Zusammenfassung:	A method for producing foamed mouldings comprises the steps of providing a mould (1) and introducing a foam-forming reaction mixture (6) into the mould (1), wherein the foam-forming reaction mixture (1) is introduced into the mould (1) under constant injection pressure and in a quantity which is variable over time. The introduced quantity of the foam-forming reaction mixture is changed over time by varying the output of a pump motor acting on the reaction mixture.
