With
gas
prices
spiking
and
the
eco-movement
hitting
the
pavement
faster
than
you
can
say,
“hybrid
SUV,”
it’s
no
wonder
auto
manufacturers
are
looking
for
new
ways
to
lighten
the
weight
of
their
vehicles.
It’s
also
little
wonder
that
researchers
around
the
world,
including
José
Imbert,
a
Waterloo
mechanical
and
mechatronics
engineering
lecturer
and
doctoral
candidate,
are
dreaming
up
new
ways
to
make
it
happen.
For
six
years
José
has
been
studying
something
called
electromagnetic
forming
to
force-form
sheet
metal
at
incredibly
high
speeds.
Using
electromagnetic
force,
magnetic
fields
are
generated
that
repel
each
other
to
twist
and
sculpt
sheet
metal
into
desired
shapes.
How
fast
does
it
happen?
Think
100
metres
per
second.
“It
just
happens
so
quickly
you
can’t
see
any
of
the
forming.
You
hit
the
button
and
it’s
instantaneous,”
he
says.
Traditionally,
pieces
of
metal
are
formed
by
stamping,
driving
two
pieces
of
metal
together
to
create
the
third
between
them.
The
technique
works
well
for
heavier,
more
robust
metals
such
as
low-carbon
steel
used
in
most
cars,
but
aluminum
tends
to
tear
or
deform
during
spring
back,
says
José.
He
hopes
eventually
the
gentler
touch
of
electromagnetic
forming
will
help
fix
that
problem
and
lighter
aluminum
will
be
used
in
vehicles
in
order
to
reduce
fuel
consumption.
And
now
that
the
University
of
Waterloo
has
purchased
its
own
equipment
Imbert
is
able
to
work
faster
and
more
efficiently
himself.
“Now
we
don’t
have
to
go
down
to
Detroit.
We
have
everything
we
need
here,
which
is
very
convenient,”
he
says.
