METHOD OF REMODELING A SKULL FROM AN EMPTY METAL CONTAINER, APPLIANCE, TYPICALLY A PRESS, TO APPLY THE MENTIONED METHOD, AND, USE OF METHOD

摘要

method of reshaping a skirt of a cast metal container, apparatus, typically a press, for applying said method, and method use. said method, wherein: a) said container (1, 6) is placed in a mold (2) of two halves having an internal molded wall (21), and b) an internal pressure p of a fluid, typically air, is accumulated during a time lapse 30 is within said hollow container forming a cavity (15) so as to shape said skirt (12) by expanding it against said patterned wall (21), said patterned wall (21) having an inner surface (210) defining a side space (211) typically maintained at atmospheric pressure, where an external pressure p of a fluid, typically air, is applied to said upper space (101) adjacent to an outer or upper surface ( 100) of said open top end (10) and / or in said lower space (141) adjoining an outer or lower surface (140) of said shaped bottom end (14) so as to have during mentioned time lapse 30 t, a difference pressure 30 p = ip - pi sufficiently low to prevent any distortion of said shaped open end end (10) and / or said shaped bottom end (14) to form a shaped metal container (1 , 6), an apparatus for performing the method is also disclosed.
