Shenzhen Precision Hardware Stamping Parts Processing - Main Features of Stamping Parts
08-21 / 2019

Stamped parts are mainly formed by stamping metal or non-metallic sheets with the pressure of a press and forming them through stamping molds. They mainly have the following characteristics:


Stamped parts are manufactured by stamping with minimal material consumption. Their parts are lightweight and have good stiffness. After plastic deformation of the sheet metal, the internal structure of the metal is improved, resulting in an increase in the strength of the stamped parts.


⑵ Stamped parts have high dimensional accuracy, uniform and consistent dimensions with the same module, and good interchangeability. No further mechanical processing is required to meet general assembly and usage requirements.


During the stamping process, stamped parts have good surface quality and a smooth and beautiful appearance due to their undamaged surface, which provides convenient conditions for surface painting, electroplating, phosphating, and other surface treatments.
