The processing method of the metal shell metal casing, a data interface and data interface of the processing equipment, the processing method comprises the following steps: providing a metal flat tube (200); the metal flat tube (200) is set in the core (111), of which the core (111) along the core (111) the axis direction setting core segment has at least two different sizes (114115116117); using at least two cavity (12211222122312241225) and core (111) with extrusion metal flat tube (200), by which the metal flat tube (200) along the core (111) in the axial direction respectively and extrusion the core section (114115116117) corresponding to the metal pipe (301302303304). By extruding the metal tube in step by step, the special-shaped complex metal tube with poor tensile property can be made into a metal casing of different shapes, and the metal tube can be prevented from cracking.
