- High Price, Low Return: Generic Chinese castings often cost 15‑20% more after hidden re‑work.
- Frequent Cracks & Warping: Inferior alloys cause thermal fatigue, leading to engine downtime.
- Compliance Risks: Non‑certified parts may fail EPA, CARB, or EU emission tests.
- Long Lead Times: Traditional suppliers average 45‑60 days, delaying production schedules.
Imagine: a batch of 1,000 units returning to the factory for re‑machining—an average loss of $120,000 per project.
