The invention concerns a method for monitoring a process during die casting or thixotropic moulding of metals (14, 15) in a die casting or thixotropic moulding device. The time curve of the moulding pressure p(t) and the speed v(t), a time-based, of the casting piston (12) are determined. On the basis of the time-based curve of the moulding pressure p(t) and speed v(t) of the casting piston, the energy E(t) supplied by the casting piston (12) based on , the time of the process (t) and the total energy Etot supplied by the casting piston (12) during the die casting process or the thixotropic moulding are calculated, the total energy Etot being used as parameter for monitoring the die …
