The improvement of sheet metal processing industry is the main evaluation aspect that can best reflect the comprehensive capacity of a country's manufacturing industry. The development of this industry will reflect the improvement of the overall quality of national economic development. China has joined the World TradeOrganization for many years, but the current sheet metal processing industry is still in a mess. The emerging national industry has just started, and its scale is very small. Industrial integration can cope with the impact of foreign enterprises and ensure that national industries have a place in the competition. In the next 5-10 years, in addition to expanding its scale to meet domestic demand, China's sheet metal processing industry also needs to integrate production and supply and demand on the advanced Internet in order to remain invincible and prepare for foreign development faster and better.
With the rise of China's manufacturing industry, China's sheet metal and manufacturing industry has developed rapidly. According to the "analysis report on market demand forecast, transformation and upgrading of the sheet metal processing industry" released by the forward-looking Industry Research Institute, as early as 2012, there were more than 30000 enterprises (workshops) in the industry, with 2million employees and an annual output of about 42million tons of sheet metal parts. In 2016, the sales volume of sheet metal processing industry was about 688.5 billion yuan. However, in general, the sheet metal processing industry started late, the industry scale is generally small, and production and technical personnel are scarce. It is difficult to form the core competitiveness of enterprises. The market competition is becoming increasingly fierce, and there is no strength to compete with international multinational corporations.
At present, the economic benefits of sheet metal processing in China are generally good, and the operating profits of many industrial enterprises are more than 20%. The sheet metal processing industry is mainly engaged in the distribution and processing of automobile, shipbuilding, precision machine tools, precision instruments, communication electronics, elevators and other industries. Most of the partners are large foreign companies (General Electric, Bosch, Otis). With the further deepening and continuation of the cooperative relationship, they have learned advanced technology, process, strict and standardized production environment, production process and other management experience, so that key parts and key technologies can be gradually localized, which correspondingly reduces the procurement of key parts from abroad by foreign-funded enterprises and reduces the production costs of manufacturing enterprise.
The profit level of sheet metal processing industry mainly depends on product quality and processing accuracy, products and value-added services, downstream user enterprises and upstream raw material prices. Therefore, in the future, with the increasing technical content of products in the industry, the impact of raw material price fluctuations on products will gradually decrease, and the change trend of industry profit level will be better. At the same time, the change trend of future profit level will mainly depend on factors such as product quality and accuracy, product value-added services and downstream customer industries. With the rapid development of China's automobile,
communication, rail transit, aerospace, home appliances, medical devices, container head manufacturing and other industries, China has become a world manufacturing center. Sheet metal processing has also achieved unprecedented development. The introduction of foreign advanced equipment has driven the continuous development of equipment and technology.
Fully automatic numerical control equipment has replaced the simple and low precision semi-automatic sheet metal processing equipment in the past. Sheet metal manufacturing technology is developing in the direction of digitalization, integration, intelligence and informatization. The sheet metal process design, which connects the design and manufacturing of sheet metal parts, should also adapt to its development and changes, and continue to improve and perfect.
