Title (DE) VERFAHREN ZUR HERSTELLUNG VON FORMTEILEN AUS HEISSHÄRTENDEN KUNSTSTOFFEN
(EN) METHOD OF MANUFACTURING MOULDINGS FROM HOT-CURING PLASTICS
(FR) PROCEDE DE PRODUCTION DE PIECES MOULEES EN PLASTIQUE A DURCISSEMENT A CHAUD
Abstract:
(DE) Bei der Herstellung von Formteilen aus heisshärtenden Kunststoffen durch Niederdruckgiessen innerhalb einer räumlich begrenzten Umgebung, die durch ein isolierendes Gas angereichert ist, wird letzteres nach einem Giessvorgang durch Zufuhr eines gasförmigen Mediums aus der Umgebung zur Weiterverwendung in einen Auffangraum verdrängt.
(EN) The invention concerns the manufacture of mouldings from hot-curing plastics by low-pressure casting in a dimensionally restricted space enriched with an insulating gas. After each casting operation, the insulating gas is flushed, by means of a gaseous fluid, out of the space and into a collection space so that it can be re-used.
(FR) L'invention concerne la production de pièces moulées réalisées en matières plastiques à durcissement à chaud par coulée basse pression à l'intérieur d'un espace délimité enrichi avec un gaz isolant. Après chaque opération de coulée, le gaz est refoulé dudit espace vers un collecteur par apport d'une substance gazeuse afin d'être utilisé ultérieurement.
