BlueFlow® Technology from GÜNTHER Hot-runner technology

Günther‘s innovative BlueFlow®hot runner nozzle results in molded parts of outstanding quality.
The BlueFlow® hot runner nozzle sets new standards for quality and design of parts made of thermally sensitive plastics. This results in better or even completely new application possibilities, depending on the application area in different sectors of industry.

Manufacturing at the right temperature
The thick film heater makes it possible to adjust the heating capacity to the exact power requirement in each single section over the entire nozzle length in order to reach a homogenous temperature. The plastic material in the material tube is hardly exposed to thermal stress, which means that the physical properties of the end product are obtainable even with thermally sensitive plastics and very small parts. Parts weighing less than 0.02 g have been successfully manufactured by indirect gating

From zero to sixty
The BlueFlow® hot runner nozzle’s impressively rapid thermal response is due to its compact design. Its small dimensions require a quick controller capable of regulating the temperature within a very narrow range, e.g. our DPT type controller. The nozzles can be operated without a "soft start" because their construction makes them non-hygroscopic.

Multi-Tip Nozzle OktaFlow® from GÜNTHER

Guaranteed to be free of problematic, production-related “cold slugs”, these particularly cost-effective and space-saving multi-tip nozzles in the OktaFlow® series in either radial or linear design allow direct side gating. Both designs share the same features: They can be used in conjunction with a heated adapter or in combination with a manifold for multi-cavity injection moulding. Optionally, wear-resistant nozzle tips can be used when filled materials are processed to ensure long term use in continuous operation. The tips can be replaced individually. Quick colour changes on the machine reduce downtimes.

• Side gating less than 90° without "cold slugs".
• Close cavity spacing in multi-cavity, compact moulds.
• High number of cavities in a compact size.
• No need to divide inserts
• Mini-manifold supported on floating bearings, therefore unaffected by heat expansion.
• Optimum temperature profile, since the control zone for the tips is separate.
• Quick and easy replacement of nozzle tips without having to remove the entire nozzle.
• Easy-to-install, plug-in power and thermocouple connections.
• Less control technology required.

Valve-Gate Systems from GÜNTHER

Are your demands high in terms of appearance, reduced cycle times, minimal shear stress, wide gate diameters and high process reliability? Then no need to look any further. The answer is: Valve gate technology

The GÜNTHER valve gate portfolio includes numerous valve gate nozzles and needle actuation options. This allows the application-specific adaptation to the mould concept – both technically and economically perfect. The smallest and largest shot weights and gate cross-sections ranging from 0.8 to 5.0 mm can be achieved with valve gate technology.

The innovative design of the contouring needle guide and the optimised valve gate needle allow non-contact and wear-resistant operation. When closing, the needle is centered by means of a conical guide, until it fully and precisely enters the cylindrical guide.

The needle guide is mounted on floating bearings in the material tube. If worn out, the needle guide can be easily replaced.

Special holes in the mould clamping plate allow the position of the valve needles to be adjusted individually from the outside.

Up to 50 % GF-filled plastics can be processed, depending on the application.

About us

Company details


Since 1983 GÜNTHER Heisskanaltechnik has passionately dedicated itself to producing hot runner systems and nozzles for the plastics industry. We have not only directly experienced all stages of development in hot runner technology, but we have actively participated in this process. For a company that wants to compete in the market in the long run it is crucial to be always one step ahead. Innovation is the key word. Innovation does not mean using trends, but setting trends.

This is the path we have always followed. Today we are among the leading manufacturers of hot runner systems, from precise standard and complete systems to customized products. With our team of almost 200 excellently trained staff members we set new standards, from technical advice to design and engineering to production and commissioning of complex hot runner systems.
