Filler-containing molded parts or articles are produced from a free-flowing reaction mixture, e.g. of polyol and isocyanate, in a manner which permits the changeover to a different filler content to be carried out more rapidly and, possibly, without material loss. This is achieved by dividing at least one of the reaction components into at least two portions, at least one of which is charged with filler, by adjusting the mixing ratio of these portions and hence the filler content of the finished molded part. At least two storage vessels are provided for at least one of the reaction components. Adjustable metering devices are arranged between these two storage vessels and the mixing device.
