[PROBLEMS] To provide a die-cast article quality judging method for easily judging whether or not a predetermined quality is satisfied, a die-casting machine selecting method for judging whether or not predetermined qualities are met, and a die-casting condition determining method for determining a casting condition. [MEANS FOR SOLVING PROBLEMS] On the basis of the positional relation between the process point (13) which is the intersection of a machine characteristic line (11) and a mold characteristic line (12) and lines (21, 22, 23, 24, 25), it is judged that an inequality limited by judgment criteria Q, Qis not met, and it is judged that an inequality limiting the upper limit of the pouring time and the lower limit of the air-vent exhaust rate is not met. That is, it is judged that a predetermined quality is not satisfied in view of misrun or gas inclusion.
