On December 4, Hubei Daily carried a report stating that on December 2, at the 2025 Yangtze River Industrial Technology Innovation Conference, Hubei Hangte Equipment Manufacturing Co., Ltd. introduced the world's inaugural integrated low-pressure cast all-aluminum load-bearing large frame. This groundbreaking technology breaks through the processing constraints associated with ultra-large thin-walled structural components, enabling, for the very first time, the production of an integrated all-aluminum frame with a projected surface area of 4.2 square meters and wall thicknesses spanning from 4 to 50 millimeters.

Traditionally, all-aluminum frames are constructed by assembling numerous individual parts, a process that is not only intricate but also costly. Moreover, the connection points in these assemblies often represent vulnerabilities in terms of structural rigidity and safety. In contrast, Hangte Equipment's innovation streamlines the frame design into a single, integrated casting. This approach minimizes the number of weak connection points, thereby enhancing the overall structural stability and safety of the frame.

The manufacturing process is meticulously monitored in real-time through an intelligent control system. This system ensures a steady and precise injection of aluminum alloy liquid into an extra-large mold cavity under a carefully regulated low-pressure environment. The result is a flawless filling and uniform solidification of the metal, even in ultra-thin wall sections. Following optimization of the material formulation, the molded frame boasts a combination of high strength, excellent toughness, and robust fatigue resistance.

Currently, this cutting-edge technology has been implemented in the BYD Yangwang U8L Dingshi Edition. Industry specialists are of the opinion that this achievement signifies China's ascension to a global leadership position in the manufacturing of large and complex aluminum alloy structural parts. It is anticipated to spearhead a technological revolution in the design and production of large frames for new energy vehicles.
