METHOD OF FORMING LARGE DIAMETER THERMOPLASTIC SEAL |
摘要 |
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.
