Abstract: The invention relates to a half-mold comprising a joint face; an opposing assembly face), where the longitudinal cross-section of the assembly face is in the form of an arc of a circle centered on a reference axis. The reference axis is offset longitudinally towards the front relative to the joint face. The invention also concerns a molding assembly, a molding unit and a forming facility comprising such half-molds. The invention also concerns a method for producing such half-molds and a method for producing a surface for receiving such half-molds.

Abstract: A molding unit (10) for manufacturing preforms (100) made of plastics material, includes at least one “HR”-type mold (10), a nozzle (14) including at least a nozzle body (28) and a nozzle orifice (30) incorporating a preform (100) stabilizer (34) that forms with a tubular member (40) a mobile assembly that is able to slide axially relative to the nozzle orifice (30) between at least a top position and a bottom position, wherein the tubular member (40) is guided so as to slide axially with respect to the nozzle body (28) by at least one guiding element (46) which is interposed radially between the nozzle body (28) and the tubular inlet member (40), and the stabilizer (34), fixed to the tubular member (40), is guided with respect to the nozzle body (28) only by way of the at least one guiding element (46).

Abstract: A molding unit for producing a container, that includes: —a mold having the footprint of the container, including a pair of shells each having an inner wall; —a pair of shell holders onto each of which a shell is removably attached; —a device for controlling the temperature of the mold, that includes: ?at least one radiator integrated into a shell holder, ?at least one temperature probe integrated into a shell, for measuring the temperature in the vicinity of the inner wall, ?a variator connected to the temperature probe and to the radiator, the variator being arranged to modulate the temperature of the radiator depending on the temperature measured by the probe.
