Abstract

The invention relates to a method of filling cavities and, in particular, mold cavities, with a reactive solid-forming or foam-forming mixture, wherein at least two reactants are introduced into a spatially limited mixing zone, mixed therein as they pass through, and the mixture produced is introduced into a mold cavity where it reacts and wherein the mold cavity is initially enlarged in-part for storing a portion of the mixture, which portion is subsequently transferred to the final mold cavity volume. The object of the invention is to produce plastic articles which are shaped in molds, but also to fill out other cavities, for example, for the purposes of reinforcement.
