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. |
|
|
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. |
|
|
|
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 |
|
|
|
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 |
|
|
|
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 |
|
|
|
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 |
|
|
|
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 |
