Sheet metal parts are sheet metal hardware, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is −

Parts with constant thickness during processing. Corresponding are castings, forgings, machining parts, etc. For example, the iron shell on the outside of the car is sheet metal, and some cabinets made of stainless steel are also sheet metal.

Modern sheet metal processes include: filament power windings, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, bending and forming of sheet metal, die forging, water jet cutting, precision welding .

The surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, because it can prevent parts from rusting and beautify the appearance of the product. The surface pre-treatment of sheet metal parts mainly removes oil, scale, rust, etc. It prepares for surface post-treatment, and the post-treatment is mainly sprayed (baked) paint, sprayed plastic, and plated anti-rust layer.

In 3D software, SolidWorks, UG, Pro / E, SolidEdge, TopSolid, CATIA, etc. all have sheet metal parts, mainly through editing 3D graphics to obtain the data required for sheet metal processing (such as unfolded drawings, bending Line, etc.) and provide data for CNC Punching Machine / Laser, Plasma, Waterjet Cutting Machine / Combination Machine and CNC Bending Machine .
