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.
Tolerance: ±0.05 mm standard, ±0.02 mm on critical features
Lead time: 7–12 days for custom prototypes, 15–20 days for production runs
No MOQ – order 100 pieces or 1 million
Material certs: mill test reports included with every batch
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
Three reasons buyers send us their drawings
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.
Where these parts are used
Our stamped battery connectors go into systems where vibration and thermal cycling are brutal.
EV battery packs: busbar connectors, cell-to-cell jumpers, high-voltage interlock loops
Energy storage cabinets: rack-mounted battery modules, DC bus connectors, fuse clips
Portable power tools: nickel-plated contact strips, spring-loaded battery terminals
Solar inverters: DC input connectors, battery disconnect terminals
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.
