Abstract

Le procédé d'éjection de pièces obtenues par coulage forgeage de pièces en alliage léger, en aluminium ou alliage aluminium, ou tous autres matériaux, est remarquable en ce qu'il consiste à déporter les zones réceptrices des éjecteurs hors du corps de la préforme considérée, en les implantant sur la bordure périphérique latérale (2a) de la préforme, et en ce que pendant la phase de forgeage, lesdites zones (2b) permettant l'éjection de la préforme se retrouvent dans la bavure de la pièce forgée et sont découpées et évacuées en même temps que la bavure.
