Manufacturing Process Flow: Ensuring Quality in Every Oil Cooler Hose

The production of a high-quality Olíukælislanga SAE J1532 is a sophisticated process that integrates advanced material science with precision engineering. Each step is meticulously controlled to ensure the final product meets or exceeds the rigorous demands of the SAE J1532 standard and application requirements.

1. Material Preparation: High-grade synthetic rubber granules (NBR, HNBR for inner tubes; EPDM, CSM for covers) and textile fibers are carefully selected and compounded. This critical stage involves precise mixing to achieve the desired physical and chemical properties, including oil resistance, heat aging resistance, and elasticity.
2. Inner Tube Extrusion: The compounded inner tube material is fed into an extruder, where it is heated and forced through a die to form a seamless tube of precise internal diameter and wall thickness. Consistency here is vital for fluid flow and pressure integrity.
3. Reinforcement Layer Application: The extruded inner tube is then transferred to a braiding or spiraling machine. High-tensile synthetic yarns (e.g., polyester, aramid) are helically wound or braided around the inner tube. This step provides the necessary burst strength and prevents kinking or collapse. The number of plies and tightness of the weave are engineered for specific pressure ratings.
4. Outer Cover Extrusion: A second extrusion process applies the protective outer cover layer over the reinforced inner tube. This cover is formulated to provide superior resistance to environmental factors such as ozone, UV radiation, abrasion, and incidental chemical splashes.
5. Curing (Vulcanization): The constructed hose is then subjected to a controlled heating process (vulcanization). This chemical process cross-links the rubber molecules, permanently setting the hose's physical properties, enhancing its elasticity, durability, and resistance to heat and chemicals. This is often done in an autoclave or continuous curing line.
6. Finishing and Marking: After curing, the hose is cooled, cut to specified lengths, and marked with essential information such as manufacturer's name, part number, batch code, and compliance standards (e.g., "SAE J1532").
7. Quality Control and Testing: Each batch undergoes rigorous testing to validate compliance with SAE J1532 and internal quality benchmarks. Tests include:
   • Dimensional checks (ID, OD, wall thickness)
   • Burst pressure testing (to 4x MWP)
   • Proof pressure testing
   • Adhesion testing between layers
   • Cold flex testing
   • Oil resistance and volume swell tests (per SAE J1532 Section 7.2)
   • Ozone resistance (ASTM D1149)
   • Temperature cycling and impulse testing (for dynamic applications)

This methodical approach, underpinned by ISO 9001 certified manufacturing practices, ensures that every Olíukælislanga SAE J1532 delivered offers exceptional reliability and performance, meeting the stringent demands of industries like petrochemical, metallurgy, and heavy machinery.
