Based on the rheology and molding sand micro deformation, elastic modulus of molding sand was measured and investigated with the intelligent molding sand multi property tester developed by ourselves.

Casting quality and rejection rate are remarkably affected by the quality and property of molding sand, in the process of clay sand green mold casting.

By taking EPS emulsion as main raw material, a new casting binder of non-coal molding sand was developed. EPS water-borne property by modification is fine, and available for the casting binder.
