Three-party collaboration forges future: Yizumi, Yujiang Die Casting, and Shanghai Jiao Tong University Join Hands to Drive New Breakthroughs in Aluminum-Magnesium Alloy Forming Technology

Amidst the global trend of manufacturing transforming towards lightweighting, high performance, and green practices, the innovation of aluminum and magnesium alloy forming technology has become crucial for driving industrial upgrading. On January 30th, YIZUMI, Shanghai Jiao Tong University, and Chongqing Yujiang Die Casting Co., Ltd. (hereinafter referred to as "Yujiang Die Casting") simultaneously advanced on both technical research and industrial application fronts. They demonstrated the effectiveness of collaborative innovation between industry, academia, and research through the mid-term acceptance of two significant projects, jointly injecting new momentum into the high-quality development of the aluminum and magnesium alloy forming industry.

Since July 2024, Haitian International has partnered with the National Engineering Research Center for Precision Forming of Light Alloys at Shanghai Jiao Tong University, focusing on the research and development of semi-solid injection molding technology for magnesium alloys. Leveraging the research strengths of the National Engineering Research Center for Precision Forming of Light Alloys at Shanghai Jiao Tong University and Haitian International's deep expertise in equipment development and process integration, the project has achieved phased results in material development, process simulation, and equipment innovation.

On January 30th, the mid-term acceptance meeting for the collaborative project was successfully held. The meeting focused on in-depth discussions concerning key topics such as the research and development progress of the "Semi-Solid Magnesium Alloy Key Components and Forming Process Collaborative Project," material adaptability test data, and process window expansion. The project team conducted systematic research on the process advantages of semi-solid injection molding technology in reducing shrinkage cavities and improving material density, and validated the feasibility of the solution through systematic testing.

The achievement of phased goals has laid a solid foundation for subsequent prototype manufacturing and large-scale process validation. Next, both parties will focus on promoting intelligent control of the forming process, online defect monitoring, and global collaborative optimization of process-material-equipment, accelerating the transition of technology from laboratory to industrialization.

Subsequently, the collaborative project between Shanghai Jiao Tong University and Yujiang Die Casting successfully passed its mid-term review. This review focused on the transformation path of technical achievements towards large-scale production scenarios. Both parties conducted in-depth and pragmatic exchanges surrounding key issues such as process window optimization, quality consistency control, and comprehensive cost management in the mass production process.

As a key player in the die-casting industry, Yujiang Die Casting, relying on its solid industrial foundation and keen understanding of market trends, has provided valuable practical feedback for the engineering refinement of cutting-edge technologies. This demand-oriented collaborative model has effectively promoted the deep integration of technology research and development directions with actual industrial application scenarios.

It is worth mentioning that the core technological achievements jointly tackled by Yizumi and Shanghai Jiao Tong University will be applied to the multiple sets of large-scale magnesium alloy semi-solid injection molding production lines that Yujiang Die Casting is about to introduce. This substantive collaboration marks the complete innovation chain from "basic research – equipment innovation – process development – industrial application" being seamlessly connected.

Consequently, the closed-loop system jointly built by the three parties is systematically bridging the critical gap from laboratory to large-scale production for semi-solid injection molding technology of aluminum-magnesium alloys. This innovation model, driven by industry chain demands, not only significantly accelerates the technological maturity process but also ensures that innovative achievements can be efficiently transformed into actual productivity, injecting continuous momentum into industrial upgrading.

Currently, aluminum-magnesium alloy forming technology directly impacts the development level of strategic industries such as new energy vehicles, aerospace, and high-end electronics. In this context, Yizumi, Shanghai Jiao Tong University, and Yujiang Die Casting have formed a closely collaborative and continuously innovative organic partnership.

• Yizumi and Shanghai Jiao Tong University are committed to breakthroughs in cutting-edge technologies and equipment.

• Shanghai Jiao Tong University and Yujiang Die Casting focus on the R&D and technological industrialization of new materials and new products.

• Yizumi and Yujiang Die Casting, on the other hand, realize the ultimate release of technical value through equipment supply and process support.

This collaborative model, driven by industrial chain demands and aimed at technology implementation, not only accelerates the process of technological innovation but also builds a demonstration case of deep integration of "industry, academia, research, and application" for the industry.

The successful completion of these two mid-term reviews marks an important milestone in the continuous deep cultivation of the three parties in the field of aluminum-magnesium alloy forming. In the future, the parties will further deepen their interaction in areas such as improving process robustness, expanding applications for complex structures, and jointly building industry standards, to collectively foster an open, collaborative, and continuously innovative lightweight industry ecosystem.
