Aluminum Sand Casting: An Overview #
Sand casting is a widely used process for aluminum components, with over 70% of global metal castings produced using this method. RONG-FENG is recognized as a leading aluminum alloy sand casting foundry in Taiwan, offering both Green Sand Casting and Air Set Casting techniques.
Why Choose Sand Casting? #
- Up to 95% of sand is recycled and reused, reducing costs and environmental impact
- Cost-effective for small production runs compared to other casting methods
- Flexible mold material options: wood, aluminum, steel, or polystyrene
- Suitable for casting complex and large parts
Air Set Casting, in particular, is ideal for large, intricate castings. Chemically bonded dry sand molds provide a superior surface finish and can accommodate demanding sizes and geometries in a single casting.
Sand Casting Process #
- Mechanically mix sand with binder and resin to form a hardened mold
- Create two-part molds (Cope and Drag) by filling molding boxes with sand
- Remove patterns and assemble the mold halves
- Pour high-quality molten aluminum alloy into the mold
- Allow the metal to cool and solidify
- Break away the sand and process the casting as required
Advantages of Air Set Casting #
- Designed for larger, heavier, and more complex castings
- Delivers excellent as-cast surface finishes for high aesthetic requirements
- Supports a wide range of aluminum alloys, including A356, A380, and A413.2
