Title (EN) SYSTEM AND PROCESS FOR VACUUM MOLDING
(FR) SYSTÈME ET PROCÉDÉ DE MOULAGE SOUS VIDE
Abstract:
(EN) A system is described, for making a moulded article made of foamed material, comprising a die (1) composed of an upper section (11) and a lower section (12), separable and coupled to define a recess, first sucking means (20) to create a vacuum to allow shaping a plastic film on the wall of a portion of the recess of the sections (11) and (12), tensioning and locking means (30) of the plastic film to allow positioning and fastening the plastic film outside the recess.
(FR) L'invention concerne un système permettant de fabriquer un article moulé composé d'un matériau expansé, comprenant une matrice (1) composée d'une section supérieure (11) et d'une section inférieure (12), séparables et accouplées pour définir un évidement, un premier moyen d'aspiration (20) permettant de créer un vide pour permettre la mise en forme d'un film plastique sur la paroi d'une partie de l'évidement des sections (11) et (12), et des moyens de tension et de verrouillage (30) du film plastique pour permettre le positionnement et la fixation du film plastique à l'extérieur de l'évidement.
