Additional components – nucleation using air or CO2
CO2 nucleation in daily tank
CO2 nucleation in buffer tank
Outstanding product quality
Gas nucleation is carried out either directly in the daily tank of the metering machine or in a separate tank connected upstream of the daily tank. Precision metering, high throughput and quick post-nucleation ensure an optimum production process.
The air is metered into the machine's storage container. This ensures a uniform gas charge from shot to shot and from the beginning of a shot to the end. A dynamic mixer ensures perfect homogenization of the gas and the component. The nucleation unit is installed in the daily tank bypass circuit and has its own control system.
KraussMaffei offers two different processes for CO2 nucleation: CO2 nucleation in the buffer tank (batch) or directly in the daily tank. CO2 concentrations can be configured from shot to shot.
