La transparence est essentiellement liée à la morphologie. L'existence d'une morphologie entraîne l'existence de domaines ayant des indices de réfraction différents, donc réfractant et diffusant la lumière.

Several [internal cooling] systems have been developed that incorporate three basic approaches : liquified gas, super-cold air with water vapor, and air exchange methods. With the liquified gas system, immediately after the parison has been expanded, liquid carbon dioxide or nitrogen is atomized through a nozzle in the blow pin into the interior of the bottle. The liquid quickly vaporizes, removing heat, and exhausts at the end of the cycle. In practice, this method has improved production rates by 25 to 35%. A disadvantage is the cost of the liquified gas. If its consumption is not precisely controlled, the total cost savings becomes minimal.  1, fiche 6, Anglais, - liquified%20gas%20system

Le temps de refroidissement devient pratiquement proportionnel au carré de l'épaisseur, c'est pourquoi on a songé à compléter le refroidissement par contact avec l'empreinte par un refroidissement interne selon les différents procédés décrits ci-après. a) Renouvellement de l'air de soufflage. [...] b) Balayage au dioxyde de carbone. Après soufflage à l'air, on injecte du CO₂ qui, sous forme liquéfiée sous 20 bar à une température de -20 °C, a un pouvoir réfrigérant de 314 kJ/kg (entre -20 et 0 °C). De plus, l'enthalpie de vaporisation de CO₂ élevée (289 kJ/kg) favorise le refroidissement de la paroi interne des corps creux. On peut atteindre une cadence augmentée de 40% à condition, bien entendu, que la capacité d'extrusion en amont le permette.

The [continuous extrusion blow-molding] process has three subcategories : the rising mold method, the rotary method, and the shuttle method. In the rising mold method, the parison is continuously extruded directly above the mold cavity. When it is at the proper length, the mold rises quickly to capture the parison and returns downward to the blow station. After blowing the bottle, the mold opens, the part is removed, and the process repeats.  1, fiche 9, Anglais, - rising%20mold%20method

Other blow molding operations.... Fluorination surface treatment is a process to improve the gas barrier of polyethylene to nonpolar solvents. A barrier is created by the chemical reaction of the fluorine and the polyethylene, which form a thin(20-40 nm) fluorocarbon layer on the bottle surface. Two systems are available for creating the layer. The "in-process" system uses fluorine as a part of the parison expand gas in the blowing operation. The "post-treatment" system requires bottles to be placed in an enclosed chamber filled with fluorine gas. The method forms a barrier layer on both the inside and outside surfaces. This surface treatment allows low-cost, blow-molded polyethylene bottles to be used for paint, paint thinner, lighter fluid, polishes, cleaning solvents, cosmetics, and toiletries. The approach can replace other higher cost resins or coextrusion processes.  1, fiche 10, Anglais, - fluorination%20surface%20treatment

The core rod assembly... has four functions or features : It forms the interior of the preform. It supports the parison or the bottle during transfer. It is the valve where air enters to expand the parison. The valve is located either in the shoulder area or in the tip, the location being governed by the bottle or core rod length-to-diameter ratio. Wide mouth bottles(that is, core rods with low length-to-diameter ratios) will usually have a shoulder valve. The core rod has a "blow by" groove.

Unplasticized PVC presents some processing difficulties due to its high melt viscosity; in addition, the finished product is too brittle for some applications. To overcome these problems and to produce toughening, certain polymeric additives are usually added to the PVC. These materials, known as impact modifiers, are generally semicompatible and often somewhat rubbery in nature. Among the most important impact modifiers in use today are butadiene-acrylonitrile copolymers (nitrile rubber), acrylonitrile-butadiene-styrene (ABS) graft terpolymers, methacrylate-butadiene-styrene (MBS) terpolymers, chlorinated polyethylene, and some polyacrylates.  4, fiche 12, Anglais, - impact%20modifier

Extrusion stretch blow moulding(ESBM). A parison is extruded and as the preblow mould closes, a mandrel descends to form the bottle neck. The parison is subsequently pinched and inflated, then conditioned at the optimum temperature for orientation in the next stage. Transfer of the blown and conditioned preform to the stretch-blow mould takes place; fabrication of the finished part is achieved by stretching in the circumferential direction(pneumatic inflation) and in the longitudinal direction(mechanical push-rod), followed by rapid cooling to prevent relaxation of the(biaxial) molecular orientation. This process is centred on oriented PVC(OPVC) bottle manufacture, for transparent containers with enhanced clarity and greater resistance to gas permeation, higher impact strength and burst pressure.  1, fiche 13, Anglais, - extrusion%20stretch%20blow%20moulding

Another process somewhat related to extrusion blow molding is the extrusion/molded neck process. Still used today by Owens-Illinois, this is a proprietary process that traces its roots to glass-blowing technology. It is unique in that the bottle neck finish is injection molded and the bottle body is extrusion blow-molded. In this process, the two halves of a neck finish cavity or neckring are mounted to an actuating head assembly, which intermeshes with the two halves of the blow-mold cavity. The process cycle begins with the main body mold cavity open and the neckring cavity closed. The actuating head assembly moves downward to contact the extrusion die head. When it is in position, extrusion pressure fills the neck section with plastic melt. After it is held for one to two seconds, the head assembly moves upward while, simultaneously, the parison is extruded. When the head assembly reaches the top of its stroke, the blow-mold cavity closes on the parison. The remaining steps of parison pinch-off, blowing, and part removal all follow conventional techniques. Although the production cycle is somewhat slow, the process offers the quality advantage of an accurately molded neck and the process advantage of a parison held at both ends.  1, fiche 14, Anglais, - extrusion%20molded%20neck%20blow%2Dmolding%20process

Intermittent extrusion is the second basic extrusion blow-molding category. In this process the parison is quickly extruded after the bottle is removed from the mold. The mold clamping mechanism does not need to transfer to a blowing station. Blow molding, cooling, and part removal all take place under the extrusion head, which also allows the clamping system to be more simple and rugged. The stop/start aspect of the extrusion method makes this process more suitable for polyolefin and other materials that are not heat-sensitive.  2, fiche 16, Anglais, - intermittent%20extrusion
