An electronic device includes a housing and a base plate. The housing includes a frame. The frame includes a first end portion having a first inner surface and a second end portion connected to the first end portion to form the closed frame. The second end portion has a second inner surface. The base plate is fixedly connected to the frame. One of the first inner surface and the base plate includes a first protrusion, and the other of the first protrusion and the base plate defines a first latching slot; the first protrusion receives in the first latching slot. One of the second inner surface and the base plate includes a second protrusion, and the other of the second inner surface and the base plate defines a second latching slot, the second protrusion receives in the second latching slot.

A method of manufacturing a component of a turbomachine by powder metal hot isostatic pressing is disclosed, which uses a container defining outside surfaces of the component. A metal insert is located inside the container before filling the container with metal powder, and the insert is left in the component after the end of its manufacturing. In an embodiment, a metal core is located inside the container before filling the container with metal powder, and the core is removed from the component before the end of its manufacturing. In this way, net shape surfaces may be obtained without manufacturing trials.

A stack molding pattern and a shell for manufacturing aircraft turbine engine blades via lost wax casting. The stack molding shell includes a plurality of shell blade elements, each intended for producing a blade, wire elements being arranged within the shell blade elements; and a metal feeder including a plurality of metal outlets, each one radially open towards one of the shell blade elements and connected with the second end portion of the element. The shell includes a protective screen, associated with each second end portion and intended to protect a sensitive portion of the wire elements against the direct impact of a flow of metal from the feeder. The sensitive portion is located in the second end portion, downstream from the protective screen.
