The shell of pendant lamp is a stamping part. The stamping part is a method of forming and processing the required shape and size parts (stamping parts) by exerting external force on the plate, strip, pipe and profile by the 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.

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

(1) Stamping parts are manufactured by stamping on the premise of low material consumption. The parts are light in weight and good in stiffness. After plastic deformation of sheet metal, the internal structure of metal is improved and the strength of stamping parts is improved.

(2) The stamping parts have high dimensional accuracy, uniform size with the die, and good interchangeability. General assembly and use requirements can be met without further mechanical processing.

_During the stamping process, because the surface of the material is not destroyed, the stamping parts have better surface quality and smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.
