What Buyers Say After Seeing Inside Our Factories

"Seeing inside the factory — the actual machines, inspection area, and the audit scorecard — gave me more confidence than a hundred Alibaba profiles ever could."

Francisco García Quintana 🇬🇧
MD, LAROME

"The virtual tour was the convincer. Real photos of the CMM machine, the finished parts storage, the 5S board — you can't fake that. I knew this was a serious factory."

Factory Tour FAQ

What is included in a virtual factory tour?
A Dewin virtual factory tour includes a curated selection of our on-site factory photos and videos (1,700+ real images and 659+ video clips), a walkthrough of the factory's 50-point Dolphin Audit QCLDM scorecard, equipment highlights relevant to your parts, and a live Q&A with our sourcing team. You see the actual factory floor — not stock photos.
Can I physically visit a factory in Vietnam?
Yes. Dewin can arrange on-site factory visits for qualified buyers. Our on-the-ground team in Vietnam will accompany you, pre-arrange with the factory, and translate as needed. We typically schedule in-person visits 2–3 weeks in advance. Contact us to discuss a Vietnam factory visit trip.
What does the Dolphin Audit score mean for the factories I'll see?
Every factory in our network has been physically audited using our 50-point Dolphin Audit framework across 5 pillars: Facility & Safety, Equipment & Capacity, Quality Systems, Workforce & Management, and Export Compliance. Factories are scored 0–100 and assigned a QCLDM tier (Tier 1: 85+, Tier 2: 70–84, Tier 3: 55–69). Only Tier 1 and Tier 2 factories are featured in our active sourcing network.
How quickly can I get factory options after requesting a tour?
For standard processes (CNC machining, die casting, sheet metal, injection molding, stamping, investment casting), we can typically present a shortlist of 2–3 audited, matched factories within 3–5 business days of receiving your part specifications. The factory tour request starts the conversation; drawings close it.
Do I need to speak Vietnamese to work with your factory network?
No. All factory communication, technical document translation, quality inspection reports, and audit documentation are handled by Dewin's bilingual on-the-ground team. Your single point of contact at Dewin manages everything in English on your behalf.
