Your EV battery busbar drawing is the starting point. We turn it into a stamped part that meets your dimensional and electrical specs. Every batch is verified before shipment. You get parts that fit your assembly line the first time.

1. Batch-traceable quality Each lot gets a unique batch number. We store material certs, inspection records, and process parameters for 5 years. If a field issue appears, we trace it back to the exact coil and die station. No guesswork.
2. Inspection report per batch You receive a full inspection report with every shipment. It includes dimensional data, surface finish readings, and material hardness results. Our QC team uses a 2.5D optical projector and CMM for verification. We do not ship without this report.
3. One factory for CNC + stamping + springs + heat sinks Your busbar might need a threaded insert, a spring contact, or a heat sink attached. We do all of it under one roof. No multiple vendors, no shipping delays, no tolerance stacking between suppliers. You send one drawing, we manage the rest.
Our custom metal stamping busbars go into real EV systems. Here is where they work daily:
These parts see vibration, thermal cycling from -40°C to +85°C, and high current loads. Our stamping process ensures consistent cross-section and surface conductivity.
Looking for a different part? We also machine Precision Stamped Electronic Brackets | Custom Metal Stamping, No MOQ in the same Dongguan factory.
Q: What is your MOQ? A: No MOQ. We accept prototype orders of 1–10 pieces for fit testing. Production orders start at any quantity. Tooling cost is quoted separately for custom dies, but we share it across your first production run if you order over 5,000 pieces.
Q: How do you guarantee tolerance and quality? A: We use progressive dies with in-die sensors for real-time monitoring. Critical dimensions are checked 100% with automated optical inspection. Our standard tolerance is ±0.05 mm, and we hold ±0.02 mm on request. Every batch ships with a dimensional report.
Q: What is your lead time for stamped busbars? A: Prototypes: 7–12 days after drawing approval. Production: 15–20 days for standard copper thicknesses. If you need faster, we can expedite with a 30% surcharge. We also keep common copper strips in stock for quick turnaround.
Q: Do you provide material certificates? A: Yes. Every coil we use comes with a mill certificate. We provide a copy with each shipment. For automotive projects, we also supply PPAP Level 3 documentation on request.
Send us your PDF or STEP file. We will review the geometry, suggest material and plating options, and give you a firm quote within 12 hours. No obligation, no design fee for standard reviews.
Precision manufacturing is our core. Custom metal stamping is what we do daily. Made in China, but with quality you can verify.
