What tolerance can you guarantee for aerospace components?

Standard tolerance is ±0.01 mm, while critical features can reach ±0.002 mm with CMM verification. Small precision parts like fasteners are produced on Swiss-type lathes. Reference: ASTM Aerospace Materials.

Do you support prototyping before scaling up?

Yes. We combine 3D Printing for quick validation with Rapid Tooling for functional test molds, helping aerospace teams shorten development time.

Can you provide tooling and molding for aerospace suppliers?

Yes. Many aerospace customers also require plastic housings and fixtures. We offer Export Mold Production and Injection Molding to deliver one-stop solutions.

What aerospace parts do you commonly make?

Typical parts include fasteners, optical mounts, UAV brackets, precision housings, connectors, and test fixtures. Depending on geometry and lead time, we may combine Sand Casting or Vacuum Casting with CNC finishing.

What inspection documents do you supply with shipments?

CMM reports, surface roughness results, hardness tests, and full material traceability certificates are included with each aerospace order. Our processes follow AS9100 requirements; see IAQG – AS9100.

What are your typical lead times for prototypes and small batches?

Prototypes: 7–10 working days; small batches (50–500 pcs): 15–20 working days. Lead time is reduced by combining Rapid Tooling, 3D Printing, and 5-Axis CNC.

Do you support cost-effective methods for non-critical aerospace parts?

Yes. For ground testing, training equipment, or UAV non-structural parts, Vacuum Casting or Sand Casting can lower cost while keeping reliability.
