Dongfeng Integrated Die-Cast Rear Floor Advances DH3

Dongfeng Integrated Die-Cast Rear Floor DH3

Dongfeng integrated die-cast rear floor DH3 production has reached an important project milestone, with Dongfeng Electronic Technology Co., Ltd. (DETC) completing the first rear-floor component at its Wuhan Branch. The project brings together teams from Dongfeng Electronic Technology Co Ltd, Dongfeng Motor Group Co., Ltd. Yipai Automotive Technology Company, Dongfeng Motor Corporation R&D Institute, and Huawei Technologies Co Ltd. The component is being developed for the DH3 and future models, while the participating organizations continue advancing integrated die-casting applications across vehicle programs.

Production Capacity and Project Progress

The project is currently in the ET0 phase, and the first trial-production run achieved an overall yield rate above its target. Project milestones are also reported to be progressing according to plan. DETC will manufacture the rear floor using a 10,000-ton die-casting cell, with planned annual production capacity reaching 120,000 units. This production arrangement is intended to support the DH3 as well as subsequent models, establishing the die-casting program as part of DETC’s broader manufacturing activity for future vehicle applications.

Integrated Die-Casting Process

The rear-floor project covers four main manufacturing processes: die casting, post-processing, machining, and joining. Post-processing has been automated, while DETC developed the machining center internally for the project. The combination of these processes is designed to integrate multiple production stages within the component manufacturing workflow. The companies involved will continue working on the broader adoption of integrated die-casting technology for models developed by Dongfeng Yipai Technology and Yijing-branded models, extending the technology beyond the initial DH3 application as development programs progress.

Project Collaboration

The program involves cooperation among several organizations within the broader Dongfeng development and manufacturing ecosystem, alongside Huawei Technologies Co Ltd. DETC is responsible for the die-casting production activity at its Wuhan Branch, while Dongfeng Motor Corporation R&D Institute and Dongfeng Yipai Technology are involved in the vehicle-development side of the project. The collaboration also provides a framework for applying integrated die-casting technology to additional vehicle programs, including future models associated with Dongfeng Yipai Technology and Yijing-branded vehicles.

Industry Impact & Outlook

The project demonstrates a continued move toward integrating major vehicle-component manufacturing processes around large-scale die-casting equipment, while automation and internally developed machining capabilities are being incorporated into the production workflow. For Dongfeng Electronic Technology Co Ltd, the planned 120,000-unit annual capacity creates a production base for the DH3 and subsequent models. The next relevant milestones are continued ET0 development, production validation, and expansion of integrated die-casting applications across additional Dongfeng Yipai Technology and Yijing-branded vehicle programs.
