- High Unit Price: Traditional suppliers charge 15‑25% above market, eroding ROI.
- Inconsistent Quality: Cracks, dimensional drift, and poor surface finish cause re‑work and downtime.
- Long Lead Times: 6‑8 weeks for custom caps delays plant commissioning.
- Limited Customization: OEM/ODM options are often “one‑size‑fits‑all,” restricting design flexibility.
- Regulatory Uncertainty: Missing CE, ISO, or RoHS certifications stalls import clearance.
According to a 2025 industry survey, **37 % of purchasing managers** cited “price volatility” as the top barrier to project success. If these issues sound familiar, read on.
