A method for operating a fuel injection - or die-casting machine and for this purpose - injection molding or die-casting machine

摘要

A method for operating a fuel injection - or die-casting machine (201) with a of a drive means controllable piston-like device (2) for the injection of molten material in a mold cavity (205, 206, 208), of the at least two surrounding partial group (205 and 206 and 208) of different cross-sections for the molten material to be injected, characterized in that the piston-like device (2) of the drive device in the sense of an at least approximately even out of the flow velocity of the molten material inside the partial group consists of different cross section of the mold cavity is governed in such a way that the material when reaching a the form of channel having a smaller cross section of the piston-like device more slowly than in the case of passage is injected by means of a molding channel having a larger cross-section.
