Herzog Needle Type E (Elastomers) Shut Off Nozzle - Pneumatic Actuation

The field of application for the E-Nozzle is primarily LSR (Liquid Silicon Rubber).

In this nozzle‘s favour are:
• Targeted cooling or heating over the whole nozzle, i.e. tempering until the interface of nozzle – mould
• Compact concept
• Flexible connecting parts (tip, adapter)

There are multiple fields of LSR applications and is rising in importance. LSR molded parts are frequently observed in the automobile industry, home and sport components, pharmaceuticals, medicine and electronic industries.

More Information & Product Selection

Operation:
The herzog® E-Nozzle shows a very compact design. A 2-way pneumatic cylinder controls
the shut-off mechanism- while the integrated cooling system, which goes up to the
nozzle tip, ensures functional and reliable processing. The materials chosen in the production of the E-Nozzle are highly corrosion resistant.

Prevents:
• Vulkanisation of silicone in the nozzle
• Air pockets during screw retraction
• Material leakage when dosing with a withdrawn injection unit
• Material leakage while vertically injecting

Supported process control:
• Actuator piston position sensors (indicates if nozzle is “open” or “closed”)

Productivity factors:
• Controlled, clean shut-off of the melt stream
• No vulcanisation in the nozzle
• Increased process reliability and repeatability
• Add-on capability (on tool side)

Option:
• Process monitoring with piston position sensors on the actuator
