Abstract
Official abstract text for this publication.
Disclosed are a method of casting heterogeneous materials and a casting produced manufactured by the same. The method may include disposing a lost foam on a cavity of a mold as the cavity being formed in a shape corresponding to a shape of a casting product; injecting a first molten metal through a low-pressure molten metal ingate formed in the mold to form a low-pressure casting portion of the casting product; and injecting a second molten metal through a gravity molten metal ingate formed in the mold to form a gravity casting portion of the casting product.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a casting product comprising heterogeneous materials, comprising: disposing a lost foam on a cavity of a mold, the cavity being formed in a shape corresponding to a shape of a casting product; injecting a first molten metal into the mold through a low-pressure molten metal ingate formed in the mold to form a low-pressure casting portion of the casting product; and injecting a second molten metal into the mold through a gravity molten metal ingate formed in the mold to form a gravity casting portion of the casting product. 2. The method according to claim 1 , wherein the first molten metal for the low-pressure casting portion and the second molten metal for gravity casting portion are different from each other in their material compositions thereof. 3. The method according to claim 1 , wherein a point of time when the injected first molten metal for the low-pressure casting portion reaches the lost foam is same as a point of time when the injected second molten metal for the gravity casting portion reaches the lost foam. 4. The method according to claim 1 , wherein an interface formed by joining of the first molten metal for the low-pressure casting portion and the second molten metal for the gravity casting portion is formed at a position where the lost foam is disposed. 5. The method according to claim 1 , further comprising disposing a core in the cavity.
