- High Price Tags: Overseas suppliers often add 30‑50% markup for small‑batch orders.
- Inconsistent Quality: Lack of ISO certifications leads to dimensional variance > 0.2 mm.
- Long Lead Times: Shipping from Europe or the US can add 4‑6 weeks before the first sample arrives.
- Limited Material Choice: Many vendors only offer aluminum, ignoring cast iron or stainless steel needs.
According to the 2025 Foundry Industry Report, 57% of purchasing managers cite “unpredictable delivery” as the top barrier to scaling production.
