Core Viewpoint - The successful trial production of the TXB integrated double door ring, led by Li Auto in collaboration with Yanlong Technology and Mubei, represents a significant technological breakthrough in vehicle body structure design, enhancing safety while achieving lightweight and efficient energy consumption [1][8]. Group 1: TXB Integrated Double Door Ring - The TXB integrated double door ring combines Tailor Welded Blanks (TWB) and Tailor Rolled Blanks (TRB) technologies, allowing for the creation of a single blank from multiple flexible rolled steel plates of varying thicknesses, which are then formed through hot stamping [2][5]. - This innovation is the first in the industry to achieve full coverage of hot-formed non-uniform thickness plates in critical areas (A, B, C pillars), balancing performance and weight effectively [2][6]. Group 2: Technological Advantages - The TXB technology overcomes the limitations of traditional TRB and TWB methods, allowing for precise adjustment of thickness at various positions with fewer components, resulting in a weight reduction of approximately 13%-18% compared to conventional body structures [1][6]. - The design of the TXB integrated double door ring exemplifies a fusion of the advantages of both TWB and TRB, creating a lightweight yet robust structure akin to a "custom suit" for vehicles [5][6]. Group 3: Strategic Collaboration - The successful trial production took place at Yanlong Technology's Suzhou factory, marking a step forward in Li Auto's capabilities in lean body design [8][12]. - Key executives from Li Auto, Yanlong Technology, and Mubei attended the launch ceremony, highlighting the collaborative effort in advancing automotive lightweight solutions [8][10]. Group 4: Industry Impact - The TXB integrated double door ring is expected to redefine industry standards with its superior strength, energy efficiency, and sustainability, contributing to the global automotive industry's lightweight progress [12][14]. - The collaboration aims to address challenges in component structure design, material processing, and precision matching of material thickness and performance, ensuring a safe and green mobility experience for users [14].
