Specially Engineered Shut-Off Nozzles
Save material by eliminating drooling, stringing, and leakage with SFP's Herzog® Shut-Off Nozzles. They offer Increased reliability, reduction in waste parts and cycle times. Choose the smarter option, SFP's Herzog® Shut-Off Nozzles.
BHP   Bolt Shut-Off Nozzle - Type BHP
• Shearing of the material can reduce cycle times by dosing the next shot sooner while at the same time preventing drooling.
• Controlled by either pneumatic or hydraulic actuators, its carefully developed design allows for the easiest of installations and it can be adapted to any injection molding machine.
• Max. injection rate: 5,000 cm3/s

• Max. injection pressure: 3,000 bar at 400°C.

HP   Needle Shut-Off Nozzle - Type HP
• Separates the melt stream directly at the mold interface.
• Ideally suitable for closing against high pressures and remaining closed regardless of back pressure.
Max. injection rate: 3,500 cm3/s
Max. injection pressure: 3,000 bar at 400°C

A   Needle Shut-Off Nozzle - Type A
Strong, reliable and above all economical, it can be adapted to any machine type with the simplest of installations.
• Nozzle operation is melt pressure dependant. The axial aligned needle is held in the closed position by spring force. Once the injection pressure rises above 200 bar, it will overcome the spring force and open the nozzle.
Max. injection rate: 1,600 cm3/s
Max. injection pressure: 2,000 bar at 350°C

SHP   Needle Shut-Off Nozzle - Type SHP
• Specially designed for processors who require an uncomplicated shut-off while operating at high temperatures
and high pressures.
• Compact design is effortless to install and can be expanded with a low pressure drop screen type filter.
Max. injection rate: 500 cm3/s
Max. injection pressure: 3,000 bar at 400°C

NE   Needle Shut-Off Nozzle - Type NE
• Specifically designed for use in elastomer processing.
• Rubber, liquid silicone rubber, and other elastomers can be processed without fear of
vulcanization due to the nozzle’s integrated cooling system which uniquely regulates
temperature throughout the entire nozzle.
• Manufactured from corrosion resistant
materials.
Max. injection rate: 500 cm3/s
Max. injection pressure: 3,000 bar at temperature range –20°C to 110°C

TSN   Needle Shut-Off Nozzle - Type TSN
• Used in the processing of thermoplastics, principally with low viscosity materials such as: PA, PPS, PE, POM, PP.
• Max. injection rate: 500 cm3/s
• Max. injection pressure: 3,000 bar at temperature range –20°C to 110°C
