Production sequence, shown on the example
of a longitudinal member
Once it has been cut to length, the profile is
laid into a tool consisting of an upper part
and a lower part.
As the tool closes the flange is trimmed. At
the same time, the axial cylinders are driven
in and the profile is filled with liquid.
A pressure of approx. 1700 bar is then built
up, and the profile is formed in the tool shape
and calibrated.
When the final pressure is reached the hole
cylinders, which up until this point have
closed off the openings for additional hole
operations, are driven outwards.
As a result, a defined part is pushed out of the
profile together with the hole cylinder, thus
creating the break-out.
The part can then be taken out.
The entire process takes about 25 seconds.
