Please send 2D drawings, 3D models or sample photos, plus material grade, quantity, annual volume, tolerance requirement, machining areas, surface finish, application and inspection requirements.

MOQ can be flexible depending on tooling, material grade, part size and machining scope. As a practical starting point, small-batch projects can be reviewed case by case, and sample timing is typically discussed around a 3-4 week window after drawing confirmation.

We can review common 2D drawing files such as PDF, DWG and DXF, and common 3D model files such as STP, STEP, IGES and OBJ. For large RFQ packages, please confirm the final file format with our team.

Common project discussions include 304, 304L, 316, 316L, CF8, CF8M, 410, 416, 17-4PH, 2205 duplex and selected high-temperature alloys. The final grade should be confirmed from the drawing standard and working environment.

304 or CF8 is often considered for general corrosion-resistant parts. 316, 316L or CF8M is usually reviewed when chloride exposure, marine use or stronger corrosion resistance is required.

Silica sol investment casting is usually preferred for complex, detailed and higher surface-quality components. Water glass, DLP wax, vacuum casting or sand casting can be reviewed when cost, size, prototype or production requirements make them practical.

Yes. Many parts require machining for sealing surfaces, mounting faces, holes, threads and assembly areas. Machining requirements should be included in the RFQ and inspection plan.

Depending on project requirements, inspection can include spectrometer chemical composition analysis, CMM dimensional inspection, mechanical property testing, destructive testing when required, NDT and final shipment review. Material certificates and dimensional reports can be prepared when requested.

If a buyer reports a quality issue, the process should include photo or report review, batch traceability check, root cause analysis and corrective action. Rework, replacement or credit terms should follow the confirmed purchase agreement and inspection standard.

Yes. Prototype work can help verify design, assembly, surface finish and material behavior before repeat production. DLP printed wax patterns or prototype tooling can be reviewed depending on the part.
