Your designs are safe with us.
Shipping CAD files to a manufacturer in China is a legitimate concern. Here is exactly how we handle your intellectual property, from the moment you upload to the day we archive the file.
The NDA Process
Sign first. Files second. No exceptions.
We refuse to look at any CAD file until a mutual NDA is signed by both parties. This is non-negotiable on our side, we want it to be non-negotiable on yours too.
Request NDA before files
Email us asking for an NDA. We respond with our standard mutual NDA or sign yours unchanged.
Both parties sign first
NDA must be signed by both parties BEFORE you upload any CAD files. No exceptions.
Files enter restricted access
Signed NDAs trigger restricted access, only assigned engineers see your files. Logged and audited.
Project completes → files archive
After delivery, files are moved to encrypted cold storage and never used for any other purpose.
How we protect your files
Six layers of protection, engineered, not promised.
Encrypted file transfer
All CAD uploads pass through TLS 1.3. Files stored on Cloudflare R2 with server-side AES-256 encryption at rest.
Least-privilege access
Only the engineers actively working on your project can view your files. Access is logged with timestamp and user ID.
No third-party sharing
We never share, sell, or expose your designs to any third party, including sub-suppliers, unless you specifically authorize it in writing.
Right to deletion
Email us anytime to permanently delete your files. We confirm deletion in writing within 48 hours.
No-clone policy
We will never machine your part for anyone else, even if asked. We will never use your design to produce a competing or derivative product.
Custom NDAs welcome
Send us your NDA template and we sign it as-is. No back-and-forth, no legal redlines, your terms, our signature.

The honest version: No supplier, Chinese, American, German, or otherwise, can prove they will never have an IP incident. What we can prove is a 20-year operating history, ISO 14001 / ISO 9001 process discipline, signed NDAs on every project, and references from clients in 50+ countries who will tell you directly about their experience. If trust is built on evidence, here is ours.
Verifiable Certifications
ISO certifications you can independently verify.
Our certifications are issued by Shenzhen Zhonghuan International Certification Co., Ltd (ZHIC), recognized by the China National Certification and Accreditation Administration (CNCA). Procurement reviewers can verify authenticity by scanning the QR code on each certificate or visiting the issuing body's public registry.

Common questions
Tough questions, direct answers.
Why should I trust a Chinese manufacturer with my IP?
What happens to my files after the project ends?
Will you sign my company's NDA, or only your own?
Do you sub-contract any work that exposes our files?
How do I report a suspected IP concern?
Can I audit your facility before placing an order?
File-handling policy
How we handle your CAD files
Where files live
All uploaded files are stored on Cloudflare R2 (encrypted at rest, region: APAC). Access is limited to the engineering team assigned to your quote. Files are not replicated to any third-party service for the quoting phase.
How long we keep them
- Quote stage: retained while the quote is open, then up to 90 days after we send the quote (lets you come back and revise).
- Active order: retained for the duration of production + 12 months after delivery (covers warranty + revisions + repeat-order context).
- Completed orders: archived after 12 months, accessible to the assigned engineer for the next 24 months on request, then permanently deleted.
How to request deletion
Email redowan@gh-goldenhot.com with the order ID and we delete the file from R2 + database within 7 business days, then confirm in writing. This applies even to active orders, if you cancel, your files come off our systems on the same timeline.
What we never do
- Share files with third-party shops without your written approval (sub-tier specialty processes only, named in advance).
- Use your CAD as training data, marketing material, or case-study reference without explicit permission.
- Keep files after a deletion request fulfillment, confirmation is sent only after the data is truly gone.
