What Is Sheet Metal?

Sheet metal, a processing technology, has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching / cutting / compositing, folding, riveting, splicing, Molding (such as car body). Its distinctive feature is the same thickness of the same part.

Sheet metal has light weight, high strength, and electrical conductivity (can be used for

There are many sheet metal materials suitable for stamping. Sheet metal materials widely used in the electronics industry include:

Ordinary cold-rolled sheet SPCC SPCC refers to the continuous rolling of steel ingots into cold-rolled mills to form steel coils or sheets of required thickness. There is no protection on the surface of SPCC, and it is easily oxidized when exposed to the air, especially in humid environments.

In order to meet the requirements of product functions and appearance, the design of sheet metal should ensure that the stamping process is simple, the production of stamping dies is easy, the quality of sheet metal stamping is high, and the dimensions are stable. For detailed sheet metal design guidelines, please refer to "Part Structure Design Processability" and "Product Design Guide for Manufacturing and Assembly" published by the Machinery Industry Press.

With the rise of China's manufacturing industry, China's sheet metal and production industries have developed rapidly. In 2009, there were 30,000 enterprises (workshops) and 1.8 million employees in the industry. The annual production of sheet metal parts was about 42 million tons, and the total sales reached 500 billion yuan.

Generally speaking, the industry started late, the scale of enterprises is generally small, and the lack of production and technical personnel makes it difficult to form the core competitiveness of enterprises. The market competition is becoming increasingly fierce and does not have the strength to compete with international multinational companies.

The development of the sheet metal processing industry must conform to the design, manufacturing, and consumption concepts of low-carbon, environmental protection, and energy-saving materials. Production should be flexible and sophisticated, and enterprises should be specialized and globalized.
