How We Work

From Drawing Review to Final Inspection

OUJI helps reduce project risk by reviewing technical requirements, confirming manufacturing processes, coordinating suppliers, and checking parts before shipment.

01

Drawing Review

We review drawings, materials, tolerances, surface requirements, quantities, and project notes before quotation.

02

Process Confirmation

We confirm suitable processes such as CNC milling, turning, fabrication, 3D printing, finishing, or combined manufacturing routes.

03

Manufacturing Arrangement

We coordinate production based on part geometry, batch size, material, tolerance level, and delivery requirements.

04

In-Process Communication

For critical projects, we help clarify technical questions and keep the project moving during manufacturing.

05

Final Inspection

Parts are checked against drawings, surface requirements, and key dimensions before packing and delivery.

06

Packing & Delivery

We support proper packing, export communication, and shipment preparation for global customers.

Quality Support

Quality Support for Custom Precision Parts

Custom parts often involve small quantities, changing requirements, tight tolerances, and multiple processes. OUJI focuses on reducing quality risk through drawing review, supplier coordination, and final inspection support.

FAQ

Frequently Asked Questions

Common questions about OUJI custom precision parts manufacturing, quotation requirements, and project support.

What files should I send for a CNC machining quote?

Please send 2D drawings, 3D CAD files, material requirements, tolerances, surface finishing notes, quantity, and expected delivery time. Photos or samples can also help if the part is being replaced or improved.

Can OUJI support machining and surface finishing together?

Yes. OUJI can coordinate CNC machining with anodizing, plating, passivation, polishing, sandblasting, coating, heat treatment, and inspection requirements when needed.

Do you support prototype and low-volume production?

Yes. OUJI supports prototype parts, engineering samples, pilot runs, and low-volume production where flexible communication and process review are important.

How fast can I receive a quote?

For clear drawings and qualified RFQs, OUJI aims to review the request within 12 hours. Complex projects involving multiple processes, special materials, or finishing requirements may need additional confirmation.

How does OUJI reduce quality risks before shipment?

OUJI reviews drawings, confirms key requirements, checks critical dimensions and surface requirements, and supports final inspection before packing and shipment.
