Method for monitoring a process during metal die casting or thixotropic moulding |
摘要 |
A method for process monitoring during diecasting or thixotropic molding of metals in a diecasting or thixotropic molding installation which contains a casting chamber, a casting piston and a mould with a mold cavity. The method includes measuring temporal development of molding pressure p(t), determining time-related speed of the casting piston v(t); calculating energy E(t) supplied by the casting piston as a function of process time t, and calculating total energy Etot supplied by the casting piston during the diecasting or thixotropic molding process based on time-related development of the moulding pressure p(t) and the casting piston speed v(t), and using the total energy Etot as a parameter for monitoring the diecasting or thixotropic molding process.
