Hydraulic Fluid in a Flexible Diaphragm Hydroforming Presses

CNC hydroforming presses of Gefest-H.06 series are designed for hydraulic molding of parts of complex spatial shape from steel, non-ferrous alloys and titanium by pressing with a hydroelastic medium.

The sheet metal takes the form of a solid one-sided matrix under the action of an elastic rubber diaphragm, on the surface of which pressure is exerted by a working fluid (castor oil). High accuracy of matching the shape of the matrix is achieved due to hydrostatic compression of the sheet, in the same at all points of the surface and does not depend on the shape of the surface.
