4. Surface Treatment & Bonding: The metal housing often undergoes surface treatments such as phosphating or anti-corrosion coatings to enhance its durability and prepare it for bonding. A strong, durable bond between the elastomer and the metal housing is achieved using specialized adhesives and controlled bonding processes (e.g., vulcanization bonding), ensuring no delamination occurs during operation.
5. Garter Spring Insertion: The garter spring, often made of spring steel, is precisely manufactured to provide the specified radial load on the sealing lip. It is then carefully inserted into the elastomer lip, a critical step for maintaining consistent sealing contact.
6. Assembly: The various components – metal housing, elastomeric elements, and garter spring – are precisely assembled. Automated assembly lines ensure high throughput and consistent quality.
7. Quality Control & Testing: Each batch undergoes rigorous quality control checks. This includes dimensional verification using optical comparators and CMMs, material hardness testing (Shore A), visual inspection for defects, and functional tests such as leak testing under various pressure conditions and durability tests on test benches simulating real-world operating conditions (e.g., accelerated wear tests, high-temperature cycling). Adherence to international standards like ISO 6194-1/2 (Rotary shaft lip type seals) and ANSI standards ensures consistent performance.
8. Packaging & Dispatch: Seals are carefully packaged to prevent damage during transit and stored in controlled environments to maintain material integrity until dispatch.

This detailed process, from raw material selection to final testing, underscores the commitment to producing seals with exceptional energy saving properties through reduced friction, high corrosion resistance, and an extended service life crucial for target industries like agriculture, petrochemical, metallurgy, and heavy construction.
