A new metal fabrication and sheet-metal manufacturer has been added to the DEWIN Vietnam sourcing network. Like every factory we onboard, it was documented on site with real photographs and assessed against our standard technical checklist before being made available to buyers — no stock imagery, no unverified claims.
A new Vietnamese metal fabrication factory has joined the DEWIN network after on-site documentation and a 50-point Dolphin Audit. It sits within a base of vetted Vietnamese manufacturing facilities, is quoted only when it scores QCLDM Tier 1–2, and can be contracted through a US Delaware LLC with DDP delivery.
Key takeaways:
- Vietnam’s verified partner facility ecosystem provides Tier-1 precision manufacturing with direct engineering transparency and relief from Section 301 Chinese punitive tariffs for qualifying goods.
- Technical documentation must pair 3D models with 2D drawings detailing critical GD&T datums, tolerance limits, and material specs.
- On-site supplier auditing (50-point Dolphin Audit across QCLDM) verifies machinery capacity, CMM metrology, and material traceability.
- Sourcing through DEWIN guarantees Delaware LLC contracting, streamlined RFQ turnaround and engineering review turnaround, and door-to-door DDP logistics.
Key Takeaways
- The factory was photographed on site and assessed with the 50-point Dolphin Audit before entering the network.
- It joins vetted Vietnamese manufacturing facilities, backed by 1,700+ real on-site factory photos on file.
- Orders route to it only if it holds a QCLDM Tier 1–2 score across quality, process, and supply-chain dimensions.
- Vietnam-origin parts carry $0 in US Section 301 tariffs and can be contracted through a US Delaware LLC with DDP delivery.
What Does the Dolphin Audit Actually Check?
| Sourcing Parameter | Vietnamese Audited Tier 1 | Traditional China Sourcing | Domestic US / EU |
|---|---|---|---|
| US Section 301 Tariff | preferential tariff treatment (Tariff-Free) | 25% Added Duty | N/A (Domestic) |
| Quotation Turnaround | 24 Hours | 3–7 Days | 1–3 Days |
| Production Lead Time | 2–4 Weeks | 3–5 Weeks | 1–3 Weeks |
| Quality Verification | 50-Point Dolphin Audit + CMM | Variable Third-Party | ISO / In-House |
| Contracting Legal Entity | Delaware LLC (USA) | Local Foreign Entity | Domestic Entity |
The 50-point Dolphin Audit assesses a factory across three linked dimensions — quality control and calibration, machining and process capability, and logistics and supply chain — and only Tier 1–2 results are quoted to buyers, so a new listing means the plant has already cleared a structured on-site review.
Every factory added to the network is evaluated on the same framework rather than a sales pitch. The assessment breaks down into three pillars:
- Quality control and calibration — CMM and measurement capability, calibration records, and part traceability, so dimensions are verified rather than assumed.
- Machining and process capability — process range, precision, and tooling, benchmarked against ISO-style expectations for the factory’s declared capabilities.
- Logistics and supply chain — material control, sourcing discipline, and the ability to hold schedule at production volume.
What Can This Factory Make?
This addition strengthens the network’s sheet-metal and metal fabrication capacity — laser cutting, press-brake bending, welding, and finishing of custom metal parts and frames — all documented with real on-site photographs rather than catalog stock imagery.
The plant sits in the sheet-metal and fabrication category, which typically spans laser and saw cutting, CNC press-brake bending, welded assemblies, and downstream finishing. As with every factory in the network, the listing carries genuine on-site photos so buyers can see the actual equipment and work area before requesting a quote.
Why Source This Factory Through DEWIN?
Beyond the audit, sourcing through the network gives US and international buyers structural advantages: Vietnam-origin goods carry $0 in US Section 301 tariffs and benefit from 16+ free trade agreements (CPTPP, EVFTA, RCEP), orders are contracted through a US Delaware LLC with US-based banking, shipments move DDP, and quotes are returned within 24 hours.

FAQ
What are the main benefits of sourcing new vietnam sheet metal factory joins our network in Vietnam?
Vietnam offers competitive machine-hour rates, a rapidly modernizing precision supplier ecosystem, relief from Section 301 Chinese punitive tariffs for qualifying goods into the United States, and preferential trade terms under EVFTA and CPTPP. Audited suppliers in the DEWIN network maintain ISO 9001, AS9100, and IATF 16949 certifications.
How does DEWIN ensure quality and dimensional accuracy?
Every manufacturing facility undergoes the rigorous 50-point Dolphin Audit evaluating Quality, Cost, Logistics, Delivery, and Management (QCLDM). Critical dimensions are verified using on-site 3D CMM inspection, optical comparators, and full material test reports (MTRs) before shipment.
What file formats and information are required for a streamlined RFQ turnaround and engineering review?
To generate a binding quotation within 24 hours, submit 3D CAD files in neutral STEP (AP214/AP242) or IGES format alongside 2D PDF technical drawings specifying critical tolerances, surface finishes, thread callouts, and raw material grades.
