1. High Unit Cost – Many suppliers charge premium prices for low‑volume orders, inflating your BOM.
2. Inconsistent Dimensional Tolerance – Deviations beyond ±0.05 mm cause line stoppages and re‑work.
3. Long Lead Times – Overseas logistics often exceed 45 days, delaying new product launches.
4. Limited Material Choices – Lack of stainless‑steel or alloy options reduces durability in harsh environments.
5. Poor After‑Sales Support – No technical assistance leads to costly troubleshooting on the shop floor.
