Advanced Manufacturing Process for Type T Oil Seal
The manufacturing of a high-quality Type T Oil Seal, such as the 9031150064, is a complex process demanding stringent quality control and advanced engineering. It's not just about forming rubber; it's about precise material compounding, intricate molding, and meticulous finishing. Our commitment to excellence ensures each seal meets the highest industry standards, including ISO 9001 for quality management and IATF 16949 for automotive quality management systems.
Manufacturing Process Flow for Type T Oil Seal
This process ensures the structural integrity, dimensional accuracy, and optimal sealing performance of every Type T Oil Seal.
- Material Compounding: Raw elastomers (e.g., HNBR, FKM), fillers (carbon black, silica), vulcanizing agents, accelerators, and processing aids are precisely weighed and mixed in internal mixers (Banbury mixers) or two-roll mills. This critical step determines the final physical and chemical properties of the seal, including its hardness, elasticity, temperature resistance, and chemical compatibility.
- Metal Case Stamping/Forming: High-grade carbon steel or stainless steel sheets are precision stamped or deep drawn to form the rigid outer metal case of the seal. This case provides structural rigidity, facilitates easy installation into the bore, and often houses the garter spring. CNC punching and bending machines ensure dimensional accuracy.
- Bonding Agent Application: The metal case undergoes thorough cleaning and surface treatment to ensure optimal adhesion. A specialized rubber-to-metal bonding agent is then applied to the metal case, which will chemically bond the elastomer to the metal during the molding process. This ensures a secure, leak-proof attachment.
- Pre-forming/Pre-shaping: The compounded rubber material is often pre-formed into slugs or blanks that match the approximate volume of the final seal. This step improves molding efficiency and reduces material waste.
- Molding (Compression or Injection):
- Compression Molding: The pre-formed rubber blank and the pre-treated metal case are placed into a heated mold cavity. The mold is closed, and pressure is applied, forcing the rubber to flow and fill the cavity while simultaneously vulcanizing (curing) and bonding to the metal insert. This is a common method for seals.
- Injection Molding: For higher volume and more complex geometries, rubber granules are melted and injected under high pressure into a closed, heated mold cavity containing the metal case. This method offers faster cycle times and consistent part quality.
- Deflashing and Trimming: After molding, excess rubber material (flash) that forms along the mold parting lines is removed. This can be done manually, cryogenically (using liquid nitrogen to make the flash brittle for easy removal), or via automated trimming machines. Precision trimming is essential for optimal sealing performance and aesthetics.
- Garter Spring Insertion: For seals requiring radial lip force, a precisely wound spring (typically carbon steel or stainless steel) is inserted into the groove behind the primary sealing lip. The spring maintains constant contact between the sealing lip and the shaft, compensating for wear and temperature fluctuations.
- Post-Curing (Optional but Recommended for FKM/HNBR): Some materials, especially FKM and HNBR, benefit from a post-curing process in an oven. This additional heating stage helps to fully cross-link the polymer chains, enhancing the seal's long-term mechanical properties, chemical resistance, and thermal stability.
- Quality Inspection & Testing: Each Type T Oil Seal undergoes rigorous quality control. This includes:
- Visual Inspection: Checking for surface defects, flash, and overall appearance.
- Dimensional Measurement: Using precision calipers, micrometers, and optical measuring systems to ensure compliance with specifications (e.g., ISO 3601 for fluid power seals, DIN standards).
- Material Property Testing: Random samples are tested for hardness (Shore A), tensile strength, elongation at break, compression set, and specific gravity.
- Functional Testing: Leakage tests, friction torque tests, and accelerated life tests on specialized rigs simulate real-world operating conditions to confirm performance (e.g., according to ASTM D6616 or ISO 6194).
- Automated Optical Inspection (AOI): High-speed cameras and image processing software identify microscopic defects or variations.
- Packaging and Dispatch: Finished seals are cleaned, inspected, and carefully packaged to prevent damage during transit. Proper labeling ensures traceability and correct product identification for our clients globally.
