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.

A blow mould includes at least first and second blow mould elements that inscribe a concavity; and at least one insert having an embossed surface to form a pattern onto a blow-moulded surface. The at least one insert is attached onto a surface of at least one of the first and/or second blow mould elements to form a part of the wall of the blow-moulded product. Such blow mould is an ISBM blow mould and the blow mould is such that the at least one insert is a plate having a wall thickness of between 0.2 mm and 2.0 mm and is attached onto at least one of the first and/or second blow mould elements by a reversible fixation mechanism selected from the group of adhesives, preferably a double-sided adhesive tape, a magnet and a geometric mechanism.

The present invention relates to a mold bottom extending about a central axis and comprising a molding wall made as a single piece and defining a molding surface; a cavity formed inside the molding wall, and having a central area, a peripheral area, and a middle area; a central pipe supplying the cavity with heat-transfer fluid, that opens in the central area via one or more central openings; and at least one pipe for discharging the heat-transfer fluid from the cavity, into which the peripheral area opens. According to the invention, the mold bottom comprises a bypass that brings the central pipe into direct communication with the middle area of the cavity by bypassing the central area.

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.

A modular system for blow molding a container. The system may include a first portion, a second portion, and a third portion. The first portion and second portion may each include a shell, a mold removably coupled to the shell, and a top plate. The third portion may include a base and a base mold. The molds may be 3D printed. The molds together may define a blow mold cavity. The modular system may be used at lab scale, pilot scale, or full production scale. The molds may be durable and smooth enough for full production scale. Some embodiments are directed to methods for making a modular system for blow molding a container.

Such blow mould is an ISBM blow mould and the blow mould is such that the at least one insert is a plate having a wall thickness of between 0.2 mm and 2.0 mm and is attached onto at least one of the first and/or second blow mould elements by a reversible fixation mechanism selected from the group of adhesives, preferably a double-sided adhesive tape, a magnet and a geometric mechanism.

A method for improving the impact resistance of an extrusion blow molded article by extrusion blow molding an ultra-high IV polymer resin having an IV of at least 0.9 dL/g, wherein the extrusion blow molding is carried out in a mold with a texturized base surface such that a base surface of the extrusion blow molded article is textured.

The invention relates to a method for assisting in the programming of an electronic control unit of a forming station comprising molding units, each of which has an interchangeable mold, the method comprising a manual programming step consisting in selecting a value for determined operating parameters through a data entry interface in the electronic control unit, wherein each mold has fastened thereto a storage component having values compatible with each mold for each determined parameter, is attached to said mold, the method comprising a prior step of reading the values stored in the storage component by means of a reader which automatically transmits the values to the electronic control unit to limit the choice of values of each parameter to the compatible values.

Mold base including a base wall and a peripheral side wall which is connected to the base wall by a fillet, this mould base ending with a peripheral upper edge and including ribs forming cavities for grooves for strengthening the base of a container to be formed and which each straddle the fillet, this mould base also including decompression vents hollowed out of the moulding face and which include, for each rib, at least one pair of shallow side channels which extend on either side of the rib and open, at an upper end, on to the peripheral upper edge.

The invention relates to a tank of plastics material produced by blow-molding of a parison, incorporating a welding spout, of a shape projecting from its outer surface which has an edge configured to be welded to a corresponding edge of an attached part, the welding spout ending axially, on an inside of the tank, in a shape resulting from contact molding between the parison and a molding component, in which the welding spout ends axially on an outside of the tank in a shape resulting from contact molding between the parison and a molding component.
