Aluminum Alloy Prismatic Battery Casing

Our aluminum alloy prismatic battery casing is a high-performance product designed to meet the needs of modern battery systems, aiming to provide reliable protection and excellent performance for applications such as electric vehicles, energy storage systems and portable electronic devices.

Lightweight design: The application of aluminum alloy material enables our shell to significantly reduce weight while ensuring strength. This not only improves the energy efficiency of electric vehicles, extends the battery life of portable devices, but also reduces transportation and installation costs.

Heat dissipation performance: The high thermal conductivity of aluminum alloy ensures that the battery can quickly dissipate heat during operation, avoid overheating, and ensure that the battery is safe and stable when working under high load. The improvement of heat dissipation performance directly extends the service life of the battery and improves the safety of the overall system.

Corrosion resistance: The aluminum shell treated with anodizing and special coating has strong corrosion resistance, can be used for a long time in various harsh environments, prevents external factors from corroding the battery, and ensures the stable performance of the battery.

High strength and reliability: The aluminum alloy battery case is not only lightweight, but also has extremely high strength and durability. It can withstand various external shocks and vibrations and provide solid protection. This makes our products stable and safe during transportation, installation and use.

Environmental compliance: Our production process strictly follows environmental standards, and the materials used are non-toxic and harmless and environmentally friendly. We are committed to providing green products and reducing the burden on the earth.

Raw material preparation: Material selection and cutting: Select high-quality aluminum alloy sheets and cut them into billets of the required size according to the design specifications.
Continuous stamping: Use a continuous stamping machine to perform multi-station stamping on the aluminum sheet. The aluminum sheet is gradually formed through multiple mold stations during the stamping process to ensure the precise shape and size of the shell.
Deep drawing and trimming: The outline of the shell is further formed through the deep drawing process, and excess material is removed at the trimming station to ensure smooth and neat edges.
Surface cleaning: The cut aluminum sheet is cleaned to remove oil, dust and other impurities to ensure the smooth progress of subsequent processing.
Finishing process: Including deburring, grinding, polishing, etc., to ensure that the surface of the shell is smooth and the edges have no sharp corners.
Dimension and appearance inspection: Use measuring tools to accurately measure the size of the shell to ensure that it meets the design specifications. Check whether there are scratches, bumps and other defects on the surface of the shell.
Packaging: After cleaning the qualified shell, package it according to standard packaging requirements to prevent damage during transportation.
Logistics arrangement: Arrange transportation according to customer needs and deliver the products to the customer's designated location in a timely manner.

1. Mechanical Strength Test

• Impact Test: Place the shell on a specific device to simulate the impact conditions in actual use and evaluate its impact resistance.
• Compression Test: Apply a certain pressure to the shell to test its compressive strength to ensure that it will not be deformed or broken by external forces in actual use.

2. Corrosion Resistance Test

• Salt Spray Test: Place the shell in a salt spray test chamber to simulate the corrosion conditions in marine climate or industrial environment and test the corrosion resistance of the shell.
• Chemical Reagent Test: Treat the shell surface with specific chemical reagents (such as acid and alkali) to evaluate its corrosion resistance in different chemical environments.

3. Thermal Cycle Test

• High and Low Temperature Cycle Test: Alternately cycle the shell in high and low temperature environments to test the performance and stability of its materials under extreme temperature changes.

4. Thermal Conductivity Test

• Thermal Conductivity Determination: Measure the thermal conductivity of the shell material through professional equipment to ensure that it has good thermal conductivity and can effectively dissipate heat.

5. Sealing Test

• Airtightness Test: Apply a certain pressure of gas in the shell to check whether there is gas leakage to ensure the sealing performance of the shell.
• Watertightness test: Immerse the shell in water, apply pressure on the inside, check whether water enters, and ensure its waterproof performance.

6. Dimension and appearance inspection

• Precision measurement: Use precision measuring tools (such as three-coordinate measuring machine) to measure the various dimensions of the shell to ensure that it meets the design specifications.
• Appearance inspection: Visual inspection and use surface inspection equipment to check whether there are scratches, bumps, discoloration and other defects on the surface of the shell to ensure the appearance quality.

7. Assembly test

• Trial assembly: Trial assembly of the shell with the battery module and other related components to check its compatibility and fit with other components.
