Automotive stamping parts include chassis structural parts, body panels and engine peripheral accessories, manufactured using high-strength steel plates (tensile strength 600-1200MPa) and precision stamping processes. Relying on 1600-ton large closed punch presses and automated feeding systems, complex parts such as door reinforcement plates and shock absorber brackets are formed in one piece, with dimensional tolerance controlled within ±0.1mm. CAE simulation is used to optimize stamping paths during production to reduce springback. Key parts undergo 720-hour salt spray testing without rust. Supplying multiple joint-venture automakers, chassis stamping parts for a certain model passed 300,000km road test verification with 100% fatigue strength compliance, with annual supply exceeding 2 million pieces.
