DEM Costruzioni Speciali is strongly
orientated towards innovation and the
development of special applications for
the ferrous and non-ferrous industry.
The company has a long record of
projects with outstanding demands
in terms of technical performance and
precise order execution, some of which
are detailed below.
In 2010 DEM designed and started up
an automatic compact coiler with extra
capacity up to 5-ton coils.
The challenge consisted in having a
perfect layer oscillated wound coil up to
1,600mm OD and large size with 5-ton
capacity.
Also in 2010, the company supplied
one of the major Eastern European
metallurgical groups of companies with
worldwide operations.
The project included delivery of a
complete state-of-the-art profile wire
rolling line to produce shapes with tight
dimensional tolerances at high speed, yet
with very short, industrial start-up.
In 2009 DEM supplied a leading European
company in the stainless steel and alloyed
steel profile sector.
The challenge consisted of designing and
supplying a complete state-of-the-art
profile wire rolling line to produce shapes
in stainless steel with tight tolerances, at a
high speed of 8m/sec.
A year earlier, DEM supplied a European
company in the stainless steel and
alloyed steel wire sector. Conversion of
a drawing line from die to micro-rolling
concept resulted in higher speed, less
maintenance and cut of intermediate
treatments, and therefore increased
uptime.
The challenge consisted in processing
wires in stainless steel materials and
special alloys using rolling technology,
and making rolls fit to withstand the
heavy load generated by such ‘hard
materials’.
DEM pools resources and know-how with
its parent companies, EVG, Austria and
GCR, Italy, and with customers through
long-term cooperation.
The company is a comprehensive
provider of rolling technology for cold
forming of metals, including the design
and supply of complete profile wire
rolling lines for all metals; flat wire rolling
lines for all metals; cold rolling lines for
processing steel wire rod into reinforcing
wire for the construction industry and
cassettes; microcassettes and core
equipment for wire fabrication; and
equipment for welding wire fabrication.
