| Abstract: | The relationship between swell and shrinkage cavity / porosity defects was described, and the importance of increasing rigidity of sand mould to prevent swell and shrinkage defects was explained. It was pointed out that the strength of molding sand and compactness of sand mold is the key factors influencing the rigidity of green sand mold under normal temperature. The factors influencing the rigidity of green sand mold during pouring were analyzed. |
