摘要：
A method for investment casting includes the steps of positioning a base plate (12) relative to a die; molding a first material between the die and at least a first surface portion of the base plate (12); securing one or more patterns (22) to the base plate, the one or more patterns (22) comprising a second material; applying one or more coating layers over at least portions of the one or more patterns (22) and at least a portion of the first material; substantially removing the first material through an interior receptacle (28) of a manifold body (16) and the second material through an exterior receptacle (30) of the manifold body (12) to leave one or more shells (22) formed by the coating layers; introducing molten metal to the one or more shells through the interior receptacle (28) of the manifold body (16); permitting the molten metal to solidify; and destructively removing one or more investment casting molds.
