A moulding apparatus and method

A method for forming an object with a mouldable material in a forming region delimited by a lateral surface extending around a central zone, wherein the lateral surface is defined by a plurality of sectors, each sector having a body delimited by a forming surface, the method comprising the steps of:

• applying, on a first sector of said plurality, a first force directed towards the central zone in a first direction,
• applying, on a second sector of said plurality, a second force, directed towards the central zone in a second direction, the second direction being arranged transversely to the first direction,
• compressing the mouldable material in a moulding direction transversely to the first direction and the second direction, using a punch which progressively penetrates into the forming region;
• wherein the second sector is in contact with the first sector and transmits the second force to the first sector, so that the forming surface of the first sector is moved towards the central zone under the combined action of the first force and the second force, thereby reducing volume of the forming region after the mouldable material has been introduced into the forming region.
