Polymerisable material is forced out of a supply container (20) through an injection opening (8, 8') into a polymerisation mould (12, 12'). In the polymerisation of the material, a polymerisation rate is maintained which decreases from the end of the polymerisation mould (12, 12') opposite the injection opening (8, 8'), via the injection opening (8, 8'), to the material supply (19). During the shrinkage, occurring during polymerisation, of the polymeric moulding formed, further polymerisable material is forced supplementarily out of the supply (19) into the mould (12, 12'). In order to maintain the gradient of polymerisation rate, the polymerisation mould (12, 12') can be heated by a heat source such that a temperature gradient occurs in it. The process prevents a premature polymerisation of the material in the supply container or at the injection opening, and mouldings with high accuracy of detail can be produced in a short polymerisation time. <IMAGE>
