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.
Runner 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.
