- High Unit Cost: Average market price for off‑the‑shelf t4 housings exceeds $120 / pcs, eroding profit margins.
- Inconsistent Quality: 22 % of buyers report premature cracks under 800 °C, leading to warranty claims.
- Long Lead Times: Typical Chinese suppliers need 6‑8 weeks, delaying production schedules.
