Abstract (en)
[origin: EP1072340A1] Process for monitoring die casting or thixoforming of metals (14) in a die casting or thixoforming device containing a casting chamber (10), a plunger (12) and a mold with cavities (16, 18) comprises measuring the periodic course of the pressure and determining the time-dependent speed of the plunger, calculating energy introduced through the plunger as a function of the process time and the total energy introduced during die casting and/or thixoforming through the plunger based on the time-dependent course of the pressure and the plunger speed, and using the total energy as a parameter for the monitoring of the process.
