ABSTRACT A method is disclosed for the production of mould parts by an automatic mould part producing apparatus which comprises a mould chamber having pressure plates moveable towards one another and mould plates fastened to the pressure plates and a container for holding a supply of mould material. The container is disposed above the mould chamber and communicates therewith via a funnel-shaped inlet wherein a pressurized gas is introduced into the container above the supply of material for inserting the material via the funnel-shaped inlet into the mould chamber. Further pressurized gas is used to fluidise the material in the throat region of the funnel-shaped inlet and the method is characterized by the further steps of continuously adjusting the pressure of the pressurized gas above the supply of material in dependence on the form of the mould part being produced and of continuously and independently adjusting the pressure of the gas used to fluidise the material in the throat region of the funnel-shaped inlet in dependence on the form of the mould part being produced.
