Description

Technical Field

[0002] The stamping process is an efficient and precise metal processing method, which is widely used in many fields such as automobiles, electronics, aerospace, and home appliances. The metal strip is pressed by the stamping die to make it plastically deformed, so as to obtain parts with specific shapes and sizes. In early industrial production, the design and manufacture of stamping dies were relatively simple, and only some parts with relatively simple structures could be produced. However, with the development of industry and the continuous changes in market demand, the precision, complexity and quality requirements of stamping parts are getting higher and higher. In order to meet these needs, the technology of stamping dies is constantly innovating and improving. Modern stamping dies use advanced design concepts and manufacturing processes, such as computer-aided design (CAD), computer-aided manufacturing (CAM), and high-precision processing technologies such as electrical discharge machining and wire cutting. This enables the mold to achieve more complex shapes and more precise dimensions, while improving the service life and production efficiency of the mold. Driven by continuous technological progress and market demand, stamping dies are developing in the direction of high precision, high efficiency, long life and intelligence, making important contributions to the prosperity of the manufacturing industry.
