The ability of molding sand to move between pattern and sand under the
action of external force or gravity is called flow ability. The mold
cavity with uniform compactness, clear contour, smooth surface and
accurate size can be obtained by the sand with good fluidity, which is
beneficial to prevent mechanical sand sticking, reduce sand tightening
time and improve productivity.

The sand with large particle size and small angle coefficient has good fluidity.
The properties and amount of binder also have a great influence on the
fluidity. It has been proved that the fluidity of Ca bentonite sand is
the best, that of common clay is a little less, and that of Na bentonite
is the worst. When the amount of original sand is fi
