    Common Questions Before Sending an Inquiry

    If your project involves custom precision parts, drawings, surface finishing, low-volume production, or multi-process manufacturing, you can send the details and we will review them.

    Send Inquiry
    Can I send only a photo instead of a drawing?

    Yes. A drawing or 3D file is better, but you can also send a clear photo, dimensions, material, and quantity for initial review.

    What file formats can I upload?

    Common formats include STEP, STP, IGS, PDF, JPG, PNG, DWG, and ZIP files.

    Can OUJI support low-volume or prototype orders?

    Yes. OUJI supports prototypes, samples, small batches, low-volume production, and custom precision parts.

    Can you help with surface finishing?

    Yes. Depending on the part and material, we can support anodizing, plating, polishing, brushing, powder coating, passivation, and other finishing requirements.

    What information helps you quote faster?

    Drawing, quantity, material, surface finish, tolerance requirements, application background, and expected delivery schedule are all useful.
