In a press-molding apparatus having upper and lower forming dies (413a, 413b) arranged opposite to each other and upper-die and lower-die heating arrangements for induction-heating the upper and the lower forming dies, the upper-die heating arrangement includes an upper-die induction heating coil (410a), an upper-die power supply (416a), and an upper die temperature controller (417a). The lower-die heating arrangement includes a lower-die induction heating coil (410b), a lower-die power supply 416b, and a lower-die temperature controller (417b). The power supplies are different in oscillation frequency. The upper and the lower forming dies are independently temperature-controlled and heated.
