Pneumatic shut-off nozzle is commonly used in injection molding, such as microcellular injection molding, and high-speed injection.Main advantages:
(1) Prevent glue overflow, injection drawing, casting, overflow, cold glue, leakage, etc.
(2) Improve injection molding speed with a high back pressure, shorten molding cycle.
(3) Maintain the high-pressure state inside the nozzle, control the pressure drop when the melt flows through the nozzle, and meet the requirements of micro hole injection molding and micro foaming processes.
