- positioning an insert in a vertical mold comprising a first mold portion and a second mold portion;
- and
- casting a material comprising a metal around at least a portion of the insert and wherein the insert comprises at least one tab comprising a bent tab portion.
A method comprising:
- providing an insert comprising at least one bent tab portion;
- and
- positioning 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.
A method comprising:
- loading an insert into a setting fixture;
- and
- using the setting fixture to load the insert into a first mold portion of a mold for casting metal.
A method comprising:

- and
- at least one gate positioned at the bottom of the vertical mold, wherein the cross-sectional area of the gate is large enough to avoid turbulent flow of molten material comprising a metal through the gate.
A method comprising:
- pre-heating an insert before placing the insert into a setting fixture;
- loading the insert into the setting fixture, wherein the insert comprises a body portion and a plurality of tabs each comprising a bent tab portion;
- using the setting fixture to load the insert into a first mold portion of a vertical mold;
- positioning the insert in the first mold portion of the vertical mold using the bent tab portion of the insert to at least partially assist in holding the insert in place in the first mold portion;
- closing the first mold portion and a second mold portion of the vertical mold together;
- and
- casting a material comprising a metal over at least a portion of the insert to form a part, wherein the casting comprises pouring the material into at least one gate located in the bottom of the vertical mold, wherein only one gate is positioned in between two adjacent tabs.
