The shut-off nozzle is a critical component for making the microcellular process work. The shut-off nozzle must be closed during all phases of the injection molding cycle except for injection and hold. To ensure this, the nozzle should be positively actuated to close. The shut-off nozzle is kept closed as 1) an open nozzle would allow the SCF
