Spray head with separate nozzles for water and release agent

Release agent is applied only to those parts of the mould which come into contact with the molten aliuniniiun. This can reduce the consumption of release agent by another 30 %. 

The use of computer-assisted actuation of the nozzles for the release agent has made the previously used existing array of nozzles for compressed air redundant. This function is now taken over by the nozzles for the release agent. 

An advantage with small series and frequent mould changes is that the spra dng programme can be saved on Ihe computer and can thus be reproduced quickly after a mould change. 

Water consumption can be reduced by about 15 %. There are no losses of water or release agent to be disposed of. No gaseous emissions due to evaporation of release agent are generated. 

No cross-media effects apply. No increase in energy costs is expected.
