Gunther Hot Runner Solutions
For more than 40 years Günther have been a global market leader in high-quality, high-precision Hot Runner Systems, engineered for moulds with anywhere from a single cavity to 128+ impressions. Designed to process everything from commodity plastics to the most demanding technical polymers, Günther systems deliver superior performance through:
- Patented bi-metallic titanium shafts for exceptional heat control and perfect sealing
- Hydraulic, pneumatic, and electric synchro plate or piston driven valve gate systems
- Patented replaceable gates for valve gate nozzles – our famed PM insert technology
- Advanced multi-tip nozzle designs and a complete range of hot runner controllers
- Micro moulding possibilities with part sizes as small as 0.004g
At the heart of every Günther Hot Runner nozzle is the innovative, patented bi-metallic titanium shaft—a technology that minimises heat transfer from the nozzle to the mould tool and ensures an extremely homogenous temperature profile while delivering unmatched precision sealing. This advantage, combined with our proven BLUEFLOW® thick-film heater technology, ensures energy efficiency and outstanding moulding performance.
We were the first in the industry to introduce a plate-operated valve gate system and we remain at the forefront of this sector today.
Whether you need open or valve gate systems for single or multi-cavity production, Günther offers complete hot halves or system-only solutions—backed by expert UK-based advice, installation, and mould trial support.
