VERFAHREN UND ANLAGE ZUR HERSTELLUNG VON FORMTEILEN AUS VERNETZTEN REAKTIONSKUNSTSTOFFEN

The invention relates to a process for producing moulded components from cross-linked reaction plastics, especially polyurethane, distinguished by the following process stages: the reaction components of the plastics are mixed in the fluid state; the reaction mixture thus produced is applied in the fluid state to a moving conveyor thus forming a continuous layer, and at least partially cured along a moving section of the conveyor to form a semi-finished product; the semi-finished product is formed without cutting by the effect of a pressure of 150 of 400 bar at a temperature of 120 to 350 DEG C until obtaining the moulding. It is possible with this process, using relatively simple moulding tools, to manufacture large-area and thin-walled mouldings which have constant mechanical properties and outstanding surface quality over their entire length.
