Precision Manufacturing Process of **70×90×7 Cfw Oil Seal 70907 Tcv Rubber High Pressure FKM NBR oil seal**

The manufacturing of a high-performance seal like the 70×90×7 Cfw Oil Seal 70*90*7 Tcv Rubber High Pressure FKM NBR oil seal involves a meticulous, multi-stage process that ensures precision, material integrity, and consistent quality. This process combines advanced material science with sophisticated engineering and manufacturing techniques.

Step 1: Material Compounding

High-quality FKM or NBR raw polymers are precisely mixed with reinforcing fillers, curing agents, plasticizers, and other additives in internal mixers. This crucial step determines the final physical and chemical properties of the rubber compound, such as hardness, tensile strength, elasticity, and resistance to specific media and temperatures. Adherence to ASTM D2000 standards ensures consistent material properties.

Step 2: Metal Case Preparation

For seals with a metal case (common for CFW type seals), high-grade steel sheets are precision-stamped or deep-drawn to form the outer shell. This provides structural integrity and ensures a secure press fit into the housing. Surface treatments like phosphating or rubber-to-metal bonding agents are applied to enhance adhesion with the elastomer.

Step 3: Molding (Compression/Injection)

The compounded rubber is then pre-formed and placed into precision molds. Using either compression molding for simpler designs or injection molding for more complex geometries and higher volumes, the rubber is heated and pressed against the metal case (if applicable) under high pressure. This forms the seal's critical sealing lip(s) and outer body. The TCV profile, known for its high-pressure capabilities, is precisely formed at this stage.

Step 4: Curing/Vulcanization

After molding, the seals undergo a critical curing or vulcanization process. This involves heating the molded parts to a specific temperature for a defined period, which cross-links the polymer chains. This process transforms the soft rubber into a stable, elastic, and durable elastomer, giving it its final mechanical properties and ensuring long-term performance and low compression set.

Step 5: Trimming and Finishing

Excess rubber material (flash) is precisely removed from the seals using automated trimming machines or cryogenic deflashing techniques. This ensures clean edges and precise dimensions, particularly around the sealing lip, which is critical for optimal sealing performance and reduced friction.

Step 6: Spring Insertion (if applicable)

For seals featuring a garter spring (common in CFW designs), the spring is precisely inserted into the groove behind the sealing lip. This spring provides a constant radial force, ensuring continuous contact between the sealing lip and the shaft, which is vital for maintaining a tight seal, especially at higher pressures and speeds.

Step 7: Quality Control and Testing

Each batch of 70×90×7 Cfw Oil Seal 70*90*7 Tcv Rubber High Pressure FKM NBR oil seal undergoes rigorous quality checks. This includes dimensional inspection (using CMMs or optical comparators), visual inspection for defects, material property testing (hardness, tensile strength, elongation), and functional tests (leakage tests, friction torque, and accelerated aging tests). Seals must meet strict international standards like ISO 6194 and ANSI B92.1, ensuring consistent performance and reliability. Lifespan testing simulates operational conditions to validate long-term durability.

Step 8: Packaging and Dispatch

Finished seals are carefully packaged to prevent damage during transit, ensuring they arrive in pristine condition. Proper labeling includes batch numbers and material specifications for traceability.
