The invention relates to a method for operating a temperature control device (116) for the thermal conditioning of preforms (14) made of a thermoplastic material in the temperature control device (116), wherein the respective preform (14) is prepared by the thermal conditioning in the temperature control device (116) for a subsequent forming procedure, in which the preform (14) is formed into a container (12) using a forming fluid supplied under a pressure into the preform (14) and in which the preform (14) is stretched in its axial direction by a stretching unit (11), wherein the temperature control device (116) is regulated in its heating power by a heating regulator (400, B) on the basis of a metrologically determined guide value, and is characterized in that a guide value is metrologically detected, from which the stretching force exerted on the preform (14) is derivable. Furthermore, the invention relates to a temperature control device (116) for the thermal conditioning of preforms (14) made of a thermoplastic material which is regulated on the basis of the guide value, wherein the guide value is derived from the stretching force exerted by the stretching unit (11). Finally, the invention relates to a container production machine having a temperature control device as defined above.

A dual or multi-prong blow pin having air channels and a water cooling manifold integrally formed in the blow mold pin. The pin is formed by 3D depositing a metal such as stainless steel, which permits the formation of a blow mold pin having an intricate shape with internal air and water channels. The use of 3D deposition allows the manufacture such a blow mold pin, which may be difficult or impossible to form using conventional casting and machining methods.

A bottomed tubular-shaped preform is molded into a liquid-containing container holding a content liquid, by supplying, through a first supply path, a first liquid at a predetermined pressure into the preform that has been heated to a predetermined temperature to liquid blow mold the preform and by supplying, through a second supply path that is different from the first supply path, a second liquid into the preform after or simultaneously with the supply of the first liquid.

A liquid blow molding apparatus comprises: a mold (4) in which a preform (2) is to be placed; and a nozzle unit (6) having a supply port (9) capable of supplying a liquid from above into the preform (2) placed in the mold (4), wherein the nozzle unit (6) includes a seal body (13) that is movable among a closed position at which supply of the liquid through the supply port (9) is blocked, a first open position at which supply of the liquid through only part of the supply port (9) in a circumferential direction is allowed, and a second open position at which supply of the liquid through the whole supply port (9) in the circumferential direction is allowed.

This disclosure provides a method of manufacturing a polymer container according to a blow molding or stretch blow molding process, in which the base of the blow mold has at least one orifice for pressurized gas to enter the blow mold through the base. Introducing pressurized gas through the orifice in the blow mold base provides cooling assistance within the gas mold, much earlier than the cooling using conventional methods, which can reduce or eliminate the need for any post mold cooling. This method has been found to be applicable to non-hot fill application bottle and container manufacture.

A liquid blow molding method molds a bottomed tubular-shaped preform into a liquid-containing container in which a content liquid is held. The liquid blow molding method includes: a filling step of filling a first liquid in a first pressurizing source and filling a second liquid in a second pressurizing source; and a molding step of liquid blow molding the preform by simultaneously supplying, to the preform, the first liquid pressurized to a predetermined pressure by the first pressurizing source and the second liquid pressurized to a predetermined pressure by the second pressurizing source by simultaneously operating the first pressurizing source and the second pressurizing source.

A method for packaging liquid products under pressure in thermoplastic containers includes blow-molding a container from a sterilized preform, exposing an exterior of the container to a mixture that includes liquid coolant and either a sterilizing agent or a disinfectant, pressure-filling the container with liquid product, and sealing the filled container.
