Automotive shock absorber stamped parts are core components manufactured via the stamping process and fall under the category of automotive parts. These components-which include spring trays, spring seats, spring brackets, end caps, sealing covers, compression valve covers, oil seal seats, and dust covers-are shaped through plastic deformation to achieve specific structural designs and dimensions. They serve the functions of structural support and vibration damping within the vehicle.
Production involves processes such as cold and hot stamping, utilizing presses and dies to shape materials like steel and aluminum alloys; these parts are characterized by complex geometries and high precision requirements. The industry is actively adopting high-strength steel and lightweight materials. "Made in China 2025" identifies lightweighting as a core development direction for the automotive industry, with a target to reduce vehicle weight by 35% by 2030 compared to 2015 levels. Achieving this requires advanced manufacturing technologies such as internal high-pressure forming and hot stamping of ultra-high-strength steel. Industry growth is driven by demand in the new energy vehicle (NEV) market, where the need for lightweighting is particularly urgent. In 2022, domestic demand for metal stamped parts for passenger vehicles reached 35.75 billion units, and NEVs are projected to account for 25% of total vehicle sales by 2025. Government bodies, including the State Council, have issued policies to regulate and ensure the healthy development of the auto parts industry.
