Your connector design is unique. Your pin geometry, plating thickness, and mating cycle requirements are not off-the-shelf. We build them to your drawing, not from a catalog. Every stamped pin and socket is verified for critical dimensions before shipment.
At a glance: ±0.01 mm stamping tolerance, 7-day standard lead time, no MOQ, 100% inspection report per batch. This is precision manufacturing for engineers who need reliable, repeatable electrical contacts.
We are BQUQ, a factory in Dongguan, China, with 20 years in metal stamping. We also run CNC machining, springs, and heat sinks lines under one roof. Send us your drawing. We will tell you if it can be stamped faster and cheaper than machined.
| Parameter | Value |
|---|---|
| Material | Brass (C2600, C2680), Phosphor Bronze (C5210, C5191), Beryllium Copper (C17200), Stainless Steel (SUS301, SUS304) |
| Thickness Range | 0.05 mm – 3.0 mm |
| Tolerance (Critical Dims) | ±0.01 mm (with high-speed progressive die) |
| Tolerance (Standard Dims) | ±0.05 mm |
| Surface Finish | Selective gold, silver, tin, or nickel plating (per MIL or ASTM spec) |
| Lead Time | 7 days for standard tools; 15 days for new progressive dies |
| Batch Size | 1,000 to 10,000,000 pieces; no MOQ |
| Inspection | 2.5D optical projector, CMM, salt spray test, contact resistance test |
| Tooling Life | 50–100 million strokes on carbide dies |
| Secondary Ops | Coining, bending, tapping, riveting, automated assembly |
All materials are sourced with full mill certificates. We stock C5210 and C17200 in-house for fast starts. If you need a specific temper (1/2H, 3/4H, full hard), we order it in 3 days.
1. Batch-traceable quality. Each lot gets a unique heat number and die number. If a pin fails in your field, we trace it back to the coil, the die station, and the operator. No guesswork.
2. Inspection report per batch. You do not have to trust us. Every shipment includes a dimensional report, plating thickness report, and material cert. For high-volume runs, we include SPC data on critical dimensions like pin width and coplanarity.
3. One factory for CNC + stamping + springs + heat sink. Your connector housing needs a stamped contact, a CNC-machined alignment pin, and a compression spring. We make all three. You get one purchase order, one quality system, one shipping point. This cuts your supplier management time in half.
Stamped connector pins and sockets are the backbone of electrical interconnects. We supply them for:
If your part is currently machined or turned, ask us for a stamping review. We often convert round pins to stamped flat pins with a coined tip, cutting cost by 40% at high volume.
Looking for a different part? We also machine Precision EV Charging Connector Terminals | Custom Metal Stamping, No MOQ in the same Dongguan factory.
Q: What is your MOQ? A: No MOQ. We run 1,000 pieces for prototyping and 1,000,000 for production. Tooling cost is amortized into the piece price for small batches. For large batches, tooling is free with a volume commitment.
Q: How do you guarantee tolerance and quality? A: We use carbide progressive dies with in-die sensors. Critical dimensions are checked every 30 minutes during production. A final 2.5D optical inspection covers 100% of parts for visual defects and key dimensions. You receive the report with your shipment.
Q: What is your lead time? A: For existing dies, 5–7 days. For new custom metal stamping dies, 15 days for design and build, then 3 days for sample approval. We use 3D die design software and wire-cut EDM, so first articles are right the first time.
Q: Can you provide material certificates and RoHS/REACH compliance? A: Yes. Every coil comes with a mill test certificate. We also provide RoHS, REACH, and Conflict Minerals declarations on request. Plating thickness is verified with X-ray fluorescence (XRF) and reported per batch.
Stop guessing if your pin can be stamped. Send us your 2D drawing or 3D model. We will review the geometry, material, and plating. You will get a firm quote in 12 hours, including tooling cost, piece price, and lead time. No obligation.
This is custom metal stamping made in China, but with the engineering rigor you expect from a local shop. We speak English, we respond fast, and we ship worldwide via DHL or FedEx.
