Understand the test of stamping die

Most of the working conditions of dies are very bad. Some of them often suffer from large impact loads, resulting in brittle fracture. In order to prevent the die parts from breaking suddenly at work, the mold should have higher strength and toughness. From the view of the industry structure, the rapid development of private enterprises, the increase of the vitality of the state-owned enterprises, the rapid increase in the number and ability of the professional mould manufacturers facing the market, the development of the production Park of stamping parts processing mould adapted to the production characteristics of the mould industry, and the great progress in the underdevelopment areas of the central and Western mould industries.


There are many kinds of classification methods for dies. They are used for stamping dies, forging dies, casting moulds and plastic moulds. Welding is not called mold, welding only fixture, such as for cold bending or hot bending, or positioning, are called fixtures. I am talking about written language. As for common saying, maybe some places will call jig called mold.


The stamping dies of Dalian are processed into parts (or semi-finished products) in cold stamping. Stamping is a pressure processing method for the required parts at room temperature, using the mold installed on the press to exert pressure on the material to produce the separation or plastic deformation.


The domestic stamping die industry is constantly catching up with the world's advanced level and narrowing the technical gap with the developed countries. Many domestic precision stamping dies have been able to compete with the imported products in the main performance, and the overall level of the industry has been significantly improved, not only to realize the import substitution, but also to export to the United States and Japan. The developed countries and regions of the industry.
