Hydroforming
means
forming
an
object
with the
aid of
fluid
subjected
to high
pressure.
The
process
utilizes
the
fluid's
capacity
to
always
press
perpendicular
to the
material.
Hydroforming
can be
used to
form
both
tubes
and flat
panels.
In both
cases a
forming
tool is
used
which
comprises
an upper
and
lower
forming
section.
These
forming
sections
are held
together
by a
hydroforming
machine.
The
part is
formed
by the
pressure
of the
fluid
against
the
inner
sides of
the
forming
tool.
When
running
tube
hydroforming,
axial
cylinders
are
added
for
sealing
and
inserting
material.
This
method
provides
following
unique
benefits
compared
to
conventional
technology.
The press
hardening
process
makes it
possible to
produce
sheet metal
parts up to
three times
stronger
than
standard
steel - and
all in the
same press
operation.
Hot blanks
are formed
and cooled
rapidly in
the press
tool. The
process sets
tough
demands for
all
equipment in
the process
to work
together
optimally.
Press
hardening is
an excellent
manufacturing
method for
vehicle
parts that
must be able
to handle
large
deformation
energies. It
is also a
competitive
advantage
for parts
where
advanced
geometries,
high
strength and
low weight
must work
together.
