The production materials for automotive hoses mainly include rubber and reinforced skeleton materials. Among them, the choice of reinforced skeleton materials is crucial for the performance of the hoses. Para-aramid fibers are the preferred reinforced skeleton material due to their high strength, high modulus, lightweight, and excellent chemical resistance and material stability. The para-aramid fiber solutions provided by Sinochem International can significantly enhance the performance of hoses, especially in high-pressure hoses and those requiring high resistance to pulse vibrations, effectively improving product performance and extending product lifespan to reach the level of similar foreign products.
To address issues that arise during the production of hoses, such as uneven end faces, bending, twisting, and loss of roundness, production processes can be optimized. For example, controlling the cutting process, using a reasonable water injection method, and adjusting the heating and pressurization rates of the equipment can effectively reduce these problems and improve product quality.
The aramid fiber solution follows the quality process management standards of IATF16949 and VDA6.3, and custom product development is carried out according to APQP specifications. In addition, Sinochem International also has a CNAS certified testing center, which can provide industry-authoritative product testing reports to ensure that product quality meets international standards.
In the automotive cooling system hoses, using para-aramid as the reinforcement skeleton material can operate normally for a long time under working conditions from -196℃ to 204℃, significantly enhancing the performance and stability of the cooling system hoses.
To address issues such as hose bursting and cracking, solutions can be implemented by enhancing material strength, improving metal component design, and adjusting hose formulations. For example, measures such as increasing the diameter of the wire rope and optimizing the design of metal components can effectively improve the pressure resistance and burst pressure of the hose, reducing the risk of bursting and cracking.
