Sheet metal definition

Until now there has not been a relatively complete definition of sheet metal. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold working process for metal sheets, including shearing, punching /cutting/compositing, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its distinctive feature is that the thickness of the same part is consistent.


Generally speaking, the basic equipment of a factory includes shears, CNC punches/lasers, plasma, water jet cutting machines/composite machines, bending machines and various auxiliary equipment such as: decoilers, leveling machines, deburring machines, point Welding machine etc.

The meaning of sheet metal

The word sheet metal comes from the English platemetal. Generally, some metal sheets are plastically deformed by hand or die stamping to form the desired shape and size. More complex parts can be further formed through welding or a small amount of mechanical processing, such as Chimneys, stoves, and car casings commonly used in households are all parts.


Sheet metal processing is called processing. Specifically, for example, plates are used to make chimneys, iron barrels, fuel tanks, ventilation ducts, elbows, garden spaces, funnel shapes, etc. The main processes are shearing, bending and buckling, bending, welding, riveting, etc., which require Certain knowledge of geometry.


Sheet metal parts are thin plate hardware, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is – parts whose thickness does not change during processing. The corresponding ones are castings and forgings. , machined parts, etc. For example, the outer iron shell of a car is a part, and some cabinets made of stainless steel are also parts.
