Standard hot-runner nozzles

Hot-runner nozzles

GÜNTHER offers a line of nozzles to meet the demands of modern day injection mould technology with a variety of melt channel diameters, nozzle lengths and gate geometries.

The different nozzle types, whether as a single nozzle or for multi-tip gating, allow you to realize any number of applications. Based on the modular design, individual parts, such as the heating element, sensor, material tube and nozzle tips, can be replaced. This offers great advantages when performing repairs and maintenance work (time savings, lower repair costs, less downtime).

The GÜNTHER standard hot-runner nozzles will sell themselves with their outstanding thermal separation afforded by the two-component shaft. This will ensure excellent insulation in the front shaft area and thus very little heat loss between the hot runner nozzle and the cavity. These nozzles are suitable for processing of heat sensitive materials, technical plastics, and high temperature polymers. With filled materials, such as glass fibres with heat stabilizers, wear-resistant heat conductor tips provide the best possible protection against mechanical and chemical attack. Standard hot-runner nozzles are available in the CADHOC® database.


  • Optimum temperature transition thanks to the large contact surfaces between the heat conducting tip and the heated material tube.
  • Reduction of the processing temperature thanks to the excellent thermal conduction of the nozzle tips. No loss of heat, since there is no contact with the mould.
  • Easy mounting and protection against leaks as well as less time spent on installation and removal.
  • Time savings and reduced tool costs due to the easy H7 geometrical fit.
  • Outstanding insulation at the front of the nozzle due to the two-component shaft, thus very little heat loss between nozzle and cavity.
  • Excellent gate quality, due to the advantageous heat transfer at the gate position.
  • Wide range of processing temperatures, since the temperature profile is linear
  • Easy-to-install, plug-in power and thermocouple connections make assembly and disassembly easy.
