A method for injection molding of a liquid metal - component and the nozzle for spraying metal

摘要

During the injection molding of a liquid metal - component, this by means of a nozzle is introduced into a cavity. In this case, it is provided that a transition region between the nozzle and of the cavity (gate region,,) after the introduction of the metal - component in the cavity is cooled in such that the metal solidifies in the gate region. In a later process step, the gate region, are again heated, as a result of which in the gate region siech metal liquefied again. A corresponding nozzle for spraying of metal has a nozzle pipe, which forms a melt, and a heating element, with which the nozzle pipe is to be heatable. An outlet opening of the nozzle pipe is closed by means of a valve. In addition, in the region of the outlet opening a refrigerating.
