Hebei Chengen Huanbao Technology Co., Ltd. follows a highly precise and comprehensive brake hose manufacturing process. The process begins with the selection of top - grade raw materials. High - quality rubber compounds, which are carefully formulated to provide excellent flexibility, resilience, and chemical resistance, are chosen as the base material for the hose. Reinforcing materials, such as high - tensile - strength steel wire or synthetic fibers, are also selected for their ability to withstand high pressure. The first step in production is the extrusion of the rubber compound into a hose - like shape. Then, the reinforcing layer is applied around the extruded rubber, either through a braiding or winding process, to enhance the hose's pressure - bearing capacity. After that, the hose undergoes a vulcanization process, where it is heated under pressure to cross - link the rubber molecules, improving its mechanical properties and durability. Subsequently, the ends of the hose are fitted with high - quality fittings through a crimping process, ensuring a secure and leak - proof connection. Finally, each brake hose is subjected to a series of strict quality tests, including pressure testing, burst testing, and aging tests, to ensure that it meets the highest standards of safety and performance before being approved for sale and distribution.
