Abstract (en)
[origin: WO9213662A1] The present invention relates to a method for moulding a metal alloy ingot, characterized in that it comprises the pressure casting of the alloy inside a mould (33) maintained during the whole casting process to a temperature higher than the room temperature and lower than the solidus temperature of the alloy. The present invention also relates to a pressure moulding method of a metal alloy by using said ingot, characterized in that it comprises heating (20) the ingot to bring it to a temperature comprised between the solidus and liquidus temperatures of the alloy and injecting it under pressure in a mould (33a, b). The present invention also relates to a moulding machine allowing to implement such methods.
