Basic Steps in Aluminum Sand Casting Process
A pattern is built from your print or model. The pattern is a positive shape of your part.
A sand mold is made using the pattern. The sand mold is a negative.
If your part is a solid aluminum sand casting, the pattern is all that’s required. If your casting is hollow, a separate component called a core must be used. Cores are the shape of the inside of your part. A second tool component will be required, called a core box. Sand is put into the core box and cured to produce a core.
The core is set into the mold before it is closed. Metal is poured into the mold traveling through a “gating” system and into the void left by the pattern and core.
After the metal solidifies the mold is “dumped.” Your aluminum sand castings still attached to the gating system are pulled from the sand.
The core is vibrated out of the aluminum sand casting and the casting is cut off of the gating.
The aluminum sand casting then needs ground. The gating contacts and any excess metal fins are removed from the casting leaving only the shape you required.
The castings are then blasted and inspected and made ready for shipment.
