Die Casting in Vietnam: Landscape, Products & Key Vendors
Die casting is one of the most cost-effective processes for producing complex metal components at volume. Vietnam's die casting industry has grown significantly — but capability varies considerably across vendors.
Vietnam has a functioning and growing die casting sector covering both aluminium and zinc alloys. The key is knowing which factories are genuine precision producers, which materials are readily available, and which vendors can support export-quality standards.
// Aluminium vs Zinc
The Two Main Die Casting Alloy Families
Die casting in Vietnam centres on two material families: aluminium alloys and zinc alloys (Zamak). Each has distinct advantages, process requirements, and a different vendor ecosystem in Vietnam.
Aluminium Die Casting
- Common alloys
- ADC12, A380, A360
- Casting temp
- ~650–700°C
- Typical wall
- 1.5–4mm
- Part weight
- Up to ~10kg
- Vietnam supply
- Strong
Zinc (Zamak) Die Casting
- Common grades
- Zamak 3, 5, 7, 2
- Casting temp
- ~385–400°C
- Typical wall
- 0.6–3mm
- Part weight
- Grams to ~2kg
- Vietnam supply
- Zamak 3 ✓ / Zamak 2 limited
// What gets made
Products Made by Die Casting in Vietnam
Aluminium die casting — used where lightweight, strength, and tight tolerances matter:

Zinc (Zamak) die casting — used where fine detail, thin walls, and surface finish matter:
Zinc / Zamak · Hardware & Locks
Lock bodies, door handles, hinges, cabinet hardware, padlock components
Zinc / Zamak · Consumer Goods
Belt buckles, decorative fittings, zippers, eyewear frames, watch cases

Zamak Grades in Vietnam: Know What You Are Specifying
Not all Zamak grades are equal, and not all are available in Vietnam. This matters significantly when writing your specification.
| Grade | Key Property | Vietnam Availability | Notes |
|---|---|---|---|
| Zamak 3 | Balanced properties, most common | Readily available | Default choice for most hardware and consumer applications |
| Zamak 5 | Higher strength, better creep resistance | Available | Used where slightly higher mechanical demands apply |
| Zamak 7 | High fluidity, thin-wall capability | Limited | Fewer vendors stock this; confirm before specifying |
| Zamak 2 | Highest hardness, highest copper content | Scarce | Not stocked by most Vietnamese die casters. Dynacast Binh Minh is the primary option. |
// Design tip
Grade flexibility on the factory floor
Design tip: If your application can tolerate Zamak 3 instead of Zamak 2, your vendor pool in Vietnam increases significantly. Raise this with your engineering team early. The mechanical property difference is real but often not critical for many hardware and consumer applications.

What to Confirm Before You Send an RFQ
Die casting in Vietnam is mature enough to support most standard aluminium and Zamak 3 applications. Before engaging vendors, confirm three things: your alloy grade and whether it is stocked locally; whether secondary operations (machining, plating, coating) are in-house or outsourced; and what annual volumes you are working toward — tooling cost amortisation becomes significant below 5,000 parts per year.
For zinc applications specifically, always state the Zamak grade explicitly — never just "zinc alloy." The grade determines your vendor pool, and assuming Zamak 3 availability when you have specced Zamak 2 is a common and expensive sourcing mistake.
