Claim:
A mold-tool system ( 100 ) configured to accommodate a valve stem ( 104 ), the mold-tool system ( 100 ) comprising: a nozzle assembly ( 402 ) having: a nozzle-output end ( 408 ) being configured to support, at least in part, slide movement of the valve stem ( 104 ), and a nozzle tip ( 114 ) being received in the nozzle-output end ( 408 ), the nozzle tip ( 114 ) including: a flute structure ( 116 ) positioned proximate to an exit portal ( 118 ) of the nozzle tip ( 114 ), the flute structure ( 116 ) configured to slidably support the valve stem ( 104 ) while at the same time maintaining a flow area ( 400 ) surrounding the valve stem ( 104 ) along the entire length that the valve stem ( 104 ) is slidably supported by the flute structure ( 116 ) when the valve stem ( 104 ) is placed in the open position, the flow area ( 400 ) being equal to the flow area ( 300 ) defined by a cross sectional area of the exit portal ( 118 ) of the nozzle tip ( 114 ).
