초록

A method including positioning an insert in a vertical mold including a first mold portion and a second mold portion; and casting a material including a metal around at least a portion of the insert.

대표청구항 ▼

1. A method comprising: positioning an insert in a vertical mold comprising a first mold portion and a second mold portion; andcasting a material comprising a metal around at least a portion of the insert and wherein the insert comprises an annular body portion having an inner edge and an outer edge, the annular body having a flat portion extending radially, and a tab having a portion extending radially inward from the inner edge or outward from the outer edge, and the tab having a portion extending radially being parallel to the flat portion, and wherein the tab comprises a bent tab portion. 2. A method as set forth in claim 1 further comprising pre-treating the insert before positioning the insert in the vertical mold. 3. A method as set forth in claim 2 wherein the pre-treating comprises at least one of sand blasting, grit blasting, glass bead blasting, chemical washing, or water jet degreasing. 4. A method as set forth in claim 1 further comprising coating the insert before positioning the insert in the vertical mold. 5. A method as set forth in claim 4 wherein coating the insert comprises at least one of spraying, dipping, or painting. 6. A method as set forth in claim 4 further comprising baking the insert. 7. A method as set forth in claim 4 further comprising preventing the casting of the material around the insert from washing away the coating. 8. A method as set forth in claim 1 further comprising pouring the material into the vertical mold so that the metal is filled from the bottom of the mold up. 9. A method as set forth in claim 8 further comprising pouring the material into at least one gate located at the bottom of the vertical mold. 10. A method as set forth in claim 9 wherein the insert comprises at least two tabs and wherein only one gate is positioned in between two adjacent tabs. 11. A method as set forth in claim 8 wherein the flow rate of the material poured into the vertical mold is such that turbulent flow is avoided. 12. A method as set forth in claim 1 further comprising a layer comprising at least one of particles, flakes, or fibers over a portion of the insert. 13. A method as set forth in claim 1 further comprising treating at least a portion of the insert so that molten material comprising a metal does not wet the portion of the insert and bond thereto upon solidification. 14. A method comprising: providing an insert comprising at least one bent tab portion; andpositioning the insert in one of a first mold portion or a second mold portion of a vertical mold using the bent tab portion of the insert to at least partially assist in holding the insert in place in a vertical position wherein the bent tab portion hangs on and is supported by the first mold portion or the second mold portion. 15. A method comprising: loading an insert into a setting fixture, the insert comprising an annular body portion having a flat portion extending radially, and a tab extending radially inward or outward from the flat portion and wherein the tab comprises at least one bent tab portion; andusing the setting fixture to load the insert into a first mold portion of a mold for casting metal. 16. A method as set forth in claim 15 wherein the setting fixture comprises a vacuum component. 17. A method as set forth in claim 15 wherein the setting fixture comprises at least one ejector pin.
