- High Price – 15‑30% above market average for comparable alloys.
- Inconsistent Quality – Dimensional tolerances often exceed ±0.5 mm, leading to re‑work.
- Long Lead Times – 6‑8 weeks from order to delivery, jeopardizing production schedules.
- Limited Material Choices – Few suppliers can offer both aluminum and stainless‑steel in one contract.
According to a 2025 IndustryWatch survey, 42% of U.S. manufacturers cite “unreliable casting quality” as the top barrier to scaling production.

Frequently Asked Questions
What is sand casting and how does it differ from die casting?
Sand casting uses a granular sand mould that can be reused many times, ideal for low‑to‑medium volume runs and large‑size parts. Die casting employs a permanent metal die, offering higher repeatability but higher tooling cost, best for very high‑volume production.
Can YD produce custom alloys for aerospace applications?
Yes. Our metallurgical team can formulate Al‑Si, Al‑Mg, or high‑strength stainless‑steel alloys meeting AMS and ASTM standards. Sample testing is provided within 7 days.
What is the typical lead time for a 5 kg aluminum casting?
Standard lead time is 30 days, including pattern making, mold preparation, pouring, and first‑article inspection. Expedited 15‑day service is available at a 12% surcharge.
How does YD handle quality inspection for overseas shipments?
Each batch undergoes ISO‑based dimensional checks, non‑destructive testing (NDT), and a third‑party inspection report (SGS/Intertek) before loading. Documentation is included with the commercial invoice.
What payment terms does YD offer to U.S. buyers?
Standard terms are 30 % T/T in advance, 70 % against copy of Bill of Lading (B/L). For qualified accounts we accept LC, DP, or Net‑45 days after delivery.
