Energy Savings

New methods for producing energy savings when using Hot Runner Systems

 

The benefits offered by hot runner systems for the injection molding industry such as material saenergyvings and cycle time reduction are widely known. However, in the past very little attention was paid to the amount of energy required to operate the hot runner equipment. Energy savings have become increasingly more important as electricity costs have increased in recent years.

Hot runner systems are comprised of hot runner nozzles and a manifold for multi cavity applications. The melt conveying channels inside these components are typically heated with 230V heaters.  The energy requirement for these heaters depends on the type of resin, nozzle/manifold mass and other factors.

Through the use of new materials and manufacturing methods the energy consumption of hot runner nozzles can be reduced on average by 35%. The energy savings for the nozzles can be significant when higher cavitation molds are produced due to the high number of nozzles installed.
