The Capabilities
of a Nation.
From 5-axis CNC to 3,000-ton die casting. Explore the processes supported by our network of 178+ audited factories. No estimates, no marketing spec-sheets—just the verified machinery on the ground in Vietnam.
How We Verify Every Factory
Equipment brands, machine counts, and inspection capability are verified in person by our on-site team — not taken from factory brochures or online profiles.
QCLDM Scoring — Factory Tier Classification
| Tier | Score | Rating | Suitable For |
|---|---|---|---|
| Tier 1 | 90–100/100 | ⭐⭐⭐ | Top-rated factories. Recommended for high-precision, high-volume, or regulated programs (automotive, medical, aerospace). |
| Tier 2 | 80–89/100 | ⭐⭐ | Solid factories. Recommended for standard commercial programs with professional quality expectations. |
| Tier 3 | 70–79/100 | ⭐ | Developing factories. May be suitable for simple parts with close DEWIN supervision. Improvement plan in progress. |
| Probationary | 60–69 or critical fail | ⚠️ | Not currently recommended for active programs. Under review or improvement plan. |
DEWIN recommends Tier 1 and Tier 2 factories for new programs. Tier 3 available with additional supervision.
Vietnam's FTA Network — Every Process Benefits
Parts manufactured in Vietnam with proper Certificate of Origin can access preferential tariff rates in 60+ countries through Vietnam's active FTAs. DEWIN manages COO documentation for every shipment.
CNC Machining
Multi-axis milling, turning, Swiss-type lathes, wire EDM. From single prototypes to 100K+ production runs. Vietnam's precision machining base includes Japanese-managed factories with 5S culture, in-house CMM and VMM inspection equipment.
Sheet Metal Fabrication
Fiber laser cutting up to 25mm, CNC press brakes, robotic welding, powder coating, e-coating. CNC fiber laser cutting verified vs. plasma/manual shear — non-contact process yields precision kerf and eliminates heat distortion on thin gauges.
Aluminum Die Casting
High-pressure, gravity, and low-pressure die casting. Aluminum ADC12/A380, zinc Zamak alloys, 80T–3,000T machines. Cold-chamber machine type verified to confirm suitability for aluminum alloys (vs. hot-chamber zinc).
Plastic Injection Molding
Thermoplastic and thermoset molding from 50T to 2,500T. In-house mold design, EDM, and secondary operations. Color comparison machine (colorimetry/delta-E) verified at select factories for color-critical programs.
Stamping & Pressing
Progressive die stamping, deep drawing, fine blanking. Single-hit presses to 600 SPM high-speed lines. Die maintenance logs and press tonnage records reviewed during Dolphin audit for production consistency assurance.
Precision & Investment Casting
Lost wax casting for complex geometries. Stainless steel, carbon steel, alloy steel. In-house wax injection — the dimensional accuracy foundation verified on-site. Hardness tester for alloy grade and heat treatment confirmation.
Iron & Sand Casting
Sand casting and gravity casting for larger, heavier parts. Gray iron, ductile iron, and steel. In-house CNC machining and finishing available. Spectrometer and metallurgical analysis for material grade verification.
Surface Finishing
Anodizing (Type II/III), electroplating, powder coating, e-coating, painting, passivation, and polishing. Finish type, tank concentration, and coating thickness verified during Dolphin audit — not self-reported from finish spec sheets.
Plastic & Rubber Parts
Rubber molding, O-rings, seals, gaskets, silicone parts, TPU/TPE overmolding, and custom compounds. Shore A hardness tester verified at select factories for compliance with buyer-specified material grade requirements.
Certifications Verified Across Our Network
Every factory certificate is physically verified during the Dolphin Audit. We check the IAF-accredited registrar, scope of certification, expiry date, and active shop-floor compliance.

Frequently Asked Questions
DEWIN's Vietnam network supports 10+ manufacturing processes including CNC machining (59 factories), sheet metal fabrication (22 factories), aluminum die casting (24 factories), plastic injection molding (30 factories), stamping (13 factories), investment casting, iron/sand casting, surface finishing, plastic/rubber parts, and assembly. All factories are audited on-site using the 50-point Dolphin Audit.
The Dolphin Audit is DEWIN's proprietary 50-point factory assessment covering 5 pillars of 10 points each: Facility & Safety, Equipment & Capacity, Quality Systems, Workforce & Management, and Export Compliance. Our team physically visits the factory, photographs all major equipment, verifies certificates against registrar databases, and scores each criterion. Each factory receives a QCLDM score out of 100: Tier 1 (90–100) preferred suppliers, Tier 2 (80–89) approved suppliers, Tier 3 (70–79) conditional approval; factories scoring below 60 are not listed.
Vietnam has 16+ active FTAs. Key agreements include: CPTPP (Canada, Australia, Japan, Mexico, New Zealand, Singapore and more), EVFTA (EU 27 countries), RCEP (ASEAN + China + Japan + Korea + Australia + New Zealand), and UKVFTA (United Kingdom). DEWIN manages Certificate of Origin documentation (VCCI Form B and FTA-specific CO forms) for every shipment to maximize FTA benefit.
All equipment specifications are verified in person by DEWIN's on-site audit team during the Dolphin Audit Pillar 2 (Equipment & Capacity). Our team photographs machines, records make/model/year, verifies spindle count and tonnage, and checks maintenance logs. We do not rely on factory brochures or self-reported spec sheets. Real photos from our audits are shared with qualified buyers.
Across DEWIN's factory network: 80+ factories hold ISO 9001:2015, 12 hold IATF 16949 (automotive), 6 hold ISO 13485 (medical devices), 35+ hold ISO 14001 (environmental), 3 hold AS9100D (aerospace), and 100+ comply with RoHS/REACH. All certifications are physically verified during Dolphin Audit Pillar 3 — we confirm the registrar, scope, expiry, and practical QMS implementation.
