Mario Di Maio manufactures com-
plete systems and machines for the
metal wire process.
Square section wire rolling in
continuous condition is provided
through wire rolling trains that avoid
unevenness and difficulty faced with
the traditional multi-groove rolling
mill systems, basing on a more
sophisticated mechanical structure
and an accurate electronic control of
the working speeds.
Wire rolling trains can be supplied as
8 or 12-passage models, in three
different series, in accordance to the
dimension of the bar to be rolled, for
a max dimension of 16mm.
For wire drawing, the square wire –
once processed with the rolling mill
– is then reduced to the desired
diameter through the multi-pass wire
drawing machines that can perform
at a very high working speed. The
company’s MDM T12NFS multi-
pass drawing machine combines a
300m/minute speed and the possi-
bility to draw – without breakages –
a 0.12 mm diameter wire, thanks to
its accurate electronic control pulling
system.
