FAQs About Our Manufacturing Services
How do I start an order?
Just provide your technical drawings (2D/3D CAD) by email or upload, our engineering team will evaluate the manufacturability and provide you a detail quote and feasibilityassessment.
When can you deliver the order after payment?
Our standard lead time are 2-3 working days for samples and 5–7 working days for bulk order, subject to order volume and part complexity.
How does RPD protect data and intellectual property? Can you assure me that my design will remain confidential?
RPD adhere to strict Intellectual Property (IP) protection protocols. We are fully prepared to sign a Non-Disclosure Agreement (NDA) before receiving any sensitive data to ensure your proprietary designs remain secure.
What is your quality control system?
We operate under a rigorous Quality Management System (QMS) aligned with ISO standards. Our 5 Steps QC process is including IQC (Incoming Quality Control) , FQC (Final Quality Control) , OQC (Outgoing Quality Control) for routine production.
QE (Quality Engineering) / CAPA (Corrective and Preventive Actions) implemented throughout the entire product lifecycle, especially during the post-sale stage, to drive continuous improvement. Simply speaking 100% inspection before shipment to ensure zero defects.
What kind of quality assurance or warranty do you offer on orders?
One of the reasons engineers purchase from RPD is that we take on all the risks for you. We guarantee you’ll love what you get. Not happy with it? We’ll either redo it or give you a full refund. Your purchase is completely risk-free.
How to work with RPD? What's the order process?
The standard steps are: Request Quote -> Order Confirmation -> Pay Deposit -> Manufacture -> Order Ready & Inspection -> Balance -> Ship & Track -> Order Arrival. Don’t worry, upon ordering, you will be assigned a senior project manager. You will get update from my team via email or phone.
