Purchasing managers frequently encounter these three critical pain points:
- High Unit Cost: Conventional suppliers charge a premium for 15mm copper caps, eroding your product margins.
- Inconsistent Quality: Dimensional variance (> ±0.15 mm) leads to re‑work, downtime, and warranty claims.
- Long Lead Times: 6‑8 weeks from order to delivery hampers agile production schedules.
According to a 2025 IDC survey, 42 % of manufacturers cite “unreliable component supply” as the top barrier to scaling output.
