← TechnologyWhich outcome results when casting molds experience excessive heating?
A)Increased porosity in cast part✓
B)Improved surface finish quality
C)Reduced metal solidification rate
D)Enhanced mold material strength
💡 Explanation
Increased heating of casting molds accelerates reactions releasing gases, resulting in increased porosity because gas solubility decreases. This is caused by reduced cooling, therefore increased porosity occurs, rather than improved surface finish or greater metal solidification, which need mold stability.
