Features:
Compared with conventional horizontal single-pitch hydraulic bellows forming machines, this equipment delivers improved forming accuracy, better surface finish, and more consistent product quality. It ensures higher repeatability and stability during continuous production.
Bellows produced by our muti-pitch bellow forming machine
Metal bellows manufactured by our multi-pitch forming machine are widely used as precision components in various industries, including automatic control systems, instrumentation, vacuum technology, mechanical engineering, power generation, transportation, and nuclear energy applications.
They serve critical functions such as vibration damping, expansion compensation, sealing, valve integration, and pipeline connection, ensuring reliable performance under complex working conditions.
Metal bellows feature a uniform corrugated structure and typically consist of a flexible bellows section combined with end connection components. This design allows them to effectively accommodate axial, lateral, and angular movements.
They are especially suitable for applications involving:
With excellent flexibility, durability, and sealing performance, metal bellows are an essential solution for modern industrial piping and control systems.




We specialize in flexible metal hose machinery with many years' experience and develop our machine technology all the time. So far, we have exported our machinery to many countries, such as US, Canada, Turkey, Australia, UK, Russia, Ukraine, India etc.
