← TechnologyWhich outcome occurs when tight tolerances on a cold forging die are exceeded?
A)Increased part flash formation✓
B)Reduced workpiece hardness afterward
C)Elevated die lubrication breakdown
D)Decreased material flow resistance
💡 Explanation
Increased part flash occurs when die tolerances are exceeded, because the clearance allows more material to escape during forging via **plastic deformation**. Therefore, flash increases, rather than improving material properties such as higher hardness, or reducing resistance inside the die cavity.
