1. Method for determining a target value for a control parameter in a casting process, which control parameter relates to melting of a casting compound, filling of a mold cavity (4) with the casting compound and/or cooling of the casting compound filled into the mold cavity (4), wherein the casting compound in liquid phase is filled under pressure at least once into the mold cavity (4) formed by two mold halves, a clamping force being exerted on the mold halves during filling of the mold cavity (4), characterized in that,at least one curve of a variable for characterizing the clamping force is measured,determining a relationship between the measured profile or a variable derived from the measured profile on the one hand and a parameter of the casting process on the other hand, andfrom this relationship, a setpoint value for the control variable is determined.
