Aluminum Sand and Gravity Casting in Vietnam: Process and Benefits
Table of Contents
Introduction
Aluminum sand and gravity casting in Vietnam is becoming a preferred choice for industries that require large, durable, and custom aluminum components. Unlike high-pressure die casting, these methods use slower but more flexible processes, making them ideal for low-to-medium production runs and complex designs. As a result, global buyers in automotive, construction, and machinery turn to Vietnam for high-quality sand and gravity cast parts at competitive prices.

What is Aluminum Sand Casting?
Aluminum sand casting forms parts by pouring molten aluminum into sand molds. Workers create a cavity that matches the final shape, then allow the aluminum to cool and solidify. After cooling, they break the mold to release the part.
Advantages of aluminum sand casting include:
- Flexibility for large or complex shapes.
- Cost-effective tooling for prototypes and short runs.
- Compatibility with many aluminum alloys.
Therefore, aluminum sand casting remains one of the most practical options for heavy and custom parts.
What is Aluminum Gravity Casting?
Aluminum gravity casting, also called permanent mold casting, uses reusable steel or iron molds. Molten aluminum fills the cavity under the force of gravity rather than external pressure.
Advantages of aluminum gravity casting include:
- Better surface finish than sand casting.
- Stronger mechanical properties with fewer defects.
- Medium-volume efficiency thanks to reusable molds.
Because of these features, aluminum gravity casting works well for parts that need higher precision and tighter tolerances.
Applications of Aluminum Sand and Gravity Casting
Both casting methods support a wide variety of industries that require strength and reliability:
- Automotive – Engine housings, brackets, and suspension components.
- Construction – Building fittings, facade systems, and structural parts.
- Industrial machinery – Pumps, valves, and heavy-duty equipment parts.
- Marine – Propellers and corrosion-resistant components.
Moreover, aluminum sand and gravity casting allows manufacturers to serve both prototype development and large industrial projects.
