<p>Method for forming an object (2) of thermosetting synthetic material in a mould (6), having at least one chamber (9), according to which method a mixture of components, which react and cure above a critical temperature, is put in liquid form in the chamber (9) through an inlet piece (1), which is provided with at least one filling duct (3,5) which opens into the chamber (9); whereby said mixture is allowed to react and cure by making sure that the temperature of the mould (6) is higher than said critical temperature; after which the object (2) with the inlet piece (1) is removed from the mould (6), characterized in that the liquid mixture is inserted in the mould (6) through the inlet piece (1) which sticks through a wall (8) in the mould (6) and which extends outside the mould (6), by means of a casting nozzle (14) which is kept at a temperature which is lower than said critical temperature, whereby the extremity of the casting nozzle fits liquid-tight on the filling opening (4) of the above-mentioned inlet piece (1), and one makes sure that, at least during the filling of the mould (6), the inlet piece (1) has a lower temperature than the above-mentioned critical temperature, such that the curing first takes place against the inner wall of the mould (6) and finally against the inlet piece (1), and during the curing in the mould (6) a pressure is exerted on the curing synthetic via said casting nozzle (14). <IMAGE></p> |
