As China's economy continues to develop forward by leaps and bounds, the mold industry does as a key area, which is one of the basic industries in China. New technology occurs, and social production also attaches importance to norms and standards, and the mold industry plays an extremely significant role in the scale production of modern industry. Mold is an important symbol to consider the manufacturing levellow volume plastic manufacturing of a country, mold can bring great economic benefits, mold processing goods are often several times the value of the mold. Because the selection of mold to carry out the production of goods with excellent quality, efficient production, saving resources, low application costs, simple operation, suitable for mass production and other advantages, especially stamping technology to be in the automotive industry, machinery production, instrumentation, light industry, household appliances, communications technology, national defense and aerospace and other fields of product production has won a more common application. It can be said that mold processing is essential, the general trend of China's mold market is the rapid development of production and sales, and now the total annual production in China has long been located in the world's third. And the rapid development of computer manufacturing assistance system, to our country also brought great opportunities, our country introduced this system, generally used in the mold industry, and achieved promising results. Computer-aided design and manufacturing is not only a big change, but also a strategy for the future development of the mold industry.

Stamping is the use of the die to increase the pressure of the plate or increase a certain amount of tension, so as to promote the plate plastic deformation, or shear force on the plate so that the plate separation process. The raw materials used for stamping are generally sheet metal, thin profiles, thin-walled tubes, etc., and are generally processed at room temperature, when the material is cold, thus also known as cold stamping. In order to meet the requirements of dimensional error, roughness, shape, production lot size, raw material characteristics, etc. of the stamped parts, the stamping process can be said to be in various ways. However, in general, it can be divided into two categories: separation process and forming process, which is also the common classification method. The separation process is generally divided into punching, cutting, and dropping. In other words, in the case of stamping, the plate and the stamped part are separated along a certain contour to obtain the part. The forming process generally includes deep drawing, bending, expansion, hole-flipping, reverse-edge process, etc. The forming process is to make the stamping blank under the normal deformation standards of plastic deformation, and can be converted into the necessary shape of the parts.

Compared with other processing methods, stamping has the following characteristics in economic and technical aspects (1) Reduction of material consumption, control of production costs, and reduction of specific production costs. Production using molds is fast, efficient and accurate. It is possible to obtain goods that cannot be processed in general and produce economical and durable products. (2) The dimensional accuracy of stamped parts is ensured by the die base or the cavity cutter, which allows the manufacture of complex shaped parts and the complexity of the products, and the stamping also has the characteristics of stable quality and good exchangeability. (3) Stamping is also called cold stamping because it is processed in cold conditions and does not require a tool to carry out a lot of cutting of metal materials, so it not only achieves energy saving, but also saves materials and costs. (4) General press processing large products per minute can have the efficiency of processing dozens of parts, high-speed press processing small products is able to process hundreds of parts per minute, large advanced factories to achieve robot unmanned production, so it is automated and mechanized, so this is a very efficient production and processing methods. However, mold processing also has its limitations, mold design is complicated, and the price of the mold is high, for small batch production is not economical.

In today's not different forming processing methods between the liaison has been strengthened, plate stamping is a basic common processing method of metal plastic processing, stamping forming process also has its own new development, in recent years, with the rapid development of science and technology, mold design and manufacturing has a new idea, mold manufacturing is a long progress. Now China's mold processing field m30s whatsminerbrings the output value has exceeded the output value of the machine tool industry. The related stamping technology aspects are causing more and more concern to everyone. The corresponding research and discussion on the theoretical problems and design status of stamping process also advance with the continuous development. The design and processing of dies to improve the quality and accuracy of the stamped parts and to increase the service life of the dies have become a problem of concern to everyone.

The stamping process is efficient compared to other processing methods, and can produce several pieces per minute for large products, and more than a few thousand pieces for small products at high speed. The tooling is efficient, exchangeable, and saves raw materials, and it has been widely used because it is equipped with robots to achieve intelligent production.
