A new accessory can turn standard nozzles into self-actuating shutoffs. The 160-oz-capacity shutoff provides versatility by eliminating the need for single-purpose nozzles. Installed between the nozzle body and tip, the shutoff can eliminate drool or stringing. The H-13 tool steel unit is suited to handle high operating temperatures and packing pressures. An internal spring and piston block off the melt as the nozzle tip withdraws from the mold. The shutoff device measures 4 inches and uses a standard female thread.
