ABSTRACT:
A method of and device for making rods, tubes and profiled articles directly from a melt, especially metallic melt, by extrusion pressing by means of a forming tool and die. The melt charged into a receiving compartment of the device in successive batches is cooled so as to be transformed into a thermal-plastic condition. There is a build up layer by layer to form a bar and alternately with the charging of the receiving compartment the bar stepwise is subjected to pressure to extrude a portion of a strand.
