| 1. A method, comprising:
transferring molten process material directly to a die-casting machine including a shot-sleeve; and
ultrasonic processing molten process material in the shot sleeve,
wherein transferring includes inserting an ultrasonic processor into an opening in the shot-sleeve just ahead of an injection
ram, retracting the ultrasonic processor into the opening in the shot-sleeve just ahead of the injection ram, and advancing
the ultrasonic processor and the injection ram toward a casting die sufficiently to close the opening, the opening having
an extension therein to accommodate advance of the ultrasonic processor.
