A process for melting metal parts and casting the melt in at least one mould and a corresponding combined melting and casting furnace plant are described. In the process, metal parts to be melted are brought into a crucible furnace, and a molten metal is produced therein and made ready for casting. A riser tube integrated in a lid of the crucible furnace is heated in a position remote from the crucible furnace, and the lid with heated riser tube is brought into a position closing the crucible furnace, in which the riser tube projects into the molten metal. A mould is arranged on the lid in a casting position above the riser tube, and the molten metal is introduced into the mould from below by pressurising the melt in the crucible furnace. The combined melting and casting furnace plant is designed to carry out such a process.

A method for joining an aluminum material includes, in the following order, arranging a first wrought aluminum alloy material along a first jig in an internal space defined between the first jig and a second jig that is arranged to face the first jig and has a pouring port, pouring molten aluminum toward the first wrought aluminum alloy material through the pouring port under pressure to cause the molten aluminum to collide with a surface of the first wrought aluminum alloy material, thereby digging down the first wrought aluminum alloy material at a collision position between the molten aluminum and the first wrought aluminum alloy material, and flowing the molten aluminum together with a fraction of the first wrought aluminum alloy material removed by digging within the internal space along a surface of the first wrought aluminum alloy material around the collision position.

To provide a machine and method for efficiently pouring and definitely filling only a desired cavity with molten metal to cause the molten metal to solidify there. The automatic pouring machine (1) that has an ability to pressurize having a ladle (2) for pouring molten metal into a mold (A) comprises a pouring unit (10) that can move a ladle in the direction parallel to, and in the direction perpendicular to, a line (L) of molds where a plurality of molds are transported and a unit (20) for pressurizing the molten metal that is supported by the pouring unit and that supplies pressurized gas and a granular material to the mold into which molten metal has been poured. The unit (20) supplies the pressurized gas and the granular material to the mold that is next to the mold into which the pouring unit pours molten metal.

A method to manufacture reticulated metal foam via a dual investment solid mold, includes pre-investment of a precursor with a diluted pre-investment ceramic plaster then investing the encapsulated precursor with a ceramic plaster.
