Abstract: A method of manufacturing an aluminum alloy cylinder head includes providing a precision sand core and mold assembly, a liquid aluminum alloy delivery system, and a mold manipulator system. The precision sand core and mold assembly is disposed in the mold manipulator system and the liquid aluminum alloy delivery system includes an in-furnace ultrasonic actuator and a launder tube having at least an ultrasonic actuator. The liquid aluminum alloy delivery system is sealed to the precision sand core and mold assembly and provides liquid aluminum alloy into a gating system of the precision sand core and mold assembly. The precision sand core and mold assembly is rotated approximately 180°. The precision sand core and mold assembly is vibrated.
