Abstract
A method for cleaning inner surfaces of a container on an indirect extrusion press, using a loose die including an extruding die portion and a separable cleaning die portion. The die is continuously used after contributing to the cleaning in each cycle of press operation, replacing the cleaning die portion alone in an ejected position after extrusion of a billet.
