Abstract
In a hot chamber die-casting machine, inductively-operating heating devices are associated with the mouthpiece area of the casting container and the nozzle. All of these heating devices are operated with medium frequency. The inductors are cooled with air. The machine is useful for hot chamber die-casting machines that process magnesium.
