1. High price volatility – Overseas suppliers often charge 15‑25% above market rates, inflating your BOM.
2. Inconsistent quality – Dimensional drift > 0.2 mm leads to re‑work and production downtime.
3. Long lead times – Traditional foundries need 4‑6 weeks, jeopardizing tight project schedules.
4. Limited customization – Standard catalogs lack the flexibility for complex geometries or special heat‑treatment cycles.
5. Regulatory uncertainty – Missing CE, RoHS, or FDA documentation can delay product launch in regulated markets.
Result: Your engineering team spends extra hours on redesign, your finance department fights cost overruns, and your market launch is delayed.
