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.
Tolerance: ±0.01 mm (critical), ±0.05 mm (general)
Lead time: 7–15 days for prototypes, 15–25 days for production
No MOQ—order 100 or 100,000 pieces
Material: Brass C2600, C2680, C5191, or your specified grade
Surface: Selective gold/silver/tin plating, or bare bright finish
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.

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.
Where these parts are used
Our stamped brass terminals and contacts go into real products that run 24/7.
Automotive connectors: ECU pins, headlamp sockets, relay contacts. Brass carries current reliably at 85°C under vibration.
Industrial relays and switches: Contact springs and fixed terminals for control panels. We hold flatness to 0.02 mm so the relay seats correctly.
Consumer electronics: Battery contacts, USB connector pins, SIM card holders. Thin brass (0.1–0.2 mm) gives spring-back for repeated insertion.
Power distribution: Busbar connectors, fuse clips, terminal blocks. Tin-plated brass resists corrosion in humid panels.
Medical devices: Low-current sensor contacts. We clean and passivate to avoid ionic contamination.
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.
