    • 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). The mixture is allowed to react and cure by making sure that the temperature of the mould (6) is higher than said critical temperature. The object (2) with the inlet piece (1) is removed from the mould (6). More particularly, 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 the critical temperature, whereby the extremity of the casting nozzle fits liquid-tight on the filling opening (4) of the above-mentioned inlet piece (1). 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 the cashing nozzle (14).
    • 在模具(6)中形成热固性合成材料的物体(2)的方法,具有至少一个室(9),根据该方法,在临界温度以上反应和固化的组分的混合物放入液体 通过入口件(1)在腔室(9)中形成,该入口件设置有至少一个通向腔室(9)的填充管道(3,5)。 通过确保模具(6)的温度高于所述临界温度,使混合物反应并固化。 具有入口件(1)的物体(2)从模具(6)移除。 更具体地,液体混合物通过插入模具(6)中的壁(8)并通过铸件(6)延伸到模具(6)外部的入口件(1)插入到模具(6)中 喷嘴(14),其保持在低于临界温度的温度,由此铸造喷嘴的末端液密地配合在上述入口件(1)的填充开口(4)上。 至少在模具(6)的填充期间,入口件(1)具有比上述临界温度低的温度,使得固化首先相对于模具(6)的内壁发生,并且最终抵抗 入口件(1),并且在模具(6)中的固化过程中,通过固化喷嘴(14)对固化合成物施加压力。
