Abstract (en)

[origin: WO2013071926A2] Diecasting nozzle for use in a diecasting hot chamber system for metal melts, comprising at least one melt channel (4) in a channel carrier (3) that can be connected to a melt distributor (21), wherein the melt channel (4) goes over into a heating zone (6) and a nozzle tip (8), which is adjoined by a sprue region (10), in which there can form a plug of solidified melt that interrupts a melt flow, wherein the heating zone (6) has a heating cartridge (2) and/or a heatable nozzle shaft (33') and/or the nozzle tip (8) is configured as a heatable nozzle tip (8') and at least the heating cartridge (2), the heatable nozzle shaft (33') or the heatable nozzle tip (8') is configured as a heating element with electrical heating, which has a high power density in at least one subregion and low thermal inertia, configured in such a way that a temperature variation gradient of 20 to 250 K/s, preferably 150 K/s, can be achieved at the surface of the heating element. The invention similarly relates to a method for operating the diecasting nozzle.
