What is the representative of the progressive die of the connector of the connecting device

The progressive dies for connecting devices represented by precision and complexity, including dies for connectors, brushes, electrical terminals and springs, have complex structures, difficult design and manufacture, and high precision requirements. Its products are characterized by small size, many curved surfaces, complex shapes and high precision. In recent years, with the market requirements and the improvement of the mold level, there are more and more high-precision micro-products, thus pushing the mold level to a new level. For example, the high-precision micro-connected device progressive die manufactured by Jiangsu Huafu Electronics Co., Ltd. can reach a punching speed of more than 2500 punches/min on a high-speed punching machine, and the die life is close to the international advanced level of similar molds. The 0.4mm pitch high-precision miniature connector progressive die newly developed by a company has a manufacturing accuracy of 0.5μm and a minimum punch size of only 0.13mm. The direct grinding process is used to achieve the mirror surface, which ensures that the minimum pin of the product is 0.17mm. And S-shaped bending accuracy is within 0.01mm and other high-precision requirements. Its high-speed mass production mold performance and mold life are close to the international advanced level of similar molds. The electrical terminal progressive die manufactured by a certain company realizes the forming, thinning and 90° twisting of 8 small-spacing connection points of the product, and the die life is more than 200 million strokes. The overall level of the mold is comparable to that of similar international molds.
