Hydroforming machine Formbalancer FB25

The FormBalancer is a hydroforming machine that shapes metal sheets into a tool form by applying very high pressures. Pressures up to 4000 bars acting on the formed part have to be produced by high tool closing forces without generating leaks or bending the tool. This task is accomplished by a patented closing system, the design of which differs substantially from conventional press technology. The advantage lies in a compact design, leading to considerably reduced investment requirements. This design enables system installation at ground level; hence the installation costs are reduced substantially and a high flexibility is ensured.

The FB hydroforming machine is manufactured completely at our premises. Customers all over the world put their trust in our know-how and engineering quality »made in Germany«. The FormBalancer can be adapted to customers specifications and supplied as a turnkey system at the site of the customer.

Film showing the sequence of operation

The production method of the FormBalancer is as innovative as it is versatile, regarding the materials that can be used, their shapes as well as the tools. This forming technique allows also the utilisation of pre-treated materials, which have so far been critical factors in the production of complex geometries.
The tools are designed so that also components with counteracting geometries can be manufactured in one operation. The tool structure consists principally of a pressure plate with or without seal, through which the pressurized fluid for the deformation is pressed, and the matrix (i.e. the negative moulding tool).

The principle of hydroforming allows an excellent degree of deformation. Due to the three-dimensional load applied to the material, components with small to medium drawing depths will show little internal stress and little tendency to return to its original shape when the load is removed.
