First of all to understand what is stamping?
     Stamping processing is by means of conventional or special stamping equipment, power, so that the sheet material in the mold directly by the deformation force and deformation, to obtain a certain shape, size and performance of the product parts of the production technology. Sheet metal, mold and equipment are the three elements of stamping. Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing), but also under the material forming engineering technology.
     Stamping used by the mold called stamping die, referred to as die. Dies are special tools for batching materials (metal or nonmetal) into the required pieces. Punching in the stamping is essential, did not meet the requirements of the die, batch stamping production is difficult to carry out; no advanced die, advanced stamping process can not be achieved. Stamping process and mold, stamping equipment and stamping materials constitute the three elements of stamping, only they can be combined to get stamping parts.
     Compared with other methods of machining and plastic processing, stamping has many unique advantages both technically and economically. The main performance is as follows.
(1) stamping processing of high production efficiency, and easy to operate, easy to achieve mechanization and automation. This is because the stamping is to rely on die and stamping equipment to complete the processing, the average number of strokes per stroke up to dozens of times, high-speed pressure to hundreds of times per minute or even thousands of times, and each stroke May get a punch.
(2) stamping due to the mold to ensure that the stamping parts of the size and shape accuracy, and generally do not destroy the surface quality of stamping parts, and mold life is generally longer, so stamping quality and interchangeability, with "exactly the same" Characteristics.
(3) stamping can be processed to a larger size, the shape of the more complex parts, such as small watch to the stopwatch, large to the car longitudinal beam, cover, etc., plus stamping material cold deformation hardening effect, stamping strength and Stiffness are higher.
(4) stamping generally no chip scrap production, less material consumption, and no other heating equipment, which is a kind of material, energy-saving processing methods, stamping parts of the lower cost.
    As the stamping has such superiority, stamping processing in a wide range of applications in various areas of the national economy. For example, in the aerospace, aviation, military, machinery, agricultural machinery, electronics, information, railways, telecommunications, transportation, chemicals, medical equipment, household appliances and light industry and other departments have stamping processing. Not only the whole industry to use it, and everyone directly with the stamping product contact. Like aircraft, trains, cars, tractors, there are many large, medium and small stamping parts. Car body, frame and car ring and other parts are stamping out of the processing. According to the survey statistics, bike, sewing machine, 80% of the watch is stamping parts; TV, tape recorders, 90% of the camera is stamping parts; there are food metal shell
, Steel boilers, enamel pots and stainless steel tableware, all the use of stamping die processing products; even the computer hardware is also the lack of stamping parts.
     However, the stamping process used in the mold is generally dedicated, and sometimes a complex parts need to set a number of molds to shape, and the mold manufacturing of high precision, high technical requirements, is the technology-intensive products. Therefore, only in the stamping parts production of large quantities, the advantages of stamping can be fully reflected, so as to obtain better economic benefits.
    Of course, there are some problems and shortcomings in stamping. Mainly in the stamping process noise and vibration generated by the two kinds of pollution, and the operator's security incidents have occurred. However, these problems are not entirely due to the stamping process and the mold itself, but mainly due to the traditional stamping equipment and backward manual operation caused. With the progress of science and technology, especially the development of computer technology, with the advancement of mechatronics technology, these problems will be improved as soon as possible and be resolved.
