Abstract

The present invention relates to a high-pressure mixing head for mixing at least two reactive plastic components, containing a mixing chamber, into which there lead two injection nozzles arranged opposite one another for the components, a proportioning piston which is displaceable in the mixing chamber and a settling and outflow chamber with a cleaning slide extending substantially perpendicular to the axis of the mixing chamber, characterized in that the settling chamber and the cleaning slide have a substantially rectangular cross-section with an axial ratio from 10 to 100. The axial ratio is defined as the ratio of the width of the settling chamber and the cleaning slide to the thickness of the settling chamber and cleaning slide.
