Overflows

Overflows are cavities and passages in the die which act as vents for air to escape and cavities for excess metal flow.

Overflows reduce porosity and promote complete metal fill into the far sections of the cavity.

Two overflow designs were considered for the fan housing with the center shot gate.

--- Option A -- Six overflows around the perimeter of the rim
--- Option B -- Twelve overflows around the perimeter of the rim

Choose the overflow design
(Option A or Option B)
that will provide complete fill of the outer rim.

Option A - Six Overflows

Option B - Twelve Overflows
