Stamping part is a method of forming and processing parts (stamping parts) with required shape and dimension by applying external force to sheet, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing), which is called forging. Stamping blanks are mainly hot-rolled and cold-rolled steel sheets and strips.

Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with stiffeners, ribs, undulations or flanges which are difficult to manufacture by other methods to improve their rigidity. Because of the use of precision die, the precision of workpiece can reach micron level, and the repetition accuracy is high, the specifications are consistent, and holes and convex tables can be punched out.

Stamping parts are mainly metal or non-metal sheet, with the help of the pressure of the press, through the stamping die stamping processing, it has the following characteristics:

⑴ Stamping parts are made by stamping on the premise of small material consumption. The parts are light in weight and good in rigidity. After the plastic deformation of the sheet metal, the internal structure of the metal is improved and the strength of the stamping parts is improved.

⑵The stamping parts have higher dimensional accuracy, uniform size and good interchangeability. General assembly and use requirements can be met without further machining.

⑶Stamping parts in the stamping process, because the surface of the material is not damaged, it has a good surface quality, smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.
