Electric Vehicle Lithium Battery Pack Casing

A3003-H14 is a common aluminum alloy material with good processability, corrosion resistance, weldability, and easy surface treatment. It is suitable for applications in a variety of fields and is the first choice for making battery casings. It is precisely because of these excellent properties of aluminum that the battery casing can provide safe and reliable protection for the vehicle battery system.

• Heat dissipation and insulation: Aluminum has good thermal conductivity and can effectively conduct and dissipate the heat generated by the battery, maintain the temperature stability of the battery components, and improve its working efficiency and lifespan. At the same time, the aluminum casing can also play a certain role in thermal insulation to prevent excessive cooling of battery components in low-temperature environments.

• Design flexibility: Aluminum has good processing properties and is easy to form, cut and weld. It can realize the design of complex shapes and structures to meet the needs of different models and battery components.

• Environmentally friendly and sustainable: Since aluminum is a recyclable metal material, the production and use of aluminum battery casings has less impact on the environment and meets the requirements of sustainable development.

• Beautiful appearance: Aluminum has good surface treatment properties and can be anodized, sprayed, electroplated and other surface treatments, giving the electric vehicle lithium battery pack casing a beautiful appearance and texture.

• Advanced equipment and processes: The company has advanced production equipment and processes, which can achieve efficient and precise continuous stamping processing to ensure product quality and production efficiency.

• Supply of high-quality raw materials: The company has established long-term and stable cooperative relationships with high-quality aluminum material suppliers, able to provide high-quality and reliable raw materials to ensure product quality and performance.

• Customized services: The company can provide personalized customized services based on customer needs and requirements, including product design, surface treatment, packaging, etc., to meet the needs of different customers.

• Cost advantage: The company has an excellent production management team and efficient production processes, which can reduce production costs and improve product competitiveness and market share.

• Good customer reputation and reputation: The company adheres to the concept of honest management, wins the trust and praise of customers with high-quality products and services, and establishes a good brand image and reputation.

Material preparation: First prepare the aluminum plate material, usually using aluminum plates pre-cut to appropriate sizes as raw materials. The selection of aluminum plates should take into account the design requirements of the enclosure and the specifications of the final product.

1. Feeding: The aluminum plate is fed into the feeding system of the continuous stamping machine, usually by coil feeding, that is, the aluminum plate is pulled out of the reel and transferred to the working area of the stamping machine.

2. Continuous stamping: Aluminum sheets are continuously stamped on a continuous stamping machine. The working principle is that through the continuous movement of the upper and lower molds, the aluminum plate is punched, formed, and bent in sequence to gradually complete the shape and structure of the shell.

3. Cutting and finished product processing: After stamping is completed, the aluminum plate is cut into individual shell parts by a cutting machine or slitter. The finished product is then subjected to surface treatments such as deburring, decontamination, and polishing to improve appearance quality.

4. Cleaning and drying: The processed finished product is subjected to ultrasonic cleaning to remove oil stains on the surface of the finished product and further completes the drying process.

5. Quality inspection: Conduct quality inspection on finished products, including appearance inspection, dimensional measurement, strength testing, etc., to ensure that the product meets design requirements and standards.

6. Packaging and transportation: Finally, the finished product is packaged, using appropriate packaging materials and methods to ensure that the product is not damaged during transportation. The finished product is then boxed and shipped to downstream customers or production lines.

The packaging and transportation conditions of Electric vehicle lithium battery pack casing need to meet the requirements of protecting product safety, reducing damage and facilitating transportation. We use suitable packaging materials to protect aluminum battery casings from damage such as crushing, impact and vibration. Mark the product name, specifications, quantity, weight and other information on the packaging box, and attach easy-to-recognize labels and shipping marks for easy identification and management.

Choose the appropriate shipping vehicle based on the size, weight and quantity of aluminum battery cases. During transportation, try to avoid the aluminum battery casing from being exposed to moisture, sunlight, or extreme temperatures to prevent problems such as oxidation and deformation. If the packaging of the aluminum battery casing or product damage is found to be damaged during transportation, feedback should be reported to the logistics company in a timely manner and corresponding processing and claims should be made.
