Abstract
The invention relates to an ultrasonic device for molding micro plastic parts, which combines: a) a mold cavity configured in a mold having an inlet for supplying plastic material to a chamber with an access opening and the chamber facing the cavity at a distal end in relation to its access opening; b) a cantilevered ultrasonic vibration element associated with an ultrasound generator, with an end portion or tip inserted tightly into the chamber through the access opening in an axially centered manner; c) a movement device for generating a relative movement between the end portion and the parts of the mold so that the end portion engages with the supplied plastic material and exerts a pressure of pre-determined magnitude thereon upon activation of the ultrasonic vibration element.
