A method and a device for manufacturing a part starting from a cushion made of deformable material, in particular for an edge of an element of an aircraft. The device includes a preparation unit to create a cushion with two plates and, between the plates, an internal space with an opening, and a molding unit comprising a mold in which the cushion is positioned, the mold comprising two shells and an imprint corresponding to the shape of the part to be manufactured, the molding unit configured to inject a pressurized fluid into the internal space of the cushion through the opening to deform the cushion such that it matches the imprint and forms the part, the device being capable of manufacturing one-piece parts of various sizes, and in particular parts having complex shapes, in particular non-developable shapes.

A cover plate of a box body for a server includes a main body, a folding edge, and a buckle. The folding edge is vertically connected to the main body, the buckle is disposed on the folding edge, and the buckle can extend along one side of the folding edge and face the main body. The present disclosure also provides a box body and a box body manufacturing method.

Systems and methods for forming 3D plastic parts that are cost effective in low volume, have excellent fit and finish, and use many components from 2D construction are disclosed. The systems and methods involve selecting a design and modelling the design. The design comprises 2D and 3D components of plastic parts. A 3D forming buck corresponding to the 3D component is manufactured. At least one of a 2D part and the 3D forming buck may be heated. The 2D part may be loaded onto the 3D forming buck for a predefined period of time. The 3D part formed after the loading may be separated from the 3D forming buck. The 3D part is the 2D part generally having taken the shape of the 3D forming buck. The 3D part may be cooled to obtain an end product.

A method of manufacturing a hollow aerofoil component 100 for a gas turbine engine 10 comprises joining a first panel 200 to a second panel 300 using bonding, and hot forming the panels into shape. The bonding step and the hot forming step are performed in the same rig, thereby optimizing process time and component quality.

A method for manufacturing a metal container includes a first step of forming a substantially planar four-sided bag using a metal plate; a second step of sandwiching, by first and second parallel plate jigs, one surface and the other surface of the four-sided bag formed in the first step; and a third step of pressurizing an inside of the four-sided bag while maintaining a contact state by the first and second parallel plate jigs with respect to the four-sided bag sandwiched between the first and second parallel plate jigs in the second step, and expanding a volume space in the four-sided bag while increasing a distance between the first and second parallel plate jigs.

A hot blow forming method for the aluminum alloy sheet carries out a hot blow forming to an aluminum alloy sheet using a first metal mold being a female mold for forming having a protruding surface portion on an inside surface thereof and a second metal mold for gas introduction. Immediately prior to the hot blow forming, a temperature (T1) of the aluminum alloy sheet and a temperature (T2) of the first metal mold satisfy a relation (T1)−(T2)≧30° C. and the temperature (T2) is equal to or higher than 400° C. In the hot blow forming, the aluminum alloy sheet is made to be brought into contact with at least a part of the protruding surface portion of the first metal mold within 30 seconds from a start of the gas introduction from the second metal mold.
