A method for manufacturing a prosthetic hip acetabulum includes the steps of: a) providing an insertion cup (1) having an inner concave receiving surface (3) having an opening surface (5) contained in an opening plane (P), and having an outer annular receiving structure (6); b) providing an installation and positioning insert (7) having a peripheral annular attachment structure (10) shaped to engage with the receiving surface (9) of the outer annular receiving structure (6) fitting around the annular outer receiving structure (6); c) heating the installation and positioning insert (7) in order to increase the size of the insert (7), d) fitting the peripheral annular attachment structure (10) around the receiving surface (9) of the outer annular receiving structure (6); e) cooling the installation and positioning insert (7) to room temperature in order to reduce the size of the insert (7) and achieve radial tightening of the peripheral annular attachment structure (10) on the outer annular receiving structure (6).
