Blow moulding machine, preforms, system and process
A continuous non-symmetric preform feed stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric injection moulded preforms; the non-symmetrical preforms including an integral handle extending from a first junction point to a second junction point on a body of the preform; the body of the preform and the integral handle constituted from the same material.
Container mold and method of manufacturing a container
A container mold includes: a split mold that has a mold space defining a shape of a body portion of a container; and a bottom mold that has a bottom mold surface defining a shape of a bottom surface of the container and is movable forward and backward with respect to the split mold. The split mold includes a bottom mold reception portion that is communicated with a bottom portion side of the mold space and receives the bottom mold. When the bottom mold is closed with respect to the split mold, a space between a surface of the bottom mold reception portion facing the bottom mold surface and the bottom mold surface is a space that defines a shape of a structure protruding in a radial direction of the container.

PREFORM HEATING SYSTEM
The present invention relates to a heating system for preforms upstream of a blowing or stretch-blowing machine, in particular a heating system using monochromatic infrared radiation, preferably laser-generated.
In particular, the invention relates to a heating system (301) for preforms (P), comprising a carousel for treating the preforms (P) comprising a plurality of heating elements (304) configured to be inserted either inside or outside each preform (P) and to radiate electromagnetic radiation in the infrared field which forms, in such a device, a disc of radiation according to a radial symmetry which departs from the center of the axis of the preform and which appropriately converges and diverges.

PRIMARY REFLECTOR FOR A HEATING MODULE OF A HEATING DUCT IN A MOULDING MACHINE FOR MOULDING CONTAINERS FROM PREFORMS
The invention relates to a heating module and a primary reflector for a heating module of a heating duct of a molding machine for producing containers from preforms, in which preforms made of thermoplastic are heated, which is provided between tubular heating units arranged in parallel and one over another on a side wall of the heating module and the side wall and consists of ceramic material, and is characterized in that the primary reflector is connected via a dovetail connection to the side wall, wherein a connecting region in the form of a dovetail is formed in each case on the reflector, which is fixable in each case with a clip made of steel, in particular spring steel, fastened on the side wall, having dimensions adapted to the dovetail.
METHOD FOR FABRICATING CONTAINERS
A method of fabricating a container from a substantially tubular preform. The preform is preheated to a temperature above the glass-transition temperature of the preform and placed in an expansion zone configured to accommodate the preform and in fluid communication with the nozzle of an injection head. The expansion zone is disposed adjacent to the nozzle and about the longitudinal axis defined by the injection head. A volume of an injection liquid is injected from the injection head into the preform cavity of the preform while the preform is in the expansion zone and the preform is expanded, while still in the expansion zone, into a container. Concurrently with the injecting and expanding of the preform, the preform is heated by energizing a plurality of infrared-emitting elements disposed about the preform and projecting infrared radiation into the expansion zone.
