Abstract

For measuring the air charge of a plastic component for a low-pressure multicomponent foam system, the gas-charged plastic component is admitted into a measuring chamber. The gas pressure of the plastic component displaces a measuring piston in the measuring chamber and the displacement distance of the piston is a measure of the gas charge.
