Advantages of Aluminum Investment Casting
Superior Design Flexibility
Aluminum investment casting can make any part in any size, shape, or configuration. It does not matter if it is a small electronic component or a large transmission casing or clutch housing for an automotive vehicle; each part is produced with high tolerances according to design intention and requires very little finishing.
Versatility
The vast design possibilities offered by aluminum investment casting allow engineers to tap into its advantageous properties. Engineers can truly design custom and unique products that realize imaginative ideas.
High Strength
Molds used in the process will rapidly cool the molten aluminum poured into it, causing the metal to solidify without trapped gas or porosity. This will give the final product better metallurgical properties, leading to higher strength and pressure tightness.
Corrosion Resistance
Aluminum investment castings will take on an oxidized surface when exposed to air. Since the natural oxidation process allows for previously cast aluminum components to be reconstituted, successful oxidation will help to provide greater longevity for aluminum castings.
Heat Resistance and Electrical Conductivity
Aluminum’s excellent thermal and electrical conductivity makes it a preferred choice in industries like electronics, automotive, and power transmission.

The Aluminum Investment Casting Process
Pattern Creation
The process begins with the creation of a wax pattern, which is an exact replica of the part to be cast. Multiple wax patterns can be assembled into a tree-like structure to allow for the casting of multiple parts in one batch.
Assembly
The wax patterns are attached to a central wax runner system, forming a tree. This assembly will eventually allow molten aluminum to flow into each pattern.
Cooling
The mold is left to cool, allowing the aluminum to solidify and take the shape of the wax pattern.
Shell Removal
Once the aluminum has cooled and solidified, the ceramic shell is broken away, revealing the cast aluminum part. The parts are then cut from the runner system.
Shell Building
The wax assembly is repeatedly dipped into a ceramic slurry, coated with sand, and left to dry. This process is repeated several times to build a thick, strong ceramic shell around the wax assembly.
Wax Removal
The ceramic-coated assembly is placed in a kiln, where the wax is melted out, leaving a hollow ceramic shell. This step is crucial as it creates the mold cavity for the aluminum.
Casting
The ceramic mold is preheated to remove residual moisture and prepare it for the molten aluminum. Molten aluminum is then poured into the mold, filling the cavity left by the wax pattern.
Finishing
The final step involves various finishing processes, like sandblasting, machining, and heat treatment, to achieve the desired surface finish and mechanical properties.
