ABSTRACT:
A composite extrusion die wherein large extrusion passageways are provided opening to the compression side of the die. Disposed within the extrusion passages towards the discharge side of the die are inserts having a plurality of smaller die passages. The construction provides for effective use of materials for both strength and wear resistance, provides a generous precompaction chamber and allows the concentration of heat buildup to occur locally in the die passage. The construction permits the use of readily formed ceramic or sintered metal inserts which may be mass produced and are readily interchangeable within the die matrix.
