Flow Stoppage in the Middle Area of Flow Length Occurs at Thin Die Gap

Abstract:

In molten metal flow length tests using a spiral die with a thin gap, a non-filled region of molten metal was observed in the middle of the flow length in some test pieces. The influences of die gap, plunger speed and die temperature on the position and length of the non-filled region were investigated. Both the die gap and molten metal speed significantly affected the occurrence, position and length of non-filled region. The phenomenon of molten metal flow stoppage in the middle of flow length is discussed based on the non-filled regions in the test pieces.
