A method for process monitoring during die casting or vacuum thixoforming of metals in a mold, wherein the time lapse of temperature (T) is continuously measured on at least one point of the system and the temperature progression of the system is calculated in real time using a program. The time lapse of the heat flow (W) is calculated from the temperature progression of the system and the time lapse of the energy (U) of the system and the solidification heat portion (U ) of the metal solidified in the mold are calculated from the heat flow. At a given time, the calculated values are used as monitoring parameters.

Method for process monitoring during die casting or thixoforming of metals

The apparatus includes a diecasting mold and evacuation elements for the controlled evacuation of a mold cavity. The evacuation elements includes a vacuum tank and a suction line interconnecting the vacuum tank and the diecasting mold. the suction line includes a first valve and a second valve which is coupled in parallel to the first valve. The valves are arranged so that a reference space is formed therebetween. The method for manufacturing die-castings includes evacuating a diecasting mold, filling the diecasting mold with casting material, removing the die-casting, forming a reference space in a portion of the suction line by closing the two valves which are coupled in parallel, measuring moisture, and pressure and temperature in the reference space, and controlling the apparatus in accordance with the measured values.
