Abstract

A moulding male device for forming a sealing material inside a shell and for obtaining a seal, wherein the male device extends along a longitudinal axis and includes an inner body, which has a front wall configured to press a central portion of an end wall of the shell; an outer body, externally surrounding the inner body, having a front surface configured to press the sealing material, applied at least on an outer portion of the end wall, and to form the seal; a ducting circuit, configured to allow a transit of a cooling fluid inside the male device. The ducting circuit includes an outer circuit at least partly made in the outer body, and wherein the outer body comprises an inner jacket, surrounding the inner body; an outer jacket, surrounding the inner jacket; the outer circuit being at least partly made between the inner jacket and the outer jacket.
