The invention relates to a device for the internal high-pressure forming of components from tubular workpieces, in particular microcomponents, comprising an at least two-part mould, in which a workpiece can be placed, and means for sealing and/or applying pressure to the workpiece at the ends of the workpiece, in which device at least one guide (11) is arranged on the mould (2a, 2b), on which guide a carriage (12) is displaceable, which carriage carries means (4, 5) for sealing and/or filling/applying pressure to a workpiece end (1a), wherein a carriage (12) is displaceable by means of a drive (13, 15) which is arranged separately from the at least one guide (11) and is coupled to the carriage (12) at least essentially such that it is free from transverse forces.
