Compared to fuel vehicles, the demand for stamped sheet metal for pure electric and plug-in hybrid vehicles exhibits two distinct characteristics: First, a large number of new stamped components specifically for battery packs and motor/electronic control housings have been added; second, the use of integrated stamped parts for the vehicle body has increased significantly, with the total weight of sheet metal per vehicle increasing by 12%–20%. Unlike ordinary exterior stamped body panels, new energy vehicle sheet metal places complex requirements on strength, sealing, heat dissipation, and puncture resistance, giving rise to new categories such as multi-layer composite battery guards, topological lightweight crossbeams, and integrated die-cast and stamped brackets, opening up new business tracks for stamping companies.
Changes in industry demand have directly driven adjustments in regional production capacity layout. Traditional sheet metal factories in the Yangtze River Delta and Pearl River Delta regions are accelerating technological upgrades and transformations. In Henan, Sichuan, Hubei, and other major new energy vehicle manufacturing hubs, dozens of new factories specializing in stamping components for new energy vehicles have been established, focusing on three main product categories: high-strength hot stamping, deep-drawn shells, and precision progressive die parts.
Technologically, AI-powered digital stamping has become standard practice for enterprises. Leading manufacturers have implemented AI-based sheet metal layout and online visual inspection systems, increasing material utilization to over 82%. The dimensional accuracy of stamped parts can reach 0.02 mm, significantly improving batch delivery consistency and meeting the stringent automated welding and assembly standards of new energy vehicle manufacturers.
Overall, the automotive stamping sheet metal industry has moved beyond the era of simple scale expansion. The ability to thoroughly understand sheet metal processes specific to new energy vehicles and master the core capabilities of high-strength hot stamping has become crucial for companies to capitalize on market opportunities. Lightweight, integrated, and green precision stamping will remain the industry's unchanging development theme for the next three years
