Lost Foam Process is similar to Lost Wax (Investment casting) process.
First a foam pattern is molded using Expandable Polystyrene (EPS) or co-polymer which is an exact replica of the desired casting. Runners and risers are attached by glue to the foam pattern and a cluster is made of one or more number of foams. The cluster is then coated with a permeable refractory slurry coating in a homogenous bath by dipping.
Lost Foam Process has following advantages over conventional Green Sand Process.
Closer tolerance on dimensions. No mismatch. Suitable for CNC / SPMs operations by eliminating pre-machining.
It is a Coreless process hence total elimination of Fins and Flashes on the casting.
