What Are the Sheet Metal Fabrication and Their Characteristics

Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. It has been widely used in the fields of electronic appliances, communications, automobile industry, medical equipment, etc. For example, in computer cases, mobile phones, MP3, sheet metal is an indispensable component. With the increasing application 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 designed sheet metal can not only meet the requirements of the product's function and appearance, but also make stamping die manufacturing simple and low cost.

Modern Sheet Metal Fabrication technologies include: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending forming, die forging, water jet cutting, precision welding .

The surface treatment of sheet metal parts is also a very important part of the Sheet Metal Fabrication process, because it can prevent parts from rusting and beautify the appearance of the product. The surface pre-treatment of sheet metal parts is mainly to remove oil stains, oxide scale, rust, etc. It prepares for surface post-treatment, and the post-treatment is mainly to spray (bake) paint, spray plastic and rust-proof layer.
