“…Compared with an audible sound, the ultrasonic wave is of very high frequency, and the direction of propagation can be ensured very well within a small space. Since the acceleration of medium particles in ultrasonic transmission is very large, the ultrasonic wave can exert a significant effect on the energy of the medium material [15,16]. Thereby, in this investigation, the ultrasonic wave is employed on the polymer melt to improve the flow property by the energy exchange between the ultrasonic wave and the melt polymer.…”

An ultrasound-assisted micro-injection molding method is proposed to improve the rheological behavior of the polymer melt radically, and a micro-injection molding system based on a longitudinal ultrasonic vibration core is developed and employed in the micro-injection molding process of Fresnel lenses. The verification experiments show that the filling mold area of the polymer melt is increased by 6.08% to 19.12%, and the symmetric deviation of the Fresnel lens is improved 15.62% on average. This method improved the filling performance and replication quality of the polymer melt in the injection molding process effectively.
