Abstract
Described herein is an injection molding or die casting machine having an ultrasonic vibration generator associated therewith that is configured to apply ultrasonic vibrations during melting and/or injection of the molten material (e.g., molten alloy). The ultrasonic vibrations may be applied to molten material via the plunger tip of the plunger in the machine, and/or the mold and/or the vessel, for example. The ultrasonic vibration may be applied during plunger tip movement so that the molten material vibrates ultrasonically during melting and injection. A connector may be connected to the ultrasonic vibration generator and the plunger. Channels may be provided in the plunger tip and/or vessel to accommodate a cooling fluid during melting and injection.
