- High Unit Cost: Generic end caps often exceed budget by 15‑25%.
- Inconsistent Quality: Dimensional tolerance > ±0.2 mm leads to assembly rejects.
- Long Lead Times: Overseas suppliers average 30‑45 days, causing line shutdowns.
- Limited Customization: Off‑the‑shelf designs rarely match your specific flange or material needs.
- Regulatory Risks: Missing certifications (CE, RoHS, ISO 9001) can halt shipments.
Result: Production delays, higher scrap rates, and eroded profit margins.
