Title (EN) METHOD OF MANUFACTURE OF A CONTAINER
(FR) PROCÉDÉ DE FABRICATION D'UN RÉCIPIENT
Abstract:
(EN) A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article (16). The intermediate article is trimmed to form a finished container (38). The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive.
(FR) L'invention concerne un procédé comprenant le moulage par injection d'une préforme à l'aide d'un système d'injection à deux phases présentant une première phase, dans laquelle un matériau est injecté dans la préforme, et une deuxième phase, dans laquelle le matériau est injecté dans la préforme. La préforme est disposée dans un moule. La préforme est moulée par soufflage en un article intermédiaire (16). L'article intermédiaire est ébavuré pour former un récipient fini (38). La première phase comprend l'injection d'un matériau dans la préforme pour former une couche unique de la préforme et la deuxième phase comprend l'injection du matériau pour former des couches interne et externe et une couche intermédiaire entre les couches interne et externe. Les couches interne et externe comprennent le matériau et la couche intermédiaire comprend au moins un additif.
