Abstract (en)
The invention relates to a nozzle (1) for die-casting apparatus, used to inject into a mould the molten metal coming from the hot chamber. <??>In particular, this nozzle is intended for high-temperature applications such as the die-casting of magnesium alloys; for this purpose, to heat efficiently the molten metal outflow channel, cavities are provided in the nozzle body (2) around the channel, in which heating resistances are housed. <??>Advantageously, the latter consist of a high-resistance filament immersed in zirconium powder contained in the cavities. <IMAGE>
