A feed block unit for a hot-runner feed system of a pressure die-casting machine includes a block body in which is incorporated at least one melt-conveying channel running out of the block body by way of a sprue orifice close to the gate, and a heating system, integrated into the block body, for the at least one melt-conveying channel. The feed block unit is designed as a structural unit which is insertable independently into a respective casting mold, and/or the heating system integrated therein includes at least a first heating device for supply channel heating and a second heating device, which can be controlled independently of the first heating device, for sprue channel heating. With this modular hot-runner feed system, individual temperature profiles can be predetermined and set for the respective feed block unit.

With this modular hot-runner feed system, individual temperature profiles can be predetermined and set for the respective feed block unit. A control device authorizes a mold-filling operating to take place dependent on whether temperatures detected in the hot-runner feed system lie within predeterminable setpoint temperature ranges.
