Your drawing defines the part. Our job is to hit it exactly—every time. We are BQUQ, a precision manufacturing factory in Dongguan, China, with 20 years in metal stamping. We make stamped contact springs to your print, not from a catalog.
Every batch is verified before shipment. You get parts that fit, function, and survive repeated cycles. No surprises on your assembly line.
At a glance: ±0.01 mm tolerance on critical features, 3–7 day lead time for prototypes, no MOQ, full material traceability.
100% dimensional check on critical features, CMM report per batch
Lead time
3–7 days (prototype), 10–15 days (production)
Certifications
ISO 9001:2015, IATF 16949 (automotive line), RoHS/REACH compliance
We run both progressive and transfer dies. For contact springs, we use high-speed presses with precision straighteners and feeders. This holds flatness and pitch consistency across long runs.
Three reasons buyers send us their drawings
1. Batch-traceable quality. Each lot gets a unique number. We track material heat, die settings, and operator shifts. If a problem appears in your field, we trace it back in minutes, not weeks. You get a full inspection report per batch—dimensions, material cert, surface condition.
2. Inspection report per batch. We do not guess. Our QC lab uses CMM, optical projectors, and hardness testers. Every batch ships with a report showing measured values against your tolerances. You can skip incoming inspection if you trust our data. Many customers do.
3. One factory for CNC + stamping + spring + heat sink. Your stamped contact spring often sits next to a CNC-machined housing or a heat sink. Send us the whole assembly. We coordinate processes internally, cut your logistics cost, and reduce tolerance stack-up between parts. One supplier, one invoice, one responsible party.
Where these parts are used
Stamped contact springs show up where electrical continuity and mechanical force meet. Common applications:
Medical devices: disposable sensor contacts, low-current signal springs
Telecom: RF shielding clips, antenna contact springs, base station connectors
These parts carry current, hold position, and survive thousands of cycles. Our material selection and heat treatment ensure consistent spring force—not just at first insertion, but after 10,000 cycles.
Q: What is your MOQ?
A: No MOQ. We prototype with 100 pieces and scale to millions. You pay a small setup fee for small batches, but the unit price drops predictably as volume grows.
Q: How do you guarantee tolerance and quality?
A: We run SPC on critical dimensions. Our die maintenance schedule is strict—after every 50,000 strokes, we check wear. In-process inspection every hour, plus final CMM report per batch. If we miss your spec, we re-run at no cost.
Q: What is your lead time?
A: Prototype in 3–7 days from drawing approval. Production in 10–15 days. For urgent needs, we have a 48-hour express service on simple parts. We quote real dates, not optimistic ones.
Q: Do you provide material certificates?
A: Yes. Every batch ships with mill certificates for raw material, plus our own chemical analysis if required. We also provide RoHS, REACH, and conflict-free declarations on request.
