Your battery contact design deserves better than a generic catalog part. We build stamped contacts exactly to your drawing, with tolerances held to ±0.01 mm where required. Every batch is verified before shipment, not sampled. You get parts that fit your assembly the first time, without rework.
At a glance: ±0.01 mm tolerance capability, 5-day lead time on prototypes, no MOQ, 20 years of precision manufacturing experience in Dongguan, China.
Our stamping line runs 25 to 200-ton presses with high-speed feeders. We use progressive dies for complex geometry and compound dies for high-volume simple parts. All tooling is designed in-house and validated with first-article inspection.
| Parameter | Capability |
|---|---|
| Material thickness | 0.05 mm to 3.0 mm |
| Materials | Phosphor bronze, beryllium copper, brass, stainless steel 301/304, nickel silver, tin-plated steel |
| Tolerance | ±0.01 mm on critical dimensions, ±0.05 mm standard |
| Surface finish | As-stamped, selective plating (Au, Ag, Ni, Sn), passivation |
| Lead time | 5-7 days for prototypes, 15-20 days for production after tooling approval |
| Batch size | No MOQ, from 100 pieces to 5 million pieces per month |
| Inspection | 100% dimensional check on critical features, CMM reports per batch |
| Secondary ops | Tapping, riveting, bending, heat treatment, ultrasonic cleaning |
1. Batch-traceable quality. Every lot gets a unique batch number. We record material heat numbers, press settings, and inspection results for that batch. If a problem appears in your line, we trace it back to the exact coil and stroke count. No guesswork.
2. Inspection report per batch. You receive a full dimensional report with every shipment. Critical features are measured on a CMM and documented. We do not rely on spot checks. This is standard, not an extra-cost option.
3. One factory for CNC + stamping + spring + heat sink. Your battery contact often sits next to a spring, a heat sink, or a CNC-machined housing. Instead of coordinating three suppliers, send us the whole assembly. We control tolerances across mating parts and ship complete sub-assemblies. Fewer vendors, fewer delays, fewer tolerance stack-ups.
Battery contacts are everywhere, but the demanding ones share common traits: high cycle life, low contact resistance, and stable force over temperature.
Looking for a different part? We also machine Precision Stamped Brass Electrical Terminals Contacts Made to Drawing in the same Dongguan factory.
What is the minimum order quantity? No MOQ. We start at 100 pieces for prototypes and scale to millions per month. You pay a slightly higher unit price for small batches, but you never over-order.
How do you guarantee tolerance and quality? We use progressive dies with in-die sensors and optical inspection. Critical dimensions are measured on a CMM with a resolution of 0.001 mm. Every batch ships with a dimensional report. If a part is out of spec, we replace it at our cost.
What is the lead time for stamped battery contacts? Prototypes in 5-7 days after drawing review. Production tooling takes 15-20 days, then parts ship within 10 days. Rush service is available for urgent needs, with a confirmed schedule before you commit.
Do you provide material certificates? Yes. Every batch includes a mill certificate for the raw material, showing chemical composition and mechanical properties. We also provide plating thickness certificates when required. All documents are in English and traceable.
Stop comparing quotes from suppliers who cannot hold your tolerance. Send us your drawing and get a firm quote in 12 hours. We will review material options, tooling cost, and unit price based on your annual volume.
