<p>PURPOSE: A metal jet unit is provided to finely control a temperature of a melt metal and a piezoelectric element by including a temperature control unit. CONSTITUTION: A metal jet unit includes a melting furnace(110), an actuator(120), and a piezoelectric element(140). The melting furnace is filled with the melting metal and includes a discharge hole(114a) for discharging the melting metal. The actuator is installed inside the melting furnace and includes a plunger(122) for pressurizing the melting metal to the discharge hole. The piezoelectric elements are installed inside the melting furnace and vibrate the actuator through an amplitude operation.</p> |
