Why Purchasing Managers Struggle with Conventional Caps
- High Unit Price – Imported copper caps often carry a 30‑40% premium due to limited supply chains.
- Inconsistent Quality – 20% of shipments fail ASTM B101 standards, causing re‑work and production delays.
- Long Lead Times – Typical delivery exceeds 45 days, jeopardizing project schedules.
- Limited Customization – Fixed thread sizes and finishes force designers to redesign assemblies.
- Regulatory Uncertainty – Missing RoHS or CE certificates can stall cross‑border shipments.
