CNC machining, sheet metal, 3D printing, and finishing for prototypes and low-volume custom parts.

We review drawings, tolerances, materials, quantities and critical requirements before production begins.
Drawing & Requirement Review
Each project is produced using the appropriate machining process, equipment and production controls.
Controlled Production
Critical dimensions, appearance and project requirements are checked and documented before shipment.
Documented Inspection
Finished parts are cleaned, protected and shipped with clear inspection and project documentation.
Packing & DocumentationFrom functional prototypes to repeat low-volume production and complex precision components, OUJI provides CNC milling, CNC turning and 5-axis machining with engineering review and documented inspection.

Functional CNC machined prototypes for design validation, assembly testing and pre-production development.
Lead time depends on part complexity, material availability and finishing requirements.
Explore Rapid CNC Prototyping
Flexible CNC production for small and repeat batches, without the cost and commitment of high-volume tooling.
