Sheet metal is a comprehensive cold working process for the metal sheets, which thickness is below 6mm. The process of sheet metal including shearing, punching/cutting/compositing, folding, riveting, splicing, forming (such as car body), etc. The notable feature of sheet metal is that the thickness of the same part is uniform.

Generally, the most important steps of sheet metal processing are shearing, punching/cutting/, folding/rolling, welding, surface treatment and so on.

Generally, sheet metal fabricating will make sheet metal deformed plastically by hand or die stamping, then emerge the desired shape and size. Which can also form more complex parts by further welding or a small amount of mechanical processing. For example, the chimneys, iron stoves, and car shells, which commonly used in homes are sheet metal parts.

Sheet metals are thin sheet metal parts, which are parts that can be processed by stamping, bending, and stretching. A general definition is that sheet metal parts has constant thickness during processing.

Sheet metal processing includes traditional cutting, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, and new stamping technologies and other new processing technology. The processing of sheet metal parts is called sheet metal machining.

Modern sheet metal technology includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, roll forming, sheet metal bending, die forging, water jet cutting, precision welding, etc.

The thickness of sheet metal material is 0.5-6 mm, and the maximum width is 2500 mm.
