Your relay lives or dies by the contact reed. We make sure it lives.
We stamp relay contact reeds exactly to your drawing. Tolerances are held, burrs are controlled, and every batch is checked before it leaves our floor. You get parts that seat, weld, and switch consistently—verified before shipment.
| Parameter | Value | Notes |
|---|---|---|
| Materials | Beryllium copper (C17200), phosphor bronze (C5210), brass (C2600), stainless steel (301/304), silver-nickel (AgNi), silver-tin oxide (AgSnO2) | In-house sourcing, mill certs available |
| Process | Progressive die stamping, high-speed stamping (up to 800 SPM), four-slide stamping for complex bends | Tooling built in-house, 20+ years die design experience |
| Tolerance | ±0.01 mm on hole-to-hole and edge-to-edge; ±0.02 mm on bend radii | Measured with CMM and optical comparator |
| Surface finish | Ra 0.4 µm max on contact area; optional gold, silver, or tin plating (0.1–2.0 µm) | Plating done by certified partners, adhesion tested |
| Burr control | Burr height ≤ 0.03 mm on cut edges; secondary deburring available | Per DIN 267 or your internal spec |
| Batch size | 100 to 5,000,000 pieces | No MOQ, but tooling amortization applies for small runs |
| Inspection | 100% dimensional check on first article; AQL 0.65 for production lots | Full inspection report shipped with every order |
1. Batch-traceable quality. Each lot gets a unique heat number and production code. If a part fails in your assembly, we can trace it to the exact coil, die, and shift. No guesswork. No blame games. Just data.
2. Inspection report per batch. You don’t have to ask for it. Every shipment includes a dimensional report, material cert, and surface finish check. Your incoming QC signs off in minutes, not days.
3. One factory for CNC + stamping + springs + heat sinks. Your relay housing needs a stamped contact, a CNC-machined base, a precision spring, and a heat sink. We make all four under one roof. Fewer vendors, less logistics, one accountable partner. That’s precision manufacturing without the runaround.
Our stamped relay contact reeds go into applications where failure is not an option.
If your part switches current, chances are we’ve stamped something similar. Send us your drawing and we’ll tell you if it’s feasible—within 12 hours.

Q: Is there really no MOQ? A: Correct. No MOQ for custom metal stamping. You can order 100 pieces for a prototype or 1,000,000 for production. Tooling cost is quoted separately and amortized over your first production run if you order more than 50,000 pieces.
Q: How do you guarantee ±0.01 mm tolerance? A: We use progressive dies with precision ground punches and die buttons. First articles are measured on a CMM with 0.001 mm resolution. During production, we check every hour with optical comparators. If a dimension drifts, we stop the press and adjust—not after 10,000 bad parts, but immediately.
Q: What’s your typical lead time for stamped parts? A: Prototypes: 7–12 days after drawing approval. Production: 15–20 days, depending on material availability and plating requirements. For urgent orders, we can expedite to 5 days on prototypes at a 15% surcharge.
Q: Do you provide material certificates and RoHS/REACH compliance? A: Yes. Every batch ships with a mill certificate for the raw material, plus a declaration of RoHS and REACH compliance. If you need IMDS or PPAP documents, we provide those too—just specify at order time.
