Provided is a method of producing a container by deforming a heated preform. The method includes: determining at least two formed zones along the container axis in the body, said formed zones being produced using a different quantity of material, each formed zone corresponding to at least one heated zone of a body of the preform; heating the body of the preform using at least two heating elements that each heat one of the heated zones of the body of the preform; deforming the heated preform to form the container; and before the step of heating the body of the preform, adjusting a heating power of each heating element wherein the heating power of each heating element is adjusted as a function of the quantity of material in the formed zone of the body of the container corresponding to the zone heated by each heating element.

A method and system for manufacturing containers are disclosed. The system includes one or more manufacturing cells comprised of an unloading station, a queuing/sequencing station, a heating station, an unloading station, and a molding station. The queuing/sequencing station utilizes a plurality of carrier shuttles configured to traverse a platform comprised of a plurality of induction coil sections. Each of the carrier shuttles is provided with a preform mount for receiving a preform thereon. The preforms are selected and the carrier shuttles are arranged in accordance with a predetermined sequence. At least one heater of the heating station is disposed over one of the induction coil sections and adapted to heat the preform. The heated preforms are transported by the carrier shuttles from the heating station to an unloading station, which transitions them to the molding station for a fluid (e.g., gas or liquid) blow molding operation to form the containers.

A container treatment system includes a production machine for preforms, a blow molding machine and at least one heat exchange device. The production machine and the blow molding machine are interlocked with one another, and the at least one heat exchange device is configured for heat exchange between the production machine and at least one component of the container treatment system.

Ways to produce a plurality of preform (5) temperature profiles are provided that employ systems having a first heating means, a second heating means, and a first transfer means. The a first heating means has a first preform (5) path, imparts a first temperature profile to a preform (5) passing through the first preform (5) path, and has a first dispensing means configured to selectively dispense the preform (5) passing through at least a portion of the first preform (5) path. The second heating means has a second preform (5) path, imparts a second temperature profile to a preform (5) passing through the second preform (5) path, and has a second dispensing means configured to selectively dispense the preform (5) passing through at least a portion of the second preform (5) path. The first transfer means selectively transfers a preform (5) between the first preform (5) path and the second preform (5) path.

A heating system (2) for heating plastic material preforms upstream of a blow molding or stretch-blow molding machine (3), the system comprising a heating module (4) adapted to be crossed by a plurality of preforms (5) advancing along a transport line (14), wherein the heating module (4) is provided with a plurality of heating elements (12, 13) arranged along a plane substantially parallel to a plane containing the axes of the preforms adapted to cross said heating module, wherein the heating module (4) comprises a first heating zone (10), proximal to a support area of the neck of the preforms and comprising at least one first heating element (12) of said plurality of heating elements, and at least one second heating zone (11), arranged adjacent to said first heating zone (10) and at a passage zone of the tubular body of the preforms, and comprising at least one second heating element (13) of said plurality of heating elements, wherein the heating system (2) further comprises at least one first temperature sensor (8) arranged externally to the heating module (4) and at said first heating zone, and at least one second temperature sensor (9) arranged externally to the heating module (4) and at said at least one second heating zone.

An Infrared heating system (101) designed for the efficient heating of preformed plastic tubes (106). The system comprises an infrared housing unit with multiple longitudinal strips (107N) of infrared heating elements (103), surpassing the length of the preformed tubes. A handling arrangement involving a series of rollers (202) facilitates the simultaneous oscillation and rotation of the plastic pipes. The inner surface of the infrared housing (102) features strategically positioned reflectors (109N) to enhance the infrared heating effect. The handling arrangement includes longitudinally spaced motorized rollers for axial movement, and motorized wheels (110) and tracks (111) for transverse movement. The infrared housing unit offers multiple temperature zones to suit the characteristics of the plastic pipes and employs temperature sensors (114N) for uniform and precise temperature control. A corresponding process for heating preformed plastic pipes is also described, integrating these features for effective and controlled heating.

An injection blow molding apparatus includes: a male mold portion; a female mold portion; a gripping mold portion; an injection unit that injects a resin for molding a preform into inner surfaces of the female mold portion, the male mold portion, and the gripping mold portion; a blow unit that is released from the female mold portion and the male mold portion and blows air into the preform in a state in which the gripping mold portion has gripped the preform; and a control unit that releases the preform from the male mold portion before the preform is released from the female mold portion in a mold release process of releasing the preform from the female mold portion and the male mold portion.
