Here is an excerpt from the Lost Foam Metal Casting section page on Metal Casting Zone:

“Foam Shaping: The original foam pattern of the Polystyrene is generally molded or carved.

Carving Polystyrene: The formed foam or polystyrene is then carved using traditional carving tools or the new-age hot-wire cutting tools. It can also be sanded easily.

Injecting Polystyrene in a Mold: Polystyrene contains pentane as a blowing agent and is commonly used for beads. The beads are pre-extended, stabilized and then blown into the mold to form pattern sections. A steam cycle forces the beads to expand fully, after this the fuse together and then it undergoes an in-mold cooling cycle. The final shape if very complex, then it is molded in sections. A cluster is formed by aging and gluing together the shaped foam sections.  

Preparing Final Mold (Investment) for Casting: Gates and Raisers are generally attached to the pattern, they are also the part of the casting as this helps reduce the shrinkage. Pouring, dipping or spraying are the different methods used for coating the foam cluster with ceramic investment. The reason for this coating is that it forms a barrier and helps to prevent the molten metal to penetrate or cause sand erosion while pouring. Structural integrity of the casting is protected thanks to the coating.”
