Due to the need to load and unload the mold, the movable cylinder on the vulcanizer will move in the upward and downward directions. After the copper serpentine tube reciprocates many times, fatigue fracture occurs, although it can be used after repair, but the parking repair will cause time loss. Although the rubber tube has good softness and strong anti-fatigue ability, it is also a weak link in terms of pressure, temperature resistance and anti-aging. It can not be continued after several months of use. The good overall performance of the metal hose is fully reflected here. In the general industrial field, in addition to pressure and temperature, there are often harsh conditions such as fatigue, corrosion, vibration, pressure, impact, etc. Under such circumstances, it is most suitable to compensate the positional movement of the pipeline.
