Method and apparatus for applying a vibration to melt within an injection mold includes at least one first fixed surface, at least one active material element mounted on the at least one fixed surface, and at least one second movable surface adjacent the at least one active material element. In the method, at least one active material element is activated intermittently to move the at least one second movable surface with respect to the at least one fixed surface. In the apparatus, a wiring conduit is coupled to the active material insert, and is configured to carry vibration signal to the at least one active material element.
