FAQ

Frequently Asked Questions

Quick answers on ordering automotive cable assemblies from SAOJIE.

Can you make automotive harnesses to our drawings or samples?

Yes. We build from your drawing, BOM or a physical sample — from prototype batches of around 50 units to full production runs, with APQP/PPAP documentation available on request for OEM programs.

Do you support low-volume or pre-production runs?

Absolutely. We keep flexible MOQs for automotive customers, typically 50-200 pcs for prototypes and ramping orders, so you can validate tooling and quality before committing to volume.

What about high-voltage EV harnesses?

Our HV line covers 400-800V platforms with HVIL interlock, orange outer jacket, fully shielded conductors and laser-marked labels, each piece tested to 100% hi-pot and insulation resistance before packing.
