A moulding device () for moulding a material around a core (), comprising a hollow moulding enclosure () suitable for receiving the core (), and means for controlling the shape of the core () in the hollow enclosure (), the control means comprising means for deforming the core (). The control means further comprise force control means and a control unit () suitable for actuating the deformation means in accordance with information provided by the force control means.

Moulding device

A core for the foundry of an aeronautical part such as a turbine blade, the core being intended to be disposed in an inner housing defined by a mold, the core comprising a body intended to form the internal shape of the turbine blade, an impact portion, disposed on at least a portion of the periphery of the body so as to break a fluid jet when filling the inner housing with the fluid, the impact portion comprising a top and at least one deflection wall converging towards the top.

Core for metal casting an aeronautical part

A refractory core () for fabricating a hollow turbine engine airfoil () using the lost-wax casting technique, the core comprising a main body () and at least one shell () connected to the main body () and defining a cavity () between the main body and the shell, the shell () being configured to come into contact with the airfoil () during fabrication.

Refractory core comprising a main body and a shell

A ceramic material mold for use in molding a turbine engine blade from a molten metal, the blade including a root, an inner platform, an airfoil, and an outer platform, and the mold including a cavity having the shape of the blade, and an auxiliary grain duct including a first segment and a second segment that is an extension of the first segment, the first segment opening out at one end into a first portion of the cavity forming the root of the blade, and at another end into a second portion of the cavity forming a lip of the inner platform of the blade, the second segment opening out at one end into the second portion of the cavity, and at another end into a third portion of the cavity forming a lip of the outer platform of the blade.

Mold for fabricating a monocrystalline blade by casting, a fabrication installation and method using the mold

An installation for manufacturing a part by implementation of a Bridgman method includes in particular a mold intended to receive a melted material and a thermal screen movable with respect to the mold intended to be positioned in front of the solidification front during the directional solidification.

Installation for manufacturing a part by implementing a Bridgman method

A feed system for conveying a molten metal that is to make a casting, the system including a feed channel made of ceramic material that is configured to enable the molten metal to flow by gravity inside the feed channel, the feed channel having a first portion extending in a first direction, and at least one second portion extending in a second direction different from the first direction, the second portion being arranged downstream from the first portion and being connected to the first portion by a junction. The system further includes a damping channel having a first end opening out into the junction and a second end that is closed, the damping channel extending the first portion of the feed channel.
