Abstract
One exemplary embodiment includes a method that calls for supporting an insert in a mold cavity of a casting die by way of one or more spacers, introducing a molten material into the mold cavity such that the one or more spacers are melted and consumed by the molten material, and wherein the one or more spacers and the molten material are of the same composition.
Claims18
A method comprising:
- supporting an insert in a mold cavity of a casting die by way of one or more spacers;
- and
- introducing a molten material into the mold cavity such that the one or more spacers are melted and consumed by the molten material;
- wherein the one or more spacers and the molten material are of the same composition.
1 more element
A method comprising:
- providing a casting die having a mold cavity shaped for casting a brake component;
- supporting at least one insert in the mold cavity with one or more spacers of a first composition;
- and
- casting a brake component in the mold cavity around the at least one insert using a molten material of the first composition.
1 more element
A method comprising:
- providing a sand casting die that includes an upper die member and a lower die member that, when closed, define a mold cavity shaped for casting a brake component;
- supporting at least one insert in a predetermined relationship to the mold cavity by way of one or more spacers comprising a first composition;
- introducing a molten material comprising the first composition into the mold cavity;
- melting gradually the one or more spacers in the molten material while maintaining the predetermined relationship between the at least one insert and the mold cavity;
- and
- solidifying the molten material around the insert and into a brake component of uniform composition.
