Needle Type Pneumatic Shut Off Nozzle

Introduction Needle type pneumatic shut-off nozzle mainly serves to solve the leakage of low-density thermoplastic injection process, like PA, PP, PS, PE, POM, also it’s suitable in high frequency process, and used on high speed injection synchronization, which can improve production efficiency, shorten production time and save cost. Mechanism During storage period of injection unit process, through integrated air 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.
