What Is Metal Stamping Processing?

Stamping process is a metal processing method. It is based on the plastic deformation of metal. It uses dies and stamping equipment to apply pressure to the sheet metal to cause plastic deformation or separation of the sheet metal, thus obtaining parts (stamping parts) with certain shape, size and performance. Stamping can be divided into four basic processes:

Blanking: A stamping process (including punching, blanking, trimming, cutting, etc.) that separates sheet metal.

Bending: A stamping process in which a sheet is bent into a certain angle and shape along a bending line.

Drawing: A stamping process in which flat sheets are turned into various open hollow parts or the shape and size of hollow parts are further changed.

Fine blanking: For products with high punching precision, for products with high size and surface light volume requirements, the fine blanking die is used to meet the drawing requirements.

Local forming: A stamping process (including flanging, bulging, leveling and shaping processes, etc.) that uses local deformations of various properties to change the shape of blank or stamping parts.
