Device for the manufacture of a composite part

摘要

The present invention relates to a process and a device for the production of a composite part by the sequential introduction of several fillings (consisting of at least one free-flowing reaction mixture, of which at least one forms a foamed material) into the hollow space of the mold of a closed form tool. A mixing device is attached to form tool. The mixer comprises injector nozzles for the reaction components pointing into a mixing chamber and an ejector piston for the cleaning of the mixer chamber. The ejector piston may be slid forward right up to the outlet orifice of the mixing chamber.
