Frequently Asked Questions
1. What materials do you use?
We primarily use 304, 316, and 316L stainless steel for corrosion resistance and durability. Other grades (e.g., 303, 17-4PH) are available upon request.
2. What tolerances can you achieve?
- Standard: ±0.05-0.1 mm (ISO 2768-medium/fine)
- Tighter tolerances (e.g., ±0.01 mm) are possible for critical dimensions
3. Can you customize parts?
Yes! We offer:
- Custom sizes, thicknesses, and hole patterns
- Special surface finishes (e.g., mirror polish, sandblasting)
- Additional features (threads, grooves, knurling)
4. What's the lead time?
Bulk orders: 30-45 days (depends on quantity)
5. How do you ensure quality?
- CNC machining with ISO 9001-certified processes
- Dimensional checks (CMM, calipers) and surface finish testing
- Material certifications (MTRs) provided
6. Are your parts corrosion-resistant?
Yes! Stainless steel (especially 316/L) offers excellent resistance to rust, chemicals, and high temperatures (up to 800°C/1472°F).
7. What industries do you serve?
Common applications include:
- Automotive (bushings, bearings)
- Aerospace (flange connectors)
- Hydraulics/Pneumatics (seal sleeves)
8. Do you provide coatings or treatments?
Options include:
- Passivation (enhanced corrosion resistance)
- Electropolishing (smoother surface)
- Heat treatment (for hardness)
9. What's the minimum order quantity (MOQ)?
- Bulk orders: 1000 pieces
- Negotiable (discounts for large quantities)
10. How do I request a quote?
Send us:
- Drawings (CAD/PDF preferred)
- Material, quantity, and surface finish requirements
