This round of industry demand shifts has completely rewritten the product access standards for sheet metal stamping. Previously, traditional sheet metal stamping was mostly used for appliance casings and general computer cases, focusing on meeting basic dimensional standards. However, current energy storage and new energy vehicle operating conditions have stringent requirements. Components such as battery pack heat dissipation brackets, energy storage cabinet reinforcing ribs, and electronic control shielding springs not only require precision tolerances within ±0.05mm but also must meet outdoor salt spray corrosion resistance tests of over 500 hours and vibration fatigue tests of 150,000 cycles. The mass-produced sheet metal stamping parts of this iteration are simultaneously adapted to the requirements of modular resonance digital production. The production end is connected to an industrial data platform, uploading Dynaform sheet springback simulation data, mold wear data, and surface treatment parameters in real time. This enables full-chain data traceability from drawing analysis and process scheduling to finished product inspection, complying with the Ministry of Industry and Information Technology's data compliance management requirements for the manufacturing industry.
In terms of cost and supply chain, benefiting from the 2026 fiscal subsidy policy for equipment upgrades (1.5 percentage points subsidy for fixed asset loans), the production line has completed the domestic replacement of servo stamping equipment. The coverage rate of domestic servo presses and automated deburring equipment has exceeded 72%, resulting in a 24% reduction in overall production costs compared to imported equipment. Meanwhile, in response to the slight price fluctuations of cold-rolled sheet metal in the first half of the year, the product adopts a multi-sheet universal mold design, allowing for the co-production of SPCC galvanized sheet, 5052 aluminum alloy, and 304 stainless steel. This effectively hedges against the risk of rising raw material prices and addresses the potential supply chain disruptions for OEMs. Compared to traditional CNC bending sheet metal, this stamping part maintains a material utilization rate of over 95%, reduces production energy consumption by 18%, complies with the new dual-carbon capacity control regulations for the steel industry, and can provide a complete set of green production traceability reports, meeting the latest EU CSRD supply chain compliance review.
From the current market situation, low-end, extensive sheet metal stamping capacity is being rapidly eliminated, leading to significant industry polarization. Small factories lacking digital inspection and with substandard surface treatment have seen order reductions exceeding 40%, while precision stamping products with fully independent processes and complete compliance qualifications have entered the supply chains of leading domestic energy storage cabinets and new energy charging piles in batches. Currently, this series of sheet metal stamping parts has completed RoHS, REACH, and salt spray fatigue third-party retesting. It also features a localized rapid delivery system, leveraging prefabricated mold technology to reduce the mold-making cycle for non-standard energy storage structural parts to 16 days, a 30% reduction compared to the industry average.
Industry analysts indicate that with the continued implementation of the 15th Five-Year Plan's policy on self-reliance and control over the industrial chain, the sheet metal stamping industry will further concentrate on precision, digitalization, and green technologies. Future product development will focus on overcoming two major pain points: ultra-high strength steel thin-wall stamping and zero-surface-damage forming, further addressing the domestic shortcomings in high-end energy storage components and reducing reliance on foreign suppliers for high-end molds and simulation software.
