    摘要: A slurry is used to secure a metallic casting core (212) to a ceramic casting core (210). The slurry may be introduced between the metallic and ceramic casting cores (212,210) and hardened. The slurry may comprise zircon and aqueous colloidal silica. Preferably the cores (210,212) are vibrated during the introduction, e.g. by a shaker table (202) which receives a fixture (204) for the cores (210,212).

    摘要: A pattern (20) with internal cores for creating a hollow component is composed of a first pattern half (10) having one or more first self-locating features (12); a second pattern half (16) having one or more second self-locating features (18); and one or more cores (14) disposed in contact with the one or more first self-locating features (12) and the one or more second self-locating features (18). The method for its manufacture includes the steps of creating a first pattern half (10) having one or more first self-locating features (12); creating a second pattern half (16) having one or more second self-locating features (18); providing one or more cores (14); and assembling the pattern (20) by engaging the one or more first self-locating features (12) and the one or more second self-locating features (18) about the one or more cores (14).
