In the production of moulded articles wherein reactants are combined, react, and form the material, e.g. foam, composing the article, filling the mould, a mixing chamber for the reactants is combined with the mould. The reactants are introduced and mix in the mixing chamber and issue therefrom into the mould where they react for the formation of the article. In the reaction the mixing chamber can become integrated with the article. The mould can be a shell which becomes integrated with the material produced by the reaction, forming an outer skin of the article.
