Why Your Production Line Is Suffering
Even a small component such as a 20mm end cap can become a bottleneck when it fails to meet the following realities:
- High Unit Price – Imported caps often cost 30‑40% more than domestically‑produced equivalents.
- Inconsistent Quality – Dimensional variance > 0.15 mm leads to assembly re‑work and scrap.
- Long Lead Times – Typical shipping from overseas exceeds 45 days, disrupting JIT schedules.
- Limited Customization – Standard catalog items cannot accommodate special threading or surface‑treatment requirements.
- Regulatory Uncertainty – Lack of CE, RoHS or ISO‑9001 certification can stall cross‑border procurement.
According to a 2025 survey by the International Manufacturing Association, 62% of procurement managers cited “component price volatility” as a top risk factor for project overruns.
