← TechnologyWhich risk increases when a die-casting mold's venting system fails?
A)Increased porosity in the casting✓
B)Elevated alloying element segregation
C)Reduced material melting temperature
D)Premature die component plastic deformation
💡 Explanation
Increased porosity occurs because inadequate venting traps gases during solidification. This prevents gases from escaping via efficient degassing, therefore leading to air pockets and a weaker casting, rather than altered composition or die damage.
