Production Workshop
(1) Material Properties
When producing products such as Copper and Aluminum Bimetal Bipolar plates and Lithium Battery Top caps, high-quality metal coils are strictly selected to ensure material performance from the source and lay a solid foundation for creating high-quality battery cover plates.
(2) Production Process Flow
Aluminum Case Drawing: Through the aluminum case drawing process, give the battery cover plate an appropriate shape and strength to meet the assembly needs of battery cells.
Ultrasonic Cleaning: Perform ultrasonic cleaning on the processed components to completely remove impurities, ensure the cleanliness of the cover plate surface, and improve product quality.
In-mold Injection of Cover Plates: Monitor the accuracy and quality in real-time during the injection process to ensure the stability and reliability of the cover plate injection link.
(3) Quality Control Key Points
Strict standards and inspection procedures are set for each process. In key links such as in-mold injection of cover plates, parameters are monitored in real-time, and quality deviations are discovered and corrected promptly to ensure product consistency.
(4) Product Advantages
Reasonably plan the workshop layout and optimize the production process, which not only improves production efficiency but also ensures product stability and consistency. The produced lithium battery cover plates, including Top Lid For Prismatic Battery Cell and Power Battery Cover Plate, are highly competitive in the market, provide reliable components for customers, and contribute to the production of new energy batteries.

Packing and Delivery
1. Packing Process
We create a professional packaging system for products like lithium battery cover plates to ensure transportation safety:
| Inner Protection | Use Inner Plastic Bag & Box Packing, which fits the product size, isolates dust and minor impacts, and protects precision components such as the Top Lid For Prismatic Battery Cell. |
| Middle-layer Reinforcement | Select 3 - 3-layer Corrugated Paper Carton with good compression resistance to disperse external impact; add tie reinforcement at key parts to enhance overall stability. |
| Outer moisture-proof | Wrap pallets with Pallet Moisture-proof Stretch Film, suitable for long-cycle logistics such as sea and railway transportation, resisting moisture and salt spray erosion, and protecting the performance of products like Power Battery Cover Plate. |
2. Delivery Modes
Rely on a diversified logistics network to flexibly match delivery needs:
Express Services: Deeply cooperate with DHL, UPS, EMS, Aramex, TNT, and FedEx, covering many places worldwide, meeting small-batch and urgent orders, and quickly delivering goods such as Aluminum Cover Plate for Batteries.
Sea/China Railway Express: For large-batch orders, use methods like sea freight containers and China-Europe freight trains to reduce logistics costs, stably transport heavy-duty/bulk goods such as Copper and Aluminum Bimetal Bipolar Plate, and balance economy and timeliness.
From fine packaging to diversified transportation, the whole process protects product safety and helps customers receive goods efficiently!
