Even the most established foundries struggle with three critical pain points that erode your ROI:
- Escalating Material Costs: 17 4 stainless steel prices have risen 22 % YoY, yet many suppliers still charge a 35 % premium for casting services.
- Inconsistent Dimensional Accuracy: Tolerances beyond ±0.15 mm lead to re‑work, causing up to 18 % extra labor cost per batch.
- Lengthy Lead Times & Poor Communication: Average delivery exceeds 90 days; lack of real‑time order tracking adds hidden delays.
These issues translate directly into higher production costs, missed shipment windows, and weakened competitive advantage.

Frequently Asked Questions
What is the minimum order quantity for 17 4 investment casting?
We accept batches as low as 500 pcs for standard geometries. For complex, custom designs the MOQ is 250 pcs, enabling small‑batch production without price penalties.
Can you provide OEM/ODM design support for new parts?
Yes. Our in‑house CAD/CAE team works with you from concept to prototype, delivering fully validated 3‑D models and tooling recommendations within 10 business days.
How do you ensure dimensional accuracy across large batches?
Each casting undergoes in‑process 3‑D laser scanning; data is compared to the CAD model in real time. Statistical process control (SPC) guarantees ±0.08 mm tolerance.
What are the logistics options for US deliveries?
We offer FOB Shanghai, CIF Los Angeles, and DDP New York. Air freight (express) is available for urgent orders, with customs brokerage handled by our US partner.
Do you provide after‑sales technical support?
Our technical service team is on‑call 24 h (GMT+8). We assist with heat‑treatment parameters, post‑machining advice, and warranty claims (12‑month limited).
