Abstract
L'invention concerne un objet articulé d'un seul tenant en matière plastique et son procédé de moulage. Un tel objet est moulé en injectant un mélange fluide d'un polymère et d'un agent de soufflage dans la cavité d'un moule extensible de manière qu'il la remplisse à l'état sans mousse, mais à la température de moussage Le moule est déployé de façon à former des parties de l'objet ayant une âme en mousse, tandis que la résine située à proximité de la surface du moule est encore fluide, et un élément de façonnage de l'articulation est maintenu en position pour former une partie flexible mince sans mousse, tandis que des parties de transition divergentes permettent une augmentation progressive de l'épaisseur de la mousse centrale entre la partie flexible et les panneaux de l'objet qui présentent une ame de mousse d'épaisseur normale. Application à la réalisation d'un objet articulé présentant une ame en mousse dans ses panneaux.
