Metal sheet metal industry is currently lagging behind in improving process equipment

Recently, Qi Junhe, the deputy secretary-general of the China Forging Association, revealed that during the 12th Five-Year Plan period, the average annual growth rate of China's stamping and sheet metal production industries will not fall below 10%. . However, compared with the counterparts in the United States and Japan, the current technical equipment in the stamping and sheet metal industry in China is still relatively backward, and the degree of informatization is relatively low. In order to achieve scale, batch, and even personalized production, it is necessary to continuously improve and adopt advanced technologies. Manufacturing process, etc.

It is understood that the current stamping industry in the country has about 40,000 manufacturing companies, 2 million employees, and annual production of 28 million tons of stamped parts, with total sales of 400 billion yuan, annual consumption of more than 40 million tons of thin steel sheet below 3 millimeters, procurement stamping The mold cost is 40 billion yuan and the newly purchased stamping equipment cost is 20 billion yuan. China's sheet metal and production industry currently has 30,000 enterprises and 1.8 million employees. The annual production of sheet metal parts is about 42 million tons, and the total sales amount reaches 500 billion yuan***.

Future directions: Low-carbon, environmental-friendly, energy-saving materials, stamping, and sheet metal production involve all aspects of the manufacturing industry, which can be described as a wide range of shapes and processes. In the past decade, as China has become a manufacturing center and a major consumer of the world, the stamping and sheet metal industry, one of the manufacturing base industries, has achieved unprecedented development.

The American model: Safe and Reliable Automation When comparing the current status of stamping and sheet metal processing companies at home and abroad, Qi Junhe selected the United States and Japan as reference objects. The biggest difference between Chinese and American stamping and sheet metal companies is the difference in automation and informationization.

First, the automated production of closed-loop control adopted by US companies is more secure and reliable, facilitating the maintenance of the entire production line. The company has its own tooling mold maintenance workshop. Various sensors are installed on or embedded in the mold. The application of these sensors greatly improves the safety and reliability of the entire production line.

Second, U.S. stamping and sheet metal companies have a high sense of security. The safety grating is installed on the press. When the worker is too close to the press, the pressure will be automatically shut down to ensure the safety of the workers.

Again, U.S. companies have their own management information systems. The materials supplied by its raw material suppliers are all provided with bar codes. When they are scanned at the time of storage, all kinds of raw material information will automatically enter the production database. With the raw materials entering the processing process, the host computer at each processing link will automatically input the processing information into the database, and this information will always be attached to the final product.

In addition, although the scale of the US companies is relatively large, the product lines are not very large. They all have fixed buyers, such as Delphi and Ford. Their large production volume is a common feature of them. The U.S. corporate model is the direction for future development of our stamping and sheet metal companies!

Japanese model: process equipment is shocking. In general, Japan's stamping parts are specialized in production, high degree of automation, large-scale production, high product accuracy, humanized management, systemization, and basically all of the mold development, design and processing capabilities. , And generally with its Japanese OEM customers to establish a factory in China.

Compared with Japan's stamping professional companies, China's stamping professional companies still have far-reaching differences in the indicators of their companies, and they need to be improved. In particular, the various production facilities and technological devices that Japanese companies have accumulated in production can be said to be the perfect combination of modern advanced manufacturing technology and human traditional wisdom. All visitors are shocked. Therefore, Chinese enterprises should gradually improve their own manufacturing technology and process equipment in the future.

At present: The introduction of advanced manufacturing industrial equipment Qi Junhe pointed out that the overall situation of China's stamping parts manufacturing enterprises is that the scale is relatively small, the manufacturing equipment is backward, the production is mainly manual operation, the product quality is poor in stability, the production efficiency is low, and it is difficult to achieve mass production and on time. goods. Industry companies still need to improve and improve from the following aspects.

First of all, improve the existing process equipment, work hard and dry, improve product quality, meet the increasing market demand for product quality and supply requirements, and on the premise of ability, try to use advanced manufacturing processes and equipment. Improve the quality assurance system, improve the level of precision, specialization, automation, and information manufacturing to meet the requirements of high-volume and flexible production.

Secondly, enterprises should constantly improve and improve the level of production and sales, continue to reduce their own management costs, and truly manage quality, efficiency, and improve the company's overall competitiveness.

Third, we should pay attention to the construction of the talent team. While constantly introducing the high-quality talents required by the enterprises, we must also pay attention to the re-education and training of the current workforce, keep its technology and management level in step with the times, and at the same time, strengthen international Exchanges and cooperation, understanding the level of domestic and foreign industries, collecting important industry intelligence, broadening the decision-making leadership, and improving the forward-looking and correctness of decision-making.
