ABSTRACT:
A diecasting process for producing cast pieces for metals or their alloys by means of a horizontal cold chamber diecasting machine. The diecasting machine includes a diecasting mold held under a vacuum, a fill chamber coupled to the diecasting mold, a holding furnace containing metal melt, a suction pipe partially immersed in the holding furnace and coupled to the fill chamber, means for transporting metal melt from the holding furnace through the suction pipe into the fill chamber under a vacuum, and means for moving the metal melt from the fill chamber into the diecasting mold. During the dosaging phase when the fill chamber is filled with metal melt, gases and lubricant vapors are developed upon entry of the melt into the fill chamber. The process includes the steps of maintaining the vacuum in the fill chamber during the dosaging phase until the gases and lubricant vapors so developed have been substantially extracted and maintaining the vacuum in the fill chamber to its maximum extent until the diecasting mold is completely filled with the metal melt.
