FAQ
1
Q: Which materials do you use?
A: Primarily aerospace-grade 7075-T6 aluminum, with 6061-T6, 5052-H32 and carbon fiber options. 7075 delivers high strength-to-weight ratio; our stress-relief process prevents post-machining distortion.
2
Q: What tolerances can you hold?
A: Standard: ±0.002mm form, ±0.005mm dimension, Ra≤0.02μm mating surfaces. Critical joints: ±0.0005mm geometric tolerance, <1 arcmin backlash.
3
Q: Do you provide traceability and certifications?
A: Yes. Full MTRs (EN 10204 3.1) + heat treatment records per batch, 100% CMM inspection. ISO 9001:2015 certified; FAIR and surface treatment reports available.
4
Q: What's the prototype lead time?
A: 7–10 business days post drawing approval (depends on finishing). Free DFM feedback within 48h; rush orders delivered in 48h.
5
Q: Can you make integrated hollow structures and surface treatments?
A: Yes. One-piece hollow forming with ≤0.001mm coaxiality. Offer hard anodizing, DLC coating and passivation for enhanced durability.
