Your battery connector drawing defines the part. We define the process to hit it. We run high-speed stamping presses with closed-loop tonnage monitoring. Every die is built in-house, so we control geometry from first hit to last. Before shipment, each batch goes through a 100% dimensional verification on a CMM. If the drawing says ±0.05 mm, we ship ±0.05 mm.
| Parameter | Value |
|---|---|
| Materials | C1100 copper, C5191 phosphor bronze, 301 stainless steel, brass, beryllium copper |
| Material thickness | 0.08 mm – 3.0 mm |
| Stamping process | Progressive die, deep drawing, coining, bending, punching |
| Machine capacity | 25-ton to 250-ton high-speed presses (up to 800 SPM) |
| Tolerance | ±0.05 mm standard; ±0.02 mm for critical contact surfaces |
| Surface finish | Tin plating (Sn 5–15 µm), silver plating (Ag 3–10 µm), nickel plating (Ni 2–5 µm), or as-drawn |
| Burr height | ≤ 5% of material thickness, per DIN 267 |
| Batch size | No MOQ – from 100 pieces to 1,000,000+ |
| Inspection | CMM, optical comparator, X-ray for plating thickness, salt spray test |
| Packaging | Anti-static trays, reel packaging (for SMT), or custom boxes per your spec |
1. Batch-traceable quality. Each lot gets a unique heat number and production timestamp. We store first-article inspection (FAI) reports for 5 years. If a field failure happens, we can trace the exact coil, press, and operator.
2. Inspection report per batch. You don't guess if the parts are good. We send a full inspection report with every shipment: dimensions, plating thickness, hardness, and visual check photos. For automotive-grade orders, we include PPAP Level 3 documentation.
3. One factory for CNC + stamping + springs + heat sink. Your connector assembly might need a stamped contact, a CNC-machined housing, a coil spring, and a heat sink. Instead of coordinating four suppliers, you send one drawing pack to us. We cut your logistics cost and shorten your lead time by 30–40%. This is precision manufacturing under one roof – made in China, but with German-style documentation.
Our stamped battery connectors go into systems where vibration and thermal cycling are brutal.
In these applications, a 0.01 mm deviation in contact surface can cause resistance rise, heat build-up, and eventual failure. We hold the tolerance so you don't have to worry about field returns.

Q: Do you really have no MOQ? A: Yes. We run small batches for prototyping and pilot runs. For a 100-piece order, the unit price is higher, but you get the same die quality and inspection rigor as a million-piece order. Once the die is proven, scaling to mass production takes 3–5 days.
Q: How do you guarantee tolerance on high-volume stamping? A: We use in-die sensors that measure material thickness and punch force every stroke. If a parameter drifts, the press stops automatically. Then we run a SPC check on the last 50 pieces before resuming. You get a CPK report for any critical dimension you specify.
Q: What is your typical lead time for custom metal stamping? A: For a simple flat part with no plating: 7 days from drawing approval. For a complex progressive die part with plating: 15–20 days. Die design takes 2 days, machining 5 days, trial hits 1 day, and production 3–7 days depending on quantity. We ship via DHL or FedEx for urgent orders.
Q: Can you provide material certificates? A: Yes. Every coil we buy comes with a mill test certificate (MTC) from the steel or copper mill. We copy the MTC number onto your packing list. For RoHS, REACH, and conflict-free mineral declarations, we provide a full compliance pack with each batch.
Stop comparing quotes from three different factories. Send us your 2D drawing or 3D STEP file, and we will do the rest. We will review the geometry, suggest material and plating options, and send you a firm quote within 12 hours.
