    Unscrewing system is common used in Mold structure for product with deep threads, Drive by motor and by hydraulic cylinder are the two main ways of unscrewing system, then what’s the difference and which situtation use motor which situation use hydraulic cylinder?

      Hi boss, it should depend on the bottle & cap fitting requirement! If it has the fixed location requirement, then need cylinder to control the exact location you want! If no, then use motor will be ok!

Your good choice to have the quality mold in China!
