Stamping die into the golden age of development

In recent years, the level of stamping die in our country has been greatly improved. Large stamping die has been able to produce a single set of weight of more than 50 tons of mold. And has been able to produce mid-range car supporting panels mold. Domestic stamping die industry is constantly catching up with the world's advanced level, and constantly narrowing the gap between developed countries and technology, many domestic precision stamping die in the main performance has been able to compare with imported products.

However, China's exports in most of stamping die is a low technology content in the low-end products, so the upscale mold market with high technical content to meet the overall satisfaction rate was lower than that of the stamping die, the die development has been lagging in stamping production, and in some low grade Jane Dan Chongmo, has tended to pile up in excess of requirement of fierce market competition.

The material used in Dalian stamping die is cold working die steel. It is a die steel with large amount of application, wide application and various kinds. The main performance requirements are strength, toughness and wear resistance. The development trend of cold die steel in high alloy steel D2 (equivalent to our performance on the basis of Cr12MoV), divided into two branches: one is to reduce the amount of carbon and alloy elements, improve the distribution uniformity of carbides in steel, improve the toughness of the mold.

Stamping die is a high quality, high efficiency product tool. The stamping process has the advantages of high production efficiency, convenient operation, and easy realization of mechanization and automation. Therefore, stamping dies also play an important role in the manufacturing process. As a big manufacturing country in China, the stamping die market is expanding and has a good potential for development.

Stamping die work to withstand shock, vibration, friction, pressure and tension, bending and torsion load, and even work at higher temperatures (such as cold extrusion), complex working conditions, easy abrasion, fatigue, fracture and deformation phenomenon. As a result, the material requirements for the die work parts are higher than those of the ordinary parts.
