The Real Costs Behind Low‑Quality Blanking Caps
- High Price, Low Return: Generic caps cost up to 40% more than a quality‑assured 30mm blanking cap.
- Frequent Breakage: Sub‑standard alloys cause up to 12% production loss per month.
- Long Lead Times: Overseas suppliers often need 45‑60 days, delaying your schedule.
- Regulatory Risks: Non‑compliant parts can trigger CE or FCC penalties, adding hidden expenses.
Result: Your operation faces reduced throughput, higher scrap rates, and missed market windows.
