Abstract: A moulding apparatus for forming an object (20) with a mouldable material, the moulding apparatus having a forming region (4) delimited by a lateral surface (5) extending around a central zone (6). The moulding apparatus comprises: a plurality of sectors (8; 80; 108; 208) defining the lateral surface (5), each sector (8; 80; 108; 208) having a body (9) delimited by a forming surface (11; 311), at least a first pushing device for applying, on a first sector (8a) of said plurality, a first force (F1) directed towards the central zone (6) in a first direction (D1), at least a second pushing device for applying, on a second sector (8b) of said plurality, a second force (F2) directed towards the central zone (6) in a second direction (D2), the second direction being arranged transversely to the first direction (D1). The second sector (8b) is in contact with the first sector (8a) for transmitting the second force (F2) to the first sector (8a), so that the forming surface (11 ) of the first sector (8a) is moved towards the central zone (6) under the combined action of the first force (F1 ) and the second force (F2), in order to reduce the volume of the forming region (4).

Abstract: A method for forming an object, comprising the steps of: - providing a mould (1; 101; 201; 301; 401; 501) comprising a first mould part (2; 102; 202; 302; 502) and a second mould part (3; 103; 203; 303; 503) opposite to each other, a part selected from between the first mould part and the second mould part comprising a plurality of sectors (8; 108; 208; 308; 508) for shaping at least a lateral portion of the object, the sectors delimiting a variable-volume forming region (4) of the mould; - positioning a dosed amount (100; 400; 500) of mouldable material between the first mould part and the second mould part while the mould is in an open position; - displacing the first mould part and the second mould part towards each other in a moulding direction (D), to define between the first mould part and the second mould part a closed forming chamber (17) bringing into contact respective abutment surfaces (71, 72; 571, 572) of the first mould part and the second mould part, the abutment surfaces extending transversely to the moulding direction, The method further comprises the step of moving the sectors transversely to the moulding direction to reduce the volume of the variable-volume forming region. The mould comprises a forming component (15; 115; 215; 315; 515) which penetrates into the variable-volume forming region, compressing the mouldable material in the moulding direction.

Abstract: A method of and apparatus for sinter forging a precursor powder to form a film may reduce or eliminate the stress in the film and may facilitate processing of continuous length of films such as ceramic films for use in batteries. The precursor powder can be provided on a substrate and is simultaneously heated and pressed in a pressing direction parallel to a thickness of the film so as to sinter and densify the precursor powder to form the film in a sinter forging area. Notably, in a plane perpendicular to the pressing direction, there are no lateral constraints on the sinter forging area or the material received therein.
