Abstract
A method of forming a rotor by forming a mold by forming a first mold cake, a second mold cake, and a core that fits between the first and the second mold cake. The method includes a step of locating the core between the first mold cake and the second mold cake. The core includes a body, one or more projections extending from the body for forming one or more holes in a base portion of the rotor, and one or more projections extending from the body for forming one or more holes in a bat wall of the rotor.
Claims20
A method of forming a rotor comprising:
- forming a mold by:
- forming a first mold cake;
- forming a second mold cake;
- forming a core that fits between the first mold cake and the second mold cake;
- and
- locating the core between the first mold cake and the second mold cake;
- wherein the core includes:
- a core body;
- one or more projections extending from the core body for forming one or more holes in a base portion of the rotor;
- and
- one or more projections extending from the core body for forming one or more holes in a hat wall of the rotor;
- wherein the one or more projections for forming the one or more holes in the base portion and the one or more projections for forming the one or more holes in the hat wall are located at an angle relative to each other;
- wherein the one or more holes in the base portion and the one or more holes in the hat wall are in an aligned relationship;
- wherein the rotor comprises a two-sided braking surface, the base portion attaches the two-sided braking surface to the hat wall, and the base portion is located in a plane that is generally parallel to at least one of the sides of the two-sided braking surface.
