"At present, there are about 40,000 production enterprises in the stamping industry across the country, with 2 million employees, annual production of 28 million tons of stamping parts, total sales of 400 billion yuan, and annual consumption of more than 40 million tons of thin steel plates below 3 mm. 40 billion yuan, and 20 billion yuan for newly purchased stamping equipment.” Luo Baihui, secretary general of the International Mould, Metal & Plastic Industry Suppliers Association, said that China’s sheet metal and manufacturing industry has 30,000 companies with 1.8 million employees and annual production of sheet metal parts. About 42 million tons, with a total sales of 500 billion yuan.
Future direction: low carbon, environmental protection, energy saving and material saving
Stamping and sheet metal production involve all aspects of the manufacturing industry. It can be described as a large number and wide variety of shapes and processes. In the past ten years, as my country has become the world's manufacturing center and a major consumer country, stamping and sheet metal industries, one of the basic manufacturing industries, have also achieved unprecedented development.
American model: safe and reliable automated production
Luo Baihui, secretary general of the International Mould and Metal Plastic Industry Suppliers Association, believes that the biggest difference between Chinese and American stamping and sheet metal companies is the level of automation and informatization.
First of all, the closed-loop control automated production adopted by American companies is safer and more reliable, and facilitates the operation and maintenance of the entire production line. Companies have their tooling and mold maintenance workshops. Various sensors are installed or embedded in the molds. The application of these sensors greatly improves the safety and reliability of the entire production line.
Secondly, American stamping and sheet metal companies have high safety awareness. Safety gratings are installed on the presses. When the workers are too close to the presses, the presses will automatically stop to ensure the safety of the workers.
Third, American companies have their own management information systems. The materials supplied by its raw material suppliers have barcodes, and various information about the raw materials will be automatically entered into the production database by scanning them when entering the warehouse. As the raw materials enter the processing process, the host computer of each processing link will automatically enter the processing information into the database, and this information will always be attached to the final product.
