The Energy Efficient Hot Runner
Gunther’s BlueFlow® Hot Runner Technology combines advanced engineering with innovative materials to deliver unmatched performance in injection moulding. Designed for precision, energy efficiency, and flexibility, BlueFlow® nozzles set the standard for quality and productivity.
Blue Flow
Unmatched Temperature Control
In combination with Gunther’s patented bi-metallic titanium shafts, BlueFlow®’s unique thick-film technology ensures:
- Homogeneous temperature distribution along the entire nozzle
- Rapid thermal response
- Prevention of temperature peaks in the melt
By design, thick-film heaters use less energy than traditional coil heaters, making BlueFlow® nozzles one of the most energy-efficient on the market. Tests show up to 58% less energy consumption compared to some competitor nozzles.
Slim, Flexible, and Compact
The slim nozzle and reduced shaft diameter, enhanced by bi-metallic titanium shaft technology, provide:
- Greater flexibility in the temperature profile, improving part quality
- Often shorter cycle times
- Improved gate cooling possibilities
- Reduced mould space requirements for more compact tool designs
Experience the difference with Gunther BlueFlow® – where innovation meets performance.
