Manufacturing Process Flow of the AP4212B TCN Oil Seal

The production of a high-performance oil seal like the Pump seal AP4212B TCN oil seal 110-140--14 involves a meticulously controlled, multi-stage process to ensure consistent quality and adherence to stringent technical specifications. Our commitment to precision engineering underpins every step.

Process Steps:

1
Material Selection & Preparation: Selection of high-grade NBR (Nitrile Butadiene Rubber) for its excellent resistance to petroleum-based oils and greases, coupled with good abrasion resistance. For more aggressive environments, FKM (Fluoroelastomer) or HNBR (Hydrogenated Nitrile Butadiene Rubber) options are available upon request for enhanced chemical and heat resistance. Raw materials undergo rigorous quality checks conforming to ASTM D2000 standards for polymer classification.
2
Metal Case Stamping/Forging: The robust outer metal case, providing structural integrity and interference fit, is typically manufactured from carbon steel (e.g., SAE 1010-1020) through precision stamping or cold forging. This process ensures dimensional accuracy and prevents deformation under operational stress.
3
Elastomer Molding (Compression/Injection): The prepared rubber compound is then molded onto the metal case. Compression molding or injection molding techniques are employed, depending on design complexity and volume, to create the precise lip profile and sealing element. Critical parameters like molding temperature, pressure, and cure time are strictly controlled to ensure optimal material properties and minimize flash.
4
Spring Insertion: For TCN (Double Lip with Spring) type seals, a garter spring made from high-tensile spring steel (e.g., SUS304 or carbon steel, depending on environment) is precisely inserted into the lip to maintain constant radial force against the shaft, ensuring a consistent seal over its operational life.
5
Trimming & Finishing: Excess material (flash) is removed, and seals undergo a final cleaning process.
6
Quality Control & Testing: Each batch undergoes rigorous testing to ISO 6194-1/2, DIN 3760, and ANSI B92.1 standards. This includes dimensional checks, material hardness (Shore A), tensile strength, elongation, compression set, and accelerated life testing under simulated operating conditions (e.g., high temperature, dynamic shaft rotation, pressure cycling). Leakage rates are meticulously monitored to ensure zero tolerance.

Target industries benefiting from this seal's robust design include petrochemical, metallurgy, mining, water supply & drainage, and general industrial pumping. Its design prioritizes advantages such as energy saving through minimized friction, superior corrosion resistance due to material selection, and extended service life up to 10,000 hours in typical application scenarios, significantly reducing total cost of ownership (TCO).
