Claim 10:
11. The method according to claim 1, wherein the ultrasonic vibration device is a first ultrasound vibration device; wherein the apparatus includes a second ultrasound vibration device; and wherein the method further comprises:
simultaneously with flow initiation through the outlet, or after the flow has been initiated, turning the second ultrasound vibration device from an off-state to an on-state to expose the molten injection moulding material in the flow chamber to ultrasonic vibration during flow; and
turning the second ultrasound vibration device from the on-state to the off-state when the mould tool cavity is full, such that statis molten injection moulding material in the flow chamber is not exposed to ultrasonic vibration before the next injection cycle is started.
