Abstract: A casting device with which, by introducing a thermocurable plastics into a heatable casting mould (1), the plastics is thermally cum in that casting mould at least to such a degree that a casting moulded in that manner can be released from the mould, comprises a reservoir for the thermocurable plastics and a feed means for feeding plastics from the reservoir into the casting mould (1), which mould has an inlet opening that extends at least along a substantial portion of the length of the casting to be moulded, wherein the casting device comprises a separate adapter (2) in which the feed means (20, 221, 23) for the plastics is arranged and which can be connected to the casting mould (1) in such a manner that, when the adapter (2) has been connected, an outlet opening (23) provided in the adapter (2) is arranged sealed to and substantially congruent with the inlet opening of the casting mould (1).

Abstract: The present invention relates to an oven for heating an essentially liquid medium, especially a reactive casting material, flowing through the oven. The oven has an inlet into a channel for the medium to be heated, in which channel there is arranged a separate pipe through which the medium to be heated flows and in which it is heated by electromagnetic radiation. Several heating units are arranged along the channel, each of which comprises an electromagnetic radiator containing a waveguide. The waveguides guide the radiation to the channel through which the medium flows and which couples the radiation into that channel. The heating units are substantially decoupled from one another by means of a decoupling diaphragm that is provided in the channel and is arranged between two adjacent heating units or radiators essentially at right angles to the direction of flow. The pipe through which the medium flows passes through a passage in the decoupling diaphragm, thus also constituting a support for the pipe.

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.
