Abstract
The present invention relates to a process for the manufacture of castings from an essentially liquid reactive medium as casting material which, above its gelation temperature, reacts to form a solid material. The liquid reactive medium is fed from a supply tank, in which the temperature of the casting material lies substantially below its gelation temperature. The liquid reactive medium is fed into a casting mould which has been heated to a temperature that lies above the gelation temperature of the casting material. The casting material is substantially preheated directly before it enters the casting mold to a temperature close to but below the gelation temperature of the casting material.
