Abstract

Blocks formed from metal scrap are extruded through the die of an extrusion press by introducing the block in the block receiver of the extrusion press. Before the scrap is extruded by the pressure of the main extrusion press cylinder through the die, all air is evacuated from the block in the receiver. This is done by isolating the block in the receiver and applying a vacuum to it, preferably accompanied by an additional compacting force. This eliminates the appearance of air bubbles or air inclusions in the extruded product or on its surface. The extrusions therefore have a much higher quality.
