Innovative BlueFlow® hot runner nozzle significantly reduces energy consumption.

The BlueFlow® hot runner nozzle is a real energy-saving wonder: As compared to conventional GÜNTHER hot runner nozzles, the BlueFlow® hot runner nozzle reaches energy savings of up to 30% during injection molding operations. When compared to various competitors’ products of a similar size, the energy savings potential can be as high as 50%.

50% lower energy consumption of the BlueFlow®-nozzle

Energy-saving technology

The energy efficiency of the BlueFlow® hot runner nozzle is a result of its small installation size as well as its absolutely precise and homogeneous temperature distribution, its quick thermal response, and the innovative technology of thick film heaters. No other technique allows heat generation as close to the material.

Small
yet superb

The compact size of the BlueFlow® hot runner nozzle enables smaller molds and thus smaller injection molding machines, considerably reducing energy consumption. With up to 50% less energy required, production becomes more cost-effective, due to lower energy consumption as well as less cooling load. Reducing the heat applied in the mold also reduces the heat that must be dissipated.

At operating tempe-
rature in no time

Its quick thermal response makes it possible to start manufacturing immediately, avoiding time loss and long heating up procedures. The shorter initiation time therefore considerably contributes to the BlueFlow® hot runner nozzle‘s lower energy consumption.

A superior configuration

The innovative configuration of the BlueFlow® hot runner nozzle leads to a lower average temperature and subsequently to a lower energy consumption. The material tube expands slightly more when heated, which reduces the air gap between it and the heater. This results in a better heat transfer, which, in turn, leads to a lower energy consumption.
