Precision Stamping Process Upgraded: Jiazhan Industrial Introduces High-Precision Multi-Station Progressive Dies to Enhance Precision Manufacturing Capabilities for Automotive Stamped Parts

Summary: In the manufacturing of modern automotive metal components, the stamping process maintains an irreplaceable position due to its high efficiency, exceptional stability, and superior capability in forming complex, high-strength structural parts. To further expand the production frontiers for precision hardware and automotive body accessories, Jiazhan Industrial recently undertook a comprehensive technical capacity expansion and process upgrade of its precision stamping production lines. This technical upgrade focused on introducing industry-leading multi-station progressive die technology and large-tonnage, high-precision stamping equipment, thereby achieving a fully automated, closed-loop production cycle—spanning from automatic coil feeding and multi-station continuous stamping to precision blanking and final product forming. Through microscopic stress analysis of stamping die structures, Jiazhan Industrial successfully resolved technical challenges—such as cracking, springback, and excessive burring—that frequently arise during the high-speed stamping of high-strength steel and thick aluminum alloy sheets; consequently, critical geometric and positional tolerances are now strictly controlled within the extremely narrow tolerance bands required for automotive-grade components. This initiative has not only boosted the overall production efficiency of the stamping lines by over 35% but also provided a robust technical foundation for the large-scale, high-volume fulfillment of orders for automotive seat frames, roof rack connectors, and precision chassis hardware. This capability perfectly satisfies the stringent quality control requirements of OEMs regarding high-limit performance and high-frequency delivery schedules.
