Special advantages of hydro-pulseforming with the Hy-P-Form process
step-by-step forming of the component in a single die.
Unlike electromagnetic high-speed forming, the hydro-pulseforming process permits a step-by-step forming of the component in a single die.
It is no longer needed to apply the required forming energy in one process step. This reduces machine production costs as well as wear of machine components and tools. Moreover, the required quality of the component can in many cases only be achieved by a sequence of several process steps taking place in only one die.
place free punches
Representing the only technology to replace one half of the die by a transfer medium, e.g. water, the hydro-pulseforming process permits to place free punches into the metal plate before it is formed.
As a consequence, the finished part shows considerably more homogenous sheet thickness due to “deep-drawing effects”. This is why the component can generally be produced using thinner original material while keeping the required minimum thickness.
At the same time, less energy is needed for the forming process because of the reduction of the stretch-forming areas.
As this example of a twin sieve inlet produced with the CERABITE® process shows, the hydro-pulseforming process permits to place even so many free punches before starting the forming process that in principle a perforated plate can be used as material to be formed. It is possible to form any laser-cut or punched metal sheet.
