- High Unit Price: Most overseas suppliers charge > $4.50 per cap, inflating BOM.
- Inconsistent Tolerances: ±0.10 mm variation leads to re‑work and line stoppage.
- Quality Defects: Porosity, surface cracks, and non‑conforming hardness cause warranty claims.
- Long Lead Times: 6‑8 weeks from order to delivery delays project schedules.
- Limited Customization: OEM/ODM options are rarely offered, forcing design compromises.
Result: Production efficiency drops by up to 22 %, and ROI suffers.
