Fully Automated Production of Bridge-Riveted AA Battery Connectors

Our universal AA battery contact springs, produced via full automation and bridge riveting, achieve a balance of capacity, quality, and reliability: daily output exceeds 2 million sets, with zero risk of spring detachment. Their high flatness and verticality facilitate excellent soldering, and they pass rigorous 24-hour salt spray testing.

Product Application

Utilizing our self-developed smart equipment, the bridge riveting process for springs is entirely hands-free

Application

We rely on self-developed intelligent production equipment as the core, adopting bridge riveting technology to ensure fully automated and highly consistent spring assembly. More than 40 machines operate in coordination, supporting a robust daily delivery capacity of over 2 million sets.

Application

Using bridge riveting technology, the spring remains secure and never loosens. Strict control over verticality and flatness provides reliable support for automated assembly.

Fully Automated Production of Bridge-Riveted AA Battery Connectors

Application

Every model of universal AA battery contact spring is developed through strict material and process selection, achieving tiered salt spray corrosion resistance of 24, 48, or 72 hours. Additionally, each plated batch is required to pass solderability testing to validate its performance.
