PURPOSE:To hold the temp. and pressure patterns while under a hot press working within the reference pattern by providing the sensor for temp. and pressure on the hot press device and providing the device to decide that the measurement value of the temp. and pressure by the sensor is within the controlled reference pattern. CONSTITUTION:Plural hot plates 22 are arranged between a fixed panel 10 and the mobile panel 16 vertically moving by a compacting cylinder 18 and a hot pressing is performed by arranging numerous material 24 to be worked therein. An electric heater is provided on the hot plates 22 and connected to a heating control controller 26. The thermo couple 28 as for the temp. and pressure sensor is assembled on the hot plate 22 and connected to a temp. monitoring controller 32, and a common setter 36, CRT displayer 38 and an audio alarm 40 are connected as well. In case of the hot press working the temp. monitoring controller 32 is controlled by the monitoring program and in case of an abnormality being caused on the work liquid pressure of the compacting cylinder 18 and the temp. controlling state of the hot plate 22 and alarm is displayed by the audio alarm 40, the temp. and pressure are controlled within the controlling reference pattern and the working is stabilized.
