Description

Technical Field

[0001] This application relates to the field of aluminum tube forming equipment technology, and in particular to an aluminum tube extrusion forming machine. Background Technology

[0002] Aluminum extrusion molding (or aluminum extrusion forming) is a method of applying strong pressure to an aluminum billet placed in (or extrusion cylinder) to force the aluminum billet to orient itself and extrude it from the die orifice of an extrusion die, thereby obtaining a part or semi-finished product of the required size and with certain mechanical properties.
