Abstract: An at least two step heating process is used to strengthen the shell of an investment casting mold including a refractory metal core. The first stage (46) may occur under otherwise oxidizing conditions at a low enough temperature to avoid substantial core oxidation. The second stage (56) may occur under essentially non-oxidizing conditions at a higher temperature.

Abstract: La presente invención describe un proceso de fusión a la cera perdida, en donde se forma un núcleo compuesto como una combinación de un elemento de núcleo de fusión cerámico y un elemento de núcleo de fusión no cerámico. El núcleo se calienta en una atmósfera oxidante y luego se calienta en una atmósfera no oxidante.

Abstract: An apparatus for shelling an investment casting pattern (22) has a tank (26) containing a coating material (28). There are means for holding the pattern immersed in the coating material. There may be means for vibrating the pattern during immersion of the pattern and a vacuum source (126) coupled to the tank to withdraw air from at least one headspace (79) of the tank.

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