Abstract
For the production of polyurethane moldings by the shot process from isocyanate and polyol components, the production is improved in that, in addition to the conditioning already known for the line system, at least one of the commercially available but modified metering pumps is also conditioned in that some of the reaction component made available flows in circulation through the intermediate space between the enclosed metering component and housing of the pump.
