Steam
Chamber:
EPS
shape
molding
machines
typically
consist
of
a
steam
chamber.
The
pre-expanded
EPS
beads,
which
are
soft
and
pliable,
are
fed
into
the
machine
through
the
steam
chamber.
Molding
Chamber:
Once
inside
the
machine,
the
pre-expanded
EPS
beads
are
transferred
to
the
molding
chamber.
The
molding
chamber
contains
a
mold
or
tooling
that
defines
the
desired
shape
and
size
of
the
final
EPS
foam
product.
The
expanded
beads
are
placed
into
the
mold
cavity.
Closing
and
Pressing:
After
the
beads
are
in
the
mold
cavity,
the
molding
chamber
is
closed,
and
pressure
is
applied
to
compress
the
beads.
This
compression
allows
the
beads
to
fuse
together,
forming
a
solid
and
uniform
structure.
