Introduction to Stamped Parts

Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the desired shape and size. Stamping and forging both belong to plastic processing (or pressure processing), collectively known as forging and pressing.

Stamping is a production technology that uses the power of conventional or specialized stamping equipment to directly subject sheet metal to deformation forces within a die, thereby obtaining product parts with specific shapes, dimensions, and properties. Sheet metal, dies, and equipment are the three essential elements of stamping. Based on the stamping temperature, it is divided into hot stamping and cold stamping. The former is suitable for processing sheet metal with high deformation resistance and poor plasticity; the latter is performed at room temperature and is a commonly used stamping method for thin sheets. It is one of the main methods of metal plastic processing (or pressure processing) and also belongs to materials forming engineering technology.

The dies used in stamping are called stamping dies, or simply stamping dies. A stamping die is a specialized tool used to process materials (metal or non-metal) in batches into the desired stamped parts. Dies are crucial in stamping; without suitable dies, mass production is difficult, and without advanced dies, advanced stamping processes cannot be achieved. Stamping processes, along with dies, stamping equipment, and stamping materials, constitute the three essential elements of stamping; only when these elements are combined can stamped parts be produced.
