FAQ

Q1. What is a professional rapid prototyping service?

It is a project-based service that converts a drawing, CAD model, sample or concept into a functional prototype for fit checks, engineering review, design validation and early testing before larger production.

Q2. Do you provide OEM ODM CNC machining service?

Yes. OEM production can follow an approved drawing and revision. ODM projects can start from a sample, product concept or functional requirement, followed by engineering review and a manufacturing proposal.

Q3. Do you support CNC milling, CNC turning and CNC 5-axis machining?

The image labels all three process directions: CNC Milling, CNC Turning and CNC 5-axis. The final process route depends on the part geometry, material, access, tolerance and project requirements.

Q4. Can you make stainless steel and aluminum prototype parts?

Stainless steel and aluminum can be reviewed for prototype parts. Exact grades, material condition, surface treatment and inspection requirements should be specified before production.

Q5. What types of precision customized metal parts can you make?

The visible range includes housings, brackets, flanges, sleeves, plates, threaded fittings, shafts, rings, multi-hole blocks, curved components and impeller-like parts. Final feasibility depends on the approved design.

Q6. Can you produce one prototype or a small batch?

One-piece prototypes, sample batches and low-volume production can be discussed according to setup, material, inspection, finishing and packaging requirements.

Q7. Can you work from a physical sample?

Yes. A sample can support replacement-part development, design review or reverse-engineering discussion. For repeat production, a dimensioned drawing or CAD file is recommended.

Q8. When is CNC 5-axis machining useful?

It is useful for angled faces, curved surfaces, deep features and components that need access from multiple directions. The actual machine route should be confirmed after geometry review.

Q9. Can surface color and finish be customized?

Suitable finish options can be discussed according to the material. Anodizing is generally associated with suitable aluminum grades; color, alloy and finish requirements must be confirmed.

Q10. Can you machine complex cavities and thin ribs?

Complex cavities and ribs can be reviewed. The drawing should define wall thickness, internal radius, depth, access, datum and functional requirements so the process can be evaluated accurately.
