Germany technology steel wire combing machine For steel wire combing machines, we have all germany technology machines, which is much less length tolerance than old machine. According to SAE J517 standard of hydraulic hose, the steel wire length tolerance is 10XN, which means the lenght tolerance is 10 times of numbers of steel wire. For example, if the combining steel wire is 8 wires, the tolerance should be less 10X8, which equal 80cm. It is standard numbers, but in reality of braiding , it results extra wire coil on brading surface, then the workers have to cut it , finally it makes connnection on brading net. When the hydraulic hose with steel wire connnection, the working pressure will be less and impulse can not reach standard. But the Germany technology steel wire combing machine reduce length tolerance too much, so it is no any steel wire connections in reforcement of hydraulic hose, that is quality , but you can NOT see from the surface of hydraulic hose. There more difference in other productions steps. One word, it is right choice for you to select us as your reliable supplier of hydraulic hose, rubber hose.
