To reduce the operating cycle and increase the product quality, it is proposed, in the production of mouldings, first of all to introduce the liquid but curable material, in particular plastic, into a mould 1, 2 which, in its interior, is provided with a cavity 5 and, after curing, to carry out demoulding. The central concept consists in generating a sub atmospheric pressure in the cavity 5 before and/or during the charging and generating a pressure gradient in the feed orifice 20. <IMAGE>
