Abstract
An extrusion press includes a container mover that moves a container at an end platen and molding a product by extruding a billet loaded in the container from a die by a stem driven by a main cylinder device, wherein the extrusion press includes a deflection amount detector that detects a deflection amount of the die; a deflection amount of the die during extrusion is detected; a deviation between the detected deflection amount and a reference deflection amount of the die set in advance is mathematically processed; and the extrusion press includes a controller that sends an output to the container mover to reduce a container sealing force when the deviation is minus, or increase the container sealing force when the deviation is plus so that a container sealing force corresponding to the reference deflection amount acts on an end surface of the die.
