Why Purchasing Managers Struggle with Traditional Transformers

High Unit Cost: Average market price is 20‑30% above OEM benchmarks.
Inconsistent Quality: 12% of shipments fail ISO‑9001 audit, causing re‑work.
Long Lead Times: 6‑8 weeks from order to delivery in most Chinese factories.
Limited Customization: Standard catalog items cannot meet niche medical or new‑energy specs.
Regulatory Uncertainty: Missing CE/FDA/ROHS certifications leads to customs delays.

Result: Production bottlenecks, inflated OPEX, and missed market windows.
