Mario Di Maio manufactures complete
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 could 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 MDMT12NFS multi-
pass drawing machine combines a 300m/
minute speed and the possibility to draw
– without breakages – a 0.12mm diameter
wire, thanks to its accurate electronic
control pulling system.
Reduction of a round wire to a flat
rectangular strip – as requested for
different uses in the industry – needs a
high precision flattening rolling mill.
The MDM LSF105X70 model – provided
with coils – is an interesting machine of
compact dimensions. Double coils are
electronically adjustable, with automatic
pulling control – speed and winding
pitch. It provides a high max rolling mill
of 200m/minute, widia rings on the rolls
and roll cooling system also allow you to
obtain very thin thickness (0.05 mm) with
absolute precision.

New polymer from
DSM
Royal DSM has developed a new
polymer which extends the portfolio
for high performance engineering
thermoplastics.
The polymer, described as PA4T, has been
developed by DSM Engineering Plastics,
the inventor in high performance
polyamides with Stanyl® 46.
The new polymer will answer to
market trends for miniaturisation and
convergence of electronic devices like
mobile phones and computers.
It will assist automakers in continued
weight reduction efforts for better fuel
efficiency and lower costs.
PA4T exhibits an exciting and unique
balance of properties including excellent
dimensional stability, compatibility
with lead free soldering, high stiffness
and mechanical strength at elevated
temperatures, high melting point, and
excellent processability in terms of flow
and processing window.
DSM has filed patents on the new
polymer, developed compounds and
held initial investigative trials with
market leaders for various end uses.
