Vietnam's Die Casting Industry
Vietnam has become a serious contender in aluminum die casting, driven by investment from Japanese, Korean, and Taiwanese manufacturers who established operations in the country over the past 15 years. This technology transfer has created a mature domestic supply base with modern equipment and trained operators.
Vietnamese die casting factories now operate cold chamber machines from 200T to 2000T — capable of producing complex automotive, industrial, and consumer electronics components that previously could only be sourced from China or established Southeast Asian hubs like Thailand.
The cost advantage is substantial. Die casting involves both tooling (one-time) and per-piece costs, and Vietnam is competitive on both fronts. Tooling typically runs 40–50% less than China, while per-piece costs are 25–35% lower before the additional tariff savings.
Capabilities
High-Pressure Die Casting
Cold chamber machines 200T–2000T. Ideal for aluminum automotive and industrial components with complex geometries and thin walls.
Tooling Design & Fabrication
In-house tool design with Moldflow simulation. H13 and premium tool steels. Multi-slide capability for complex undercuts.
CNC Post-Machining
In-house CNC milling, drilling, and tapping for critical surfaces. Keeps the entire process under one roof.
Gravity & Low-Pressure Casting
For lower volumes and thicker-walled parts. Better mechanical properties than HPDC. Ideal for structural components.

Frequently Asked Questions
What die casting alloys do you work with?
Primarily aluminum alloys: ADC12 (A383), A380, A360, AlSi10Mg, and AlSi12. We also offer zinc die casting (Zamak 3, Zamak 5) and magnesium die casting for lightweight applications.
What's the typical tooling lead time?
Die design and fabrication: 4–6 weeks for standard complexity, 6–8 weeks for complex multi-slide tools. We use P20 and H13 tool steel with 100K–500K shot life depending on alloy and complexity.
Can you do post-machining on cast parts?
Yes — most of our die casting partners have in-house CNC departments for post-machining critical surfaces, drilling, and tapping. This keeps everything under one roof for better quality control.
What's the minimum order for die casting?
Die casting is inherently a volume process due to tooling costs. Minimum practical order is typically 500–1,000 pieces to amortize tooling. For prototyping, we recommend gravity casting or CNC machining instead.
How do you inspect cast parts?
X-ray inspection, CT scanning, CMM dimensional checks, spectrometer material verification, porosity analysis, and pressure leak testing. All available at our partner factories.
What about secondary operations?
Deburring, shot blasting, vibratory finishing, CNC machining, threading, anodizing, powder coating, plating, and assembly. Our factories handle the full value chain.
