To provide an extruding press in which the automatic stopping of the press ram is made possible when a extruded product of a prescribed length can not be extruded without the need to input the extrusion completing position of the press ram by the human power.
This extruding press is provided with a first rotary encoder 16 with which the signal of travelling length corresponding to a travelling length from the prescribed position of the press ram 4 of the extruding press 1 with which an extruded product of a prescribed length is manufactured by cutting while extruding raw material powder in a container 2 from a nozzle 2a is outputted. Furthermore, in this extruding press, the traveling length of the extruded product which is extrudable by the advance limit after cutting it on the basis of the signal of the traveling length of one extruded product of the press ram 4 from the extrusion starting position to the first cutting which is outputted from this encoder 16 is calculated and, when the signal of the traveling length corresponding to the traveling length of the number of the extruded product from the encoder 16, a PLC ( programmable logic controller ) 15 for stopping the advancing motion of the press ram 4 is provided.
