Open multi-drop hot runner nozzles
Hot runner nozzles for lateral injection: Precise injection moulding – compact design
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.
Multi-drop hot runner nozzles for side gating: The efficient solution for side injection
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°: Maximum process reliability with minimum control effort
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
