Eco+ and EcoSpray
Spray solutions with saving potential
Estimated savings with microspraying (Eco+) with Wollin EcoSpray
- Cycle time 10 - 20%
- Energy (mold tempering) 60 - 80%
- Compressed air (vol.) 70 - 80%
- Fresh water 99 - 100%
- Waste water 100%
- Mould life 50 - 300%
Reduction of scrap rate, easier rework, lower maintenance effort, significant increase in die service life up to 300%
In the die casting industry, the development of resource-saving technologies is a continuous endeavor. Wollin is taking the lead with the development of the patented Eco+ microspray technology.
Eco+ and EcoSpray essentially work with two developments:
- Application technology that optimizes the lowest spray quantities possible
- Improved release agents (oil/water-based) which operate at higher temperatures, up to 400°C
The use of oil- or water-based concentrates, combined with Eco+ micro-spray technology, offers:
- Economic advantages
- Ecological advantages
- Production advantages
- For Eco spray, the following equipment needed is:
- Spraying tool with FSD
- Release agent supply such as OSA 1-50-2 or OSA 2-15 - Expected outcomes using Eco spray:
- Resource-saving (when using an appropriate release agent)
- Better part quality
- Longer die service life
- Continuous spraying
- For Eco+ spray, the following equipment needed is:
- Spraying tool with DD or DDV nozzles
- Release agent supply such as OSA 1-50-2 or OSA 2-15
- ECO-prepared mold spraying machine (ex works or retrofi tted)
- Pressure boosting station if air pressure network < 7 bar (only for DDV nozzles) - Expected outcomes using Eco spray:
- Resource-saving (when using an appropriate release agent)
- Better part quality
- Longer die service life
- Lower release agent consumption
- Higher process reliability
- Volumetric spraying
