Thailand has a well-established manufacturing base for automotive, motorcycle, electronics, agricultural machinery, and industrial components. Aluminum die casting is an important part of this supply chain, supported by both Thai manufacturers and international groups operating production facilities in the country.
For buyers, however, choosing a supplier involves more than finding a factory with die casting machines. Tooling capability, machine tonnage, CNC machining, finishing, inspection, production volume, and industry experience can all affect project suitability.
This guide introduces 10 aluminum die casting manufacturers operating in Thailand. The companies are not ranked in a specific order.
Looking Beyond Thailand? Consider Yongzhu Casting in China
Location: Zhejiang, China
Main Capabilities: Aluminum die casting, mold making, CNC machining, surface finishing
Best For: Custom parts manufactured from customer drawings
Yongzhu Casting is based in Zhejiang, China, not Thailand. We include our company separately for buyers who are comparing die casting suppliers across Asia rather than requiring Thailand-origin production.
Since 2004, Yongzhu has focused on custom aluminum die cast parts produced from customer drawings. Our workflow can cover drawing review, tooling, high-pressure die casting, CNC machining, finishing, and inspection for industrial applications.
If production does not have to be located specifically in Thailand, comparing both Thai and Chinese suppliers can provide more options for tooling, production volume, secondary machining, and project cost.

How We Selected These Manufacturers
The companies were selected using publicly available information showing aluminum die casting production or closely integrated casting operations in Thailand.
We considered casting capability, machining and secondary operations, industries served, manufacturing presence in Thailand, and available company information. This is a sourcing reference rather than an absolute ranking, and buyers should confirm current equipment and production capacity directly with each supplier.

9. CSP Casting (Thailand) Co., Ltd.
CSP manufactures aluminum and zinc die castings as well as gravity-cast products. Thailand’s Board of Investment supplier database lists capabilities including aluminum die casting, machining, and friction stir welding, with automotive and electrical/electronics among its main markets.
10. Siam Inter Mold Co., Ltd.
Siam Inter Mold provides high-pressure die casting for automotive, electronics, agricultural machinery, and home-appliance applications. The company lists die casting machines from 350 to 650 tons together with finishing and shot-blasting processes.
Casting Processes Buyers May Encounter in Thailand
Buyers searching for casting suppliers in Thailand often compare several processes. These processes should not be treated as interchangeable; the best choice depends on part design, alloy, required properties, quantity, and tooling budget.
High-Pressure Die Casting
High-pressure die casting is particularly suitable for medium- to high-volume aluminum parts with relatively complex geometry and repeatable dimensions. Thailand has a significant HPDC base, especially around automotive manufacturing.
Gravity Casting
Gravity casting uses gravity rather than high injection pressure to fill the mold. It can be useful for thicker sections, different production volumes, and applications where the requirements differ from conventional HPDC. Some Thai suppliers, including Sanko and CSP, publicly list gravity casting alongside die casting.
Sand Casting
Sand casting is a different process from die casting and is generally considered when production quantities, component size, or tooling requirements do not justify a permanent high-pressure die casting tool.
Investment Casting
Investment casting is another separate manufacturing process, typically selected for complex precision components and materials or geometries that may not suit aluminum HPDC.
If a drawing is already available, the manufacturing process should normally be selected from the technical requirements rather than from the process name alone.
How to Choose a Die Casting Supplier in Thailand
Start with the part requirements before comparing company size or quoted unit price.
A supplier should be able to confirm whether its machine tonnage, tooling capability, alloy experience, and normal production volume match your component. If machining is required, determine whether critical operations are completed in-house and how dimensions are controlled after casting.
For an RFQ, provide:
- 2D drawings and 3D models
- Required aluminum alloy
- Estimated annual volume
- Critical tolerances
- CNC machining requirements
- Surface finishing
- Inspection or testing requirements
For large or long-term programs, tooling maintenance, sample approval, quality documentation, engineering communication, and production capacity should also be evaluated.
Thailand vs. China for Aluminum Die Casting Sourcing
Thailand and China can both support aluminum die casting projects, but the better sourcing location depends on the project.
Thailand may be attractive when a buyer specifically needs Thai production, is building an ASEAN supply chain, or already has assembly and purchasing operations in Southeast Asia.
China offers a much larger manufacturing ecosystem covering tooling, die casting, machining, finishing, and related processes. For projects without a strict Thailand-origin requirement, comparing suitable suppliers in both countries can help buyers evaluate manufacturing capability, engineering support, tooling cost, lead time, and total delivered cost.
This is why Yongzhu Casting appears separately in this article: we are not a Thailand manufacturer, but we can be evaluated as a China-based alternative for custom aluminum die casting projects.
Frequently Asked Questions
Does Thailand have aluminum die casting manufacturers?
Yes. Thailand has a substantial aluminum die casting industry, particularly around automotive and industrial manufacturing. Both Thai-owned companies and international manufacturing groups operate die casting facilities in the country.
Is high-pressure aluminum die casting available in Thailand?
Yes. Many Thai manufacturers operate high-pressure die casting equipment for automotive, electronics, machinery, and other industrial components. Machine tonnage and available secondary processes vary by supplier.
What should I send to a Thailand die casting manufacturer for a quotation?
Send a 2D drawing and preferably a 3D model, together with the required alloy, estimated annual quantity, tolerances, machining requirements, surface finish, and inspection requirements.
Are gravity casting and die casting the same process?
No. High-pressure die casting injects molten metal into a steel die under pressure, while gravity casting fills the mold primarily through gravity. The appropriate process depends on component design, quantity, mechanical requirements, and other project factors.
Can I source aluminum die cast parts from China instead of Thailand?
Yes, if the project does not require Thailand-origin production. Buyers can compare suppliers in both countries based on engineering capability, tooling, production volume, quality control, machining, lead time, and total project cost.
Need Custom Aluminum Die Cast Parts?
If your project is not restricted to production in Thailand, Yongzhu Casting in Zhejiang, China can also review your requirements.
