Hot runner nozzles for lateral injection

Hot runner nozzles for lateral injection – optimum freedom

GÜNTHER offer both radial and linear multi-drop hot runner nozzles. Optimum freedom for designing hot runner systems with minimal cavity spacing is made possible by using type SGF/SGT multi-drop hot runner nozzles.

With their type SGF/SGT multi-drop hot runner nozzles, GÜNTHER Hot Runner Technology has developed a series which ensures optimum freedom for designing your hot runner systems. This nozzle series is ideal for the multi-drop injection of small parts with minimal cavity spacing. Thanks to their flexibility and ability to adapt to complex requirements, type SGF/SGT series nozzles are able to fulfil the highest requirements on the gate position, vestige quality and shot weight

The advantages

  • Simple mould design
  • Small cavity spacing
  • Tips can be controlled individually
  • Also for micro-injection moulding machines

Another advantage for your applications:

The temperature of the nozzles can be controlled separately for each tip. The nozzles allow for a gentle flow of molten plastic and enable the use of compact moulds with a high number of drops on micro-injection moulding machines.

 

Hot runner nozzles for side gating

Hot runner nozzles for side gating – a perfect solution

A perfect solution for side gating is the OktaFlow® hot runner nozzle, which enables up to eight tips to be used for each nozzle.

Guaranteed free of problematic production-related “cold slugs”, the especially cost-effective and spacesaving multi-drop nozzles of the radial and linear OktaFlow® series ensure direct side gating.

The advantages

  • Side gating under 90°
  • Small cavity spacing
  • High number of cavities
  • No complex, split insert necessary
  • Longitudinal expansion via feed nozzle, installation of the sub-manifold independent of the heat expansion
  • Optimal temperature profile
  • Exchangeable nozzle tips
  • Installation-friendly plug-in type power and thermocouple plug connections
  • Reduced contoller technology requirements

Both versions have the same features:

  • They can be used in combination with a heated nozzle adapter or a manifold for injection moulding tools with a high number of drops.
  • For the processing of filled materials, nozzle tips with wear protection can be used instead to ensure long service lives in continuous operation.
  • The tips can be changed individually.

 

Multi-drop hot runner nozzles for side gating under 90 °

Multi-drop hot runner nozzles for side gating under 90 ° without cold slugs, where up to four tips per nozzle are possible.

Multi-drop hot runner nozzles type LHF/LHT: They can be used in conjunction with a heated adapter or a manifold for injection moulding tools with a high number of drops. This series of nozzles is also suitable for processing filled plastics.

The advantages

  • Side gating under 90 °
  • Small cavity distances
  • Optimal temperature profile
  • Installation-friendly plug-in type power and thermocouple plug connections
  • Reduced control technology requirements
