A composite mould set for use on a conventional type of injection-moulding machine is made up of composite mould halves (10) which are mounted one on each platen (12) of the injection moulding machine. Each mould half (10) carries an array of injection moulding cavities (16) for moulding preforms, and an array of blow moulding cavities (18) for stretch blow moulding of the preforms into a blow moulded product. The respective cavities (16) and (18) are arranged so that they open in a common mould separation direction.

Une carcasse composite destinée à être utilisée sur une machine de moulage par injection du type classique est constituée de demi-moules composites (10) qui sont installés individuellement sur chaque plateau (12) de la machine de moulage par injection. Chaque demi-moule (10) supporte un ensemble de cavités (16) de moulage par injection servant au moulage de préformes et un ensemble de cavités (18) de moulage par soufflage avec étirage des préformes sous forme d'un produit moulé par soufflage. Les cavités respectives (16) et (18) sont disposées de sorte qu'elles s'ouvrent dans un sens de séparation du moule commun.
