Q
What corrosion resistance levels are available for these battery contacts?
We offer professional grading for different corrosion resistance requirements. Depending on the material combination selected, the contacts can pass neutral salt spray tests of 24 hours, 48 hours, or 72 hours. Each plated batch also includes a solderability test report.
Q
How does bridge riveting technology improve product quality?
Bridge riveting technology effectively solves common issues such as spring detachment and assembly misalignment. The resulting contacts achieve high verticality and excellent flatness, which are critical for reliable automated assembly and consistent electrical performance.
Q
Are these battery contacts compliant with environmental and safety regulations?
Yes. Our 18650 battery spring contacts are certified under both RoHS and REACH standards, ensuring they are free from hazardous substances and meet international environmental compliance requirements.
Q
What are the key advantages of your fully automated production process?
Our automated production process eliminates manual intervention in the spring riveting stage, which significantly reduces human error and improves consistency. Key benefits include higher output volume (2M+ units/day), improved dimensional accuracy, superior surface flatness, and better weldability — all backed by batch-level quality inspection reports.
