Sheet metal is a comprehensive cold working process for sheet metal (usually less than 6mm), including shearing, punching/cutting, folding, welding, riveting, splicing (such as chassis cabinet), forming (such as car body), etc. Its remarkable feature is the same thickness of the same part.

Generally speaking, basic equipment includes shearing machine, laser cutting, CNC punch, bending machine and all kinds of clamp processing and welding auxiliary equipment. Such as: drilling machine, riveting machine, welding machine and so on.

According to different processing methods, it is usually divided into two categories:
Non-die processing: through NCT (CNC punch), laser (laser), folding bed, riveting machine and other processing tools for sheet metal processing process, generally used for sample production, the cost is high;
Mold processing: through fixed mold, sheet metal processing, generally have blanking die, forming die, mainly used for mass production, low cost.
