Title
(EN) INVESTMENT CASTING CORE SYSTEM
(FR) SYSTÈME DE CORPS DE MOULAGE À MODÈLE PERDU
Abstract
(EN)
An investment casting core system includes first and second investment casting cores. The first investment casting core has a pin and the second investment casting core has a hole and an access slot that opens to the hole. The pin is disposed in the hole such as to space the first investment casting core in a fixed position relative to the second investment casting core. A bonding agent is disposed in the access slot and around the pin in the hole.
(FR)
Un système de corps de moulage à modèle perdu comprend des premier et second corps de moulage à modèle perdu. Le premier corps de moulage à modèle perdu a une broche et le second corps de moulage à modèle perdu a un trou et une fente d’accès qui s’ouvre vers le trou. La broche est disposée dans le trou de sorte à maintenir le premier corps de moulage à modèle perdu à une position fixe distante du second corps de moulage à modèle perdu. Un agent de liaison est disposé dans la fente d’accès et autour de la broche dans le trou.
