NEEDLE SHUT OFF VALVE NOZZLE PNEUMATIC HYDRAULIC FOR INJECTION MOLDING MACHINE
Model: RN-I, RN-II, RN-III
Category: Plastic Injection Molding Machine
Exhibitor: NINGBO ROOTIER INDUSTRY AND TRADE CO., LTD.
Booth No: B525
Characteristic
Application:Injection Molding
Function:Prevent Leakage, Shorten Cycle Time
Suitable Machine:60T-2000T
Max. Injection Pressure:3000Bar
Needle lever shut-off nozzle mainly serves to solve the low viscosity thermoplastic leakage, or to shorten injection cycle time by screw dosing while mould opening, which widely used on high speed injection synchronization and prevent wire-drawing.
Drive can be pneumatic or hydraulic depends on machine convenient.
Mechanism
During storage period of injection unit process, through integrated air or hydraulic cylinder, the inside needle is pushed in axial direction to seal inside nozzle and keep lock-up, so that material won’t pass and leak. And open with machine signal to offer precise injection. During synchronization process, the screw can melt polymer the same time mold opens and save precious time.
