Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and large-scale mass production performance. It is widely used in electronics, communications, automotive, medical equipment, etc., for example. In computer cases, mobile phones, and MP3s, sheet metal is an essential part.

With the increasing use of sheet metal, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must be proficient in the design skills of sheet metal parts, so that the design of sheet metal meets the product. The functions and appearance requirements make the stamping die simple to manufacture and low in cost.

Sheet metal is sometimes used as a gold plate. The word comes from the English platemetal. Generally, some metal sheets are plastically deformed by hand or die to form the desired shape and size, and can be further welded or a small amount of machining. The formation of more complex parts, such as the chimneys commonly used in the home, the iron stove, and the car shell are all sheet metal parts.

Sheet metal processing is called sheet metal processing. Specifically, the use of sheet metal to make chimneys, iron drums, oil tanks, ventilation pipes, elbows, rounds, rounds, funnels, etc. The main processes are shearing, bending, bending, bending, welding, riveting, etc. Certain geometric knowledge.

Sheet metal parts are thin-plate hardware, that is, parts that can be processed by means of stamping, bending, stretching, etc. A general definition is a part with constant thickness during processing. Corresponding to casting parts, forging parts, Machined parts, etc., for example, the outer iron shell of the car is a sheet metal part, and some of the stainless steel cabinets are also sheet metal parts.

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

The surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, because it has the effect of preventing the parts from rusting and beautifying the appearance of the product. The surface pretreatment of sheet metal parts is mainly to remove oil, scale, rust, etc., which prepares for surface post-treatment, and the post-treatment is mainly spray (baked) paint, spray and rust-proof layer.
