FAQ
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?
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)?
10. How do I request a quote?
