Filed:
Nov 6, 2009
Appl. No.:
12/614191

International Classification:
B29C 53/36
US Classification:
156217
Abstract:
A method of forming a seal ring includes heating an extruded rod to a temperature above a glass transition temperature. The extruded rod has first and second ends. The method further includes bending the extruded rod into a circular structure while the temperature is above the glass transition temperature, joining the first and second ends of the extruded rod to form a semi-finished ring, and annealing the semi-finished ring.
