Jiazhan Industrial Ramps Up Efforts in Integrated Die Casting for New Energy Vehicles: Achieving a New Breakthrough in High-Precision CNC Machining of Core Structural Components

As the demands placed on new energy vehicles—specifically regarding body lightweighting and driving range—continue to escalate, "integrated die casting" and "high-precision aluminum alloy structural components" have emerged as the absolute core of the modern automotive supply chain. Aligning itself with these industry trends, Jiazhan Industrial recently successfully completed a comprehensive process upgrade involving the deep integration of its new-generation, large-tonnage, high-precision die-casting units with multi-axis CNC machining centers. To address common industry challenges associated with new energy vehicle structural components—such as uneven wall thickness, complex geometries, and a high susceptibility to internal porosity—Jiazhan Industrial’s technical team utilized FLOW-3D mold flow analysis to optimize its tapered runner system architecture. By combining this design with microsecond-level closed-loop dynamic injection and high-force intensification technologies, the team effectively eliminated the physical conditions that foster the formation of shrinkage cavities and microscopic porosity at the very source. Concurrently, the company introduced multi-axis precision CNC machining centers to lock in micron-level tolerances at critical assembly points, thereby ensuring that the internal dense layer of the components remains completely intact following the machining and cutting processes. Supported by a closed-loop inspection system—featuring high-power 225kV industrial X-ray non-destructive testing equipment and fully automated Coordinate Measuring Machines (CMMs)—Jiazhan Industrial has achieved a full-lifecycle, automotive-grade delivery capability, spanning the entire spectrum from "raw die casting" to "finished, high-precision machining." This capability enables the company to provide global OEMs with safer, more robust, and highly customized solutions for precision components.

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

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.
