Process & Manufacturing Insights
We utilize state-of-the-art sheet metal & stamping technology to produce our custom battery contacts. This process begins with precise die design and fabrication, leveraging our internal capabilities for custom tooling. Material selection is critical; we offer both phosphor bronze for excellent conductivity and corrosion resistance, and high-tensile spring steel for superior spring characteristics and structural strength, often coated for enhanced performance.
High-speed, multi-stage stamping presses accurately cut, bend, and form the complex geometry of the battery contact from continuous metal strips. This progressive stamping approach guarantees exceptional consistency, tight tolerances, and high production efficiency, even for large volumes. Our post-processing options include precise nickel plating, gold plating, or other surface treatments for optimal solderability, corrosion protection, and contact reliability. Every step is overseen by our rigorous quality control system to ensure error-free products.
