Abstract
Official abstract text for this publication.
A number of variations may include at least one mold portion that may define a first cavity, a circular gating system, and at least one sprue. The circular gating system may surround the first cavity and define a continuous in-gate from the circular gating to the first cavity. The at least one sprue and at least one vent may be in fluid communication with the circular gating system and the first cavity.
First claim
Opening claim text (preview).
What is claimed is: 1. A product comprising: at least one mold portion defining a first cavity, the first cavity being generally tubular in shape and having an outer circumference opposite an inner circumference, a circular gating system, and at least one sprue, the circular gating system surrounding the outer circumference of the first cavity and defining a continuous in-gate from the circular gating system to the first cavity, and the at least one sprue and at least one vent being in fluid communication with the circular gating system and wherein the at least one vent is disposed on the inner circumference of the first cavity. 2. A product as set forth in claim 1 , wherein the first cavity defines a squirrel cage rotor cavity. 3. A product as set forth in claim 1 , wherein the at least one mold portion includes a second mold portion that may further define the first cavity, the circular gating system, the at least one sprue, and the at least one vent. 4. A product as set forth in claim 1 , wherein the at least one mold portion further defines at least one biscuit. 5. A product as set forth in claim 1 , wherein the at least one mold portion further defines a choke in fluid communication with the sprue. 6. A product as set forth in claim 1 , wherein the first cavity includes a plurality of lamina cavities disposed between a first end ring cavity and a second end ring cavity in fluid communication with the circular gating system. 7. A product as set forth in claim 1 , wherein the at least one mold portion further defines at least one vent or overflow having a generally kidney shape.
