Precision sheet metal customization is a comprehensive sheet metal cold drawing process (generally less than 6mm), including cutting, punching/cutting/compounding, folding, welding, riveting , splicing, forming (such as car body). Its distinguishing feature is that the same part has the same thickness and thinness. This is called sheet metal processing. The sheet metal parts referred to by different industries are generally different and are mainly used for assembly.

Sheet metal parts have the characteristics of light weight, high strength, strong conductivity (suitable for electromagnetic shielding), low cost, and good mass production performance. They are widely used in electrical and electronics, communications, automotive industry, medical machinery and other industries. For example, sheet metal parts are indispensable parts in computer cases, mobile phones and MP3 players. As the application of sheet metal parts becomes more and more common, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must master the design skills of sheet metal parts, so that the designed sheet metal parts can not only meet the requirements of product function and appearance, but also make stamping manufacturing simple and low cost. Generally speaking, the three key processes in sheet metal fabrication are cutting, punching/cutting and folding sheet metal, sometimes referred to as sheet metal. The word comes from sheet metal in English. Generally, some sheet metal must be constrained by hand or die to plastically deform to produce the desired shape and gauge, while finer parts can be produced by welding or a small amount of machining, such as cigarettes commonly used in households Tubes, tin furnaces and car casings.
