Lightweight aluminum alloy materials have become the most widely used non-ferrous metal materials in society. Taking 7xxx series aluminum alloy as the research object
which introduced the application direction of its profile produced by extrusion. The main factors affecting extrusion processing are analyzed
and taking electromagnetic stirring technology
as an example
to produce the large-scale casting. That listed the construction and ability of large-scale hydraulic extruder in the world
described the mold manufacturing process from CAD/CAE/CAM software design to CNC machining center
and compared the characteristics of forward extrusion
backward and other processes
the improvement measures of hydraulic system and isothermal processing are given. Last
the effect of extrusion times on the microstructure and properties of the materials was observed
which provides a reference for the extrusion processing.
