Abstract

The present invention relates to a method and a device for producing shaped articles from a multi-component reaction mixture which forms, for example, polyurethane, epoxy resin, polyester resin or polyamide, by mixing at least two of the individual components in at least two premixing chambers to form multi-component reaction mixture and these mixtures are subsequently mixed in a single-stage mixing chamber to form a mixture which is introduced into a shaping zone in which it is cured to form the shaped article.
