Project Background
Earlier this year, a domestic new energy vehicle startup approached us to mass-produce aluminum alloy end plates for their electric vehicle battery packs. The customer required:
- Surface flatness: Not exceeding 0.02mm
- Dimensional tolerance: ±0.05mm
- Monthly demand: 5,000 pieces
With the customer’s new vehicle model about to launch, the delivery timeline was extremely tight.
Customer's Challenges
The customer’s previous supplier could not meet the monthly demand due to insufficient production capacity. Additionally, the defect rate was consistently high (around 5%). The customer needed a reliable supplier who could meet the demands without impacting the production timeline for the new vehicle model.
Our Solution
We evaluated our production capacity and confirmed that our factory, with three CNC machining centers, could fully meet the customer’s 5,000-piece monthly demand. We optimized the process as follows:
- Pre-stretching the blanks: To eliminate internal stresses.
- Vacuum suction fixtures: To ensure flatness during machining.
- Specialized inspection tools: For quick checks to improve efficiency and ensure dimensional consistency.
We also obtained IATF16949 certification, which satisfies the automotive industry’s batch production quality management requirements. Every batch comes with complete quality records.
