Abstract: Disclosed is molding unit for the forming of containers made of thermoplastic material including: two half-molds delimited by a front joint face and by a rear assembly face, with the two half-molds being able to occupy a joined position via their joint face; and a molding cavity that is made of two parts in each joint face, where the cavity opens vertically upward via a passage opening. In the joined position, the assembly faces of the mold have two planes of symmetry that intersect at a central vertical axis of the mold. The central axis of the passage opening is offset transversely in relation to the central axis of the mold.

Abstract: A locking finger for a unit having a molding cavity for molding the container delimited at least by a first shell attached to a first mold carrier and by a second shell attached to a second mold carrier that is movable relative to the first mold carrier between an open position and a closed position, the first mold carrier comprising a control member for controlling the locking finger and the second mold carrier comprising a locking opening, the locking finger comprising an interface for mechanical coupling to the control member, and a locking portion designed to cooperate with the locking opening in the closed position. The molding unit is a subassembly of a plurality of mechanical parts assembled together rigidly, including a main body of the finger comprising the mechanical coupling interface, and said locking portion, which is a main sleeve made from anti-friction material assembled on the main body.

Abstract: A locking finger for a molding unit, the molding unit comprising a cavity for molding the container that is at least defined by a first shell fixed on a first mold holder and by a second shell fixed on a second mold holder that can move relative to the first mold holder between an open position and a closed position, the first mold holder comprising a component for controlling the locking finger and the second mold holder comprising a locking opening, the locking finger including an interface for mechanically coupling to the control component, and a locking portion designed to engage with the locking opening in the closed position. The locking portion comprises an anti-friction composite material.

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.
