A 'pull' Formed Energy Guardian: The Hardcore Upgrade Path For Aluminum Deep Drawing Shells
Jul 08, 2025
The aluminum deep-drawing stamping battery case, made of aluminum, achieves integrated forming through deep-drawing stamping technology, breaking the limitations of ordinary cases' splicing and assembly. Like armor, it strengthens battery protection. With its seamless structure, it enhances sealing performance and impact resistance. Its lightweight nature also features efficient heat dissipation. Compared with traditional processes, it reduces material waste and shortens processing procedures, achieving a dual breakthrough in the safety and durability of new energy batteries. It is not only a product of technological innovation but also a tough choice for guarding energy safety.
material properties
1.The aluminum deep-drawing stamping battery case, crafted from high-purity aluminum alloy, combines light weight with high strength. With a density of only about 2.7g/cm³, it is over 40% lighter than a steel case of the same volume, yet can withstand severe impacts, providing stable protection for the core components of the battery.
2.The material has excellent ductility, which is suitable for the deep-drawing process of the aluminum deep-drawn stamped battery enclosure. It can be formed into complex curved structures in one go, avoiding splicing gaps. Meanwhile, it has good thermal conductivity, helping the battery dissipate heat efficiently and maintain stable operation.
3.The aluminum alloy material endows the deep-drawn aluminum stamping battery shell with excellent corrosion resistance and recyclability. It can resist erosion from humid, acid, alkali and other environments, with a recycling rate of over 90% after scrapping, which conforms to the concept of environmental protection and recycling in the new energy industry.
production process
1.Raw material preparation: Select high-purity aluminum alloy coils, cut and clean them to remove impurities, then optimize material toughness through annealing treatment, providing a suitable base material for the integrated forming of the deep-drawn aluminum stamping battery shell.
2.Integrated forming: Use custom molds to perform continuous deep-drawing stamping on the sheet, completing the shaping of the cavity structure in a single process, enabling the aluminum battery case made via deep-drawing stamping to achieve seamless integration and eliminating the splicing step.
3.Precision processing: Trim the formed shell and perform surface oxidation to improve dimensional accuracy and corrosion resistance. After passing the final inspection, the aluminum deep-drawing stamping battery case is completed.
