Discuss confidentiality and any NDA requirements before sending sensitive drawings. You can begin with a non-sensitive description of the component, quantities and manufacturing needs, then agree how protected information should be shared.
Share only what the review needs
Remove unrelated personal information and files that are not needed for the enquiry. Identify the drawing revision and explain any restrictions on access or onward disclosure before sharing. A private upload setting by itself does not replace a separately agreed NDA or customer-specific handling instructions.
Understand the upload route
The website sends model and drawing files directly to private Alibaba Cloud OSS storage in Hong Kong. Enquiry information and file references are saved in the website backend. Files are not added to the public WordPress media library; authorized backend downloads use time-limited links.
Keep the enquiry reference
Save the reference shown after submission so a request can be matched to the correct project. Contact JUNCHU about a correction, withdrawal or file-handling question and provide that reference where available. Review the published privacy and project-data notice before uploading information that needs special treatment.
