Sheet metal is a comprehensive cold working process for sheet metal (usually less than 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing and forming (such as automobile body). Its remarkable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different and are mostly used for assembly.
Sheet metal parts are products processed by sheet metal technology, and we can't live without sheet metal parts everywhere. Sheet metal parts are made by filament winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging and water jet cutting.
A definition in foreign professional journals can define sheet metal as: sheet metal is a comprehensive cold working process for metal plates (usually less than 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing and forming (such as automobile body). Its remarkable feature is that the thickness of the same part is consistent.
