Sheet metal processing generally uses materials such as cold-rolled sheet, galvanized sheet, copper sheet, aluminum sheet, stainless steel sheet, aluminum material, etc. The functions are different. As for how to choose, generally need to consider from its use and cost. Sheet metal parts are sheet metal hardware, that is, parts that can be processed by stamping, bending, stretching and other means. A general definition is a part with a 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.

In general, the three most important steps in a sheet metal processing plant are cutting, punching / cutting, and folding.

Sheet metal is also sometimes used as a trigger. The word comes from English platemetal. Generally, some metal sheets are plastically deformed by hand or die stamping to form the desired shape and size, and can be further formed by welding or a small amount of machining. More complex parts, such as chimneys, iron stoves, and car shells that are commonly used in homes are sheet metal. Sheet metal processing is called sheet metal processing. For example, the use of plates to make chimneys, iron drums, fuel tanks, oil tanks, ventilation ducts, elbows, sky gardens, funnel shapes, etc. The main processes are cutting, bending and buckling, bending forming, welding, riveting, etc. Certain geometric knowledge.
