Vietnam has become an increasingly relevant sourcing destination for companies looking for aluminum die casting and other precision metal manufacturing services in Asia.
The market includes Vietnamese manufacturers as well as Japanese, Taiwanese, Chinese, and other international companies operating production facilities in Vietnam. Their capabilities range from high-pressure die casting and CNC machining to tooling, surface finishing, painting, and assembly.
This guide introduces 10 aluminum die casting manufacturers with production capabilities in Vietnam. The companies are not ranked in a specific order; the purpose is to help buyers compare different manufacturing options and identify suppliers worth further evaluation.
Looking Beyond Vietnam? Consider Yongzhu Casting in China
Location: Zhejiang, China
Main Capabilities: Aluminum die casting, mold making, CNC machining, secondary processing
Production Type: Custom parts based on customer drawings
Yongzhu Casting is based in Zhejiang, China, not Vietnam. We include our company separately because some buyers searching for suppliers in Vietnam are actually comparing manufacturing options across Asia rather than requiring Vietnam-origin production.
Yongzhu supports custom aluminum casting projects from drawing review and tooling through casting, CNC machining and secondary processing. Our manufacturing capabilities serve automotive, machinery, energy equipment, lighting and other industrial applications.
If your project is not restricted to Vietnam production, you can also compare our capabilities, technical support and quotation with suppliers in Vietnam.

How We Selected These Manufacturers
The companies below were selected based on publicly available information showing aluminum die casting production or closely integrated die casting operations in Vietnam.
We considered manufacturing processes, die casting equipment, machining and secondary capabilities, location, and the types of projects each company appears equipped to support.
Because equipment, ownership and production capacity can change, buyers should confirm current specifications directly with each supplier before making a sourcing decision.

Die Casting Capabilities Available in Vietnam
Vietnamese die casting suppliers offer different combinations of casting, machining and secondary processing. Buyers should therefore evaluate the actual process needed for a specific component instead of comparing suppliers only by company size.
High-Pressure Die Casting
High-pressure die casting is widely used for medium- and high-volume aluminum components requiring repeatable dimensions and relatively complex shapes. Suppliers such as Sinchi, VPIC, ONTOPS and ALTOP publicly list HPDC equipment covering different tonnage ranges.
Gravity and Other Casting Processes
Not every aluminum component is best suited to HPDC. Depending on wall thickness, production quantity and mechanical requirements, gravity or low-pressure casting may also be considered. ONTOPS, for example, lists both high- and low-pressure casting among its processes.
CNC Machining and Secondary Operations
Many aluminum castings require machined holes, sealing surfaces, threads or assembly features after casting. Several manufacturers in this list integrate CNC machining, painting, coating or assembly with their casting operations, reducing the need to coordinate several suppliers.
How to Choose an Aluminum Die Casting Supplier in Vietnam
Start with your part rather than the supplier’s marketing materials.
Send potential manufacturers a complete drawing package and confirm whether their die casting machine range, tooling capability and normal production volume are appropriate for the component.
For machined castings, also confirm which operations are performed in-house and which are outsourced. Critical dimensions, leak requirements, surface finishing and inspection documentation should be discussed before tooling begins.
For larger projects, ask about:
- Available die casting machine tonnage
- Mold design and maintenance
- Aluminum alloys regularly processed
- CNC machining capability
- Dimensional and material inspection
- Surface finishing
- Sample approval procedures
- Expected annual production volume
- Production and export lead times
The best supplier is usually the one whose normal manufacturing capabilities fit the project—not simply the largest factory.
Vietnam vs. China for Aluminum Die Casting Sourcing
Vietnam and China can both be viable sourcing locations, but they do not necessarily serve the same procurement strategy.
A Vietnam-based supplier may be important when the buyer specifically needs production in Vietnam, is developing a regional ASEAN supply chain, or wants to diversify manufacturing locations.
For projects without a strict country-of-origin requirement, it can also make sense to compare suppliers in China. The important factors remain tooling capability, casting equipment, machining, quality control, engineering communication, production volume and total delivered cost.
Instead of choosing a country first and forcing the project to fit, buyers can compare qualified manufacturers in both markets and determine which production setup best matches the drawing and purchasing requirements.
This is also why Yongzhu Casting is shown separately in this guide: we are not a Vietnam manufacturer, but we can serve as a China-based comparison option for buyers sourcing custom aluminum cast parts in Asia.
Frequently Asked Questions
Does Vietnam have aluminum die casting manufacturers?
Yes. Vietnam has both locally operated manufacturers and overseas-invested companies producing aluminum die cast components. Available capabilities include high-pressure die casting, CNC machining, tooling, finishing and assembly.
What should I send to a Vietnam die casting supplier for a quotation?
Ideally, provide a 2D drawing and 3D CAD model together with the required aluminum alloy, annual quantity, critical tolerances, machining requirements, surface finish and any inspection or testing specifications.
Is high-pressure die casting available in Vietnam?
Yes. Several manufacturers in Vietnam operate high-pressure aluminum die casting equipment. Machine capacity varies considerably by supplier, so buyers should confirm that the available tonnage is appropriate for their component.
Can I source aluminum die cast parts from China instead of Vietnam?
Yes, provided your project does not require Vietnam-origin manufacturing. Buyers can compare suppliers in both countries based on tooling, manufacturing capability, quality requirements, lead time and total project cost.
How do I choose between different die casting manufacturers?
Compare the supplier’s normal production capabilities with your specific component. Important factors include part size, alloy, annual volume, tolerances, tooling, machining, finishing, inspection and engineering support.
Need Custom Aluminum Die Cast Parts?
If your project does not require manufacturing specifically in Vietnam, Yongzhu Casting in Zhejiang, China can also review your aluminum casting requirements.
We manufacture custom parts based on customer drawings and can support tooling, aluminum die casting, CNC machining and secondary processing.
