Aluminum alloy connector spring contacts are key components for lightweight electrical connection and signal transmission. Featuring good conductivity, light weight and high formability, aluminum alloy has become an ideal material for lightweight connector design. This project adopts high-precision progressive stamping to realize integrated forming including punching, bending and shaping, ensuring stable contact force, excellent dimensional accuracy and consistent product performance.
Technical Solution & Implementation
We developed a customized multi‑station progressive stamping die with high‑precision guide posts and pilot positioning to ensure feeding accuracy.
Key technical measures include:
- CAE forming simulation to predict and compensate material springback
- Multi‑stage bending and shaping processes to reduce deformation
- Automatic production flow: leveling → punching → bending → shaping → cutting
- Online dimension monitoring and real‑time quality control
This integrated process achieves fully automated continuous production with stable performance in long‑term mass production.
