. Sheet metal stamping accuracy is generally around ±0.1mm, and bending accuracy is generally ±0.5mm. Therefore, compared with sheet metal processing, the precision is much lower. Therefore, technological progress in the industry has also brought high profits. For example, in sheet metal processing, the profit margin of stamping can generally reach 30%, while the profit margin of laser cutting can reach more than 50%. Overall, the profit level of the sheet metal processing industry mainly depends on product quality and processing accuracy, products and value-added services, downstream user companies and upstream raw material prices. Therefore, in the future, as the technical content of the industry's products becomes higher and higher, the impact of raw material price fluctuations on the products will gradually weaken, and the industry's profit level will improve.

At the same time, the change trend of future profit level mainly depends on factors such as product quality and precision, product value-added services, and downstream customer industries. Enterprises in the industry with strong technical strength, high-end customer resource advantages, and management advantages will gain a higher profit level in the fierce competition in the future.
