FAQs
What is your minimum order quantity (MOQ)?
No MOQ for prototype development. For production runs, we recommend 1,000+ pieces, but we’re flexible — smaller batches are negotiable, especially for low‑volume or specialty programs.
Can you handle both prototyping and high‑volume production?
Yes. We support the full lifecycle — from rapid prototypes (2‑4 weeks) to pilot runs and mass production. Same team, same quality standards, seamless transition.
What materials do you work with for EV components?
We work with 40+ certified alloys including aluminum (A356, 6061), stainless steel (304, 316), nickel‑based superalloys, and specialty composites. All materials are ASTM/SAE/OEM compliant with full traceability.
What tolerances can you achieve?
Investment casting: CT5‑7 (ISO8062). 5‑axis CNC machining: ±0.003mm positional accuracy. Surface finish: Ra ≤ 0.8 for machined surfaces, Ra 3.2‑6.3 for as‑cast.
Do you provide design for manufacturability (DFM) support?
Absolutely. Our engineering team reviews your drawings early, identifies cost‑saving opportunities, and suggests geometry optimizations to improve castability and reduce secondary operations.
What is your typical lead time?
Prototypes: 2‑4 weeks. Production tooling: 3‑5 weeks. Volume production: 4‑6 weeks after PPAP approval. Expedited options available for urgent programs.
Do you offer post‑casting services like heat treatment or surface finishing?
Yes — one‑stop service. We provide heat treatment, electropolishing, anodizing, powder coating, sandblasting, plating, and secondary machining.
Ready to optimize your chassis structural parts supply chain?
From prototype to production, we deliver reliable, scalable manufacturing solutions for chassis and structural parts.
