Your drawing defines the part. Our job is to hit every dimension on it, then prove it before shipment.
We run a 20-year-old precision manufacturing factory in Dongguan, China. Our metal stamping line produces brass electrical terminals and contacts from 0.05 mm to 3.0 mm thick strip. Tolerances hold to ±0.01 mm on critical features.
We verify every batch with a coordinate measuring machine (CMM) and a 2.5D optical projector. You get a full inspection report with the shipment. No surprises.
| Parameter | Value |
|---|---|
| Material | Brass C2600 (CuZn30), C2680, C5191, or customer-specified |
| Thickness range | 0.05 mm – 3.0 mm |
| Tolerance (critical) | ±0.01 mm |
| Tolerance (general) | ±0.05 mm |
| Minimum feature size | 0.3 mm hole, 0.2 mm bend radius |
| Process | Progressive die stamping, compound die stamping, four-slide |
| Die life | 500,000 – 2,000,000 strokes (tool steel), >5M (carbide) |
| Surface finish | Bare bright, nickel, gold, silver, tin plating (selective or full) |
| Deburring | Barrel tumbling, vibratory finishing, or manual for tight spots |
| Batch size | No MOQ; prototype to high-volume |
| Inspection | 100% critical dimension check, CMM + optical projector per batch |
| Lead time | Prototype: 7–15 days; Production: 15–25 days after approval |
| Packing | Anti-static bags, compartment trays, tape-and-reel (optional) |
1. Batch-traceable quality. Every lot gets a unique batch number. We record material heat number, die settings, and inspection results for that batch. If a problem appears in your assembly line, we trace it back to the exact stamping run within 24 hours. No guesswork.
2. Inspection report per batch. We do not ship blind. Each batch includes a dimensional report with CMM data and optical projector readings. You see the actual measured values, not just a pass/fail stamp. For critical automotive or medical parts, we add full material certificates and plating thickness reports.
3. One factory for CNC + stamping + spring + heatsink. Your terminal might need a stamped contact, a CNC-machined housing, a spring, and a heatsink. We make all four under one roof. That means one purchase order, one quality system, one shipping date. You save on logistics and avoid tolerance mismatches between suppliers.
Our stamped brass terminals and contacts go into real products that run 24/7.

Q: What is your MOQ? A: No MOQ. We run prototype batches from 100 pieces. Production orders scale to millions per month. Tooling cost is quoted separately and amortized over your order volume.
Q: How do you guarantee tolerance and quality? A: We use progressive dies ground to ±0.005 mm. First-article inspection covers all dimensions. During production, we check every 500 pieces with a 2.5D projector. Final batch inspection uses CMM and includes a written report.
Q: What is the lead time for a custom part? A: Prototype (no tooling modification) is 7–15 days. New progressive die tooling takes 20–30 days. Production runs ship 15–25 days after you approve the sample. We quote exact dates after reviewing your drawing.
Q: Do you provide material certificates? A: Yes. We supply mill test certificates for brass strip, plating thickness reports, and RoHS/REACH declarations. For automotive or medical, we add PPAP Level 3 documentation on request.
Email your 2D or 3D file (PDF, DXF, STEP, or IGES). We review tolerances, material, and plating within 4 hours. You get a firm quote in 12 hours—price, lead time, and tooling cost if needed.
This is custom metal stamping made in China with no MOQ and full traceability. Send your drawing, and we will make it right.
