An improved apparatus and method for metal extrusion applications and presses
wherein high purity inert and/or partially inert gases are introduced at or near
the die exit. The environment at or near the exit is also preferably analyzed and/or
monitored on a continual or nearly continual basis. The environment is also preferably
controlled to which minimize or eliminate oxidation of metals and other extruded
materials. The apparatus and method allow faster extrusion rates, improved surface
quality of the extruded materials, and increased die life. In an embodiment, bi-phasic
inerting media may also be used.
