Abstract

The invention shows a dental press furnace comprising a pressing punch () which acts on a green product () made of in particular a ceramic mass—possibly by means of an interposed ram ()—, the green product () being guided in a press channel () which is configured in a muffle (), and a pressure, distance and/or speed sensor detecting at least one motion parameter of the pressing punch (), and comprising a control device for controlling the pressing process based on the output signal of the sensor, the trigger criterion for the start of the pressing process being a change of at least one motion parameter of the pressing punch upon heating and/or softening of the green product which change is detected by means of the sensor.
