- High Unit Price: Imported caps often carry a 20‑30% premium due to middle‑man mark‑ups.
- Inconsistent Dimensional Tolerance: Deviations > ±0.15 mm lead to assembly re‑work.
- Low Material Strength: Cracks under cyclic loading cause unexpected downtime.
- Long Lead Times: 6‑8 weeks from order to delivery hampers production schedules.
- Limited Customization: Standard catalog parts cannot meet unique flange or bore requirements.
Result: Your OPEX rises, inventory turns slower, and product quality suffers.
