Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

1.Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the steel in the world is sheet material, most of which is stamped into finished products. The body, chassis, fuel tank, radiator fins of automobiles, the steam drum of boilers, the shell of containers, the iron core silicon steel sheets of motors and electrical appliances are all stamped. There are also a large number of stamped parts in products such as instruments and meters, household appliances, bicycles, office machinery, and daily utensils.

2.Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die and deform it, thereby obtaining product parts with certain shapes, sizes and performances. Sheet metal, die and equipment are the three elements of stamping. According to the stamping temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure processing) and also belongs to material forming engineering technology.

3.The die used for stamping is called a stamping die, or simply a die. A stamping die is a special tool for batch processing materials (metal or non-metal) into the required stamping parts. The die is crucial in stamping. Without a die that meets the requirements, batch stamping production will be difficult to carry out; without advanced dies, advanced stamping technology cannot be achieved. The stamping process, die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only when they are combined with each other can stamping parts be obtained.


Sheet metal, die and stamping equipment are the three essential elements of stamping processing.
Characteristics and application of stamping processing Stamping production relies on dies and presses to complete the processing process. Compared with other processing methods, it has the following characteristics in terms of technology and economy:
(1) The dimensional accuracy of stamped parts is guaranteed by the die, and they have exactly the same characteristics, so the quality is stable and the interchangeability is good.
(2) Due to the use of die processing, parts with thin walls, light weight, good rigidity, high surface quality and complex shapes that cannot be or are difficult to manufacture by other processing methods can be obtained.
(3) Stamping processing generally does not require heating of the blank, nor does it require large amounts of metal cutting like cutting processing, so it is not only energy-saving, but also metal-saving.
(4) For ordinary presses, dozens of pieces can be produced per minute, while high-speed presses can produce hundreds or thousands of pieces per minute. Therefore, it is a highly efficient processing method.
Due to the above-mentioned outstanding characteristics of stamping technology, it is widely used in various fields of the national economy. For example, industries such as aerospace, machinery, electronic information, transportation, weapons, daily electrical appliances and light industry all have stamping processing. Not only is it widely used in the industry, but everyone comes into direct contact with stamping products every day. Stamping can produce small precision parts in watches and instruments, as well as large covers for cars and tractors. Stamping materials can use ferrous metals, non-ferrous metals and some non-metallic materials.
