Dual-column Non-Vibration Screen Changer: It can be said that the screen changer has been reinvented. Its invention will make the original single-column screen changers obsolete, as the core value of this screen changer is, with the same cylindrical structure, it offers over four times the filtering area, yet functions completely differently, ensuring high-pressure non-leakage. The screen change is more convenient, with no fluctuations or blind spots, and can automatically extend with pressure control during screen change. After automatic filling, it can also automatically exhaust air, completely without affecting the extruder's continuous operation or the quality of the extruded product. It can be used on any extruder equipment such as blowing film machines, drawing machines, packaging tape machines, pipe material machines, granulating machines, and fiber spinning equipment without interruption and without waste.
