Techint Technologies
strengthens position
Techint Technologies has joined forces
with Hypertherm, a key-player in India
for the design and supply of industrial
furnaces for the metal industry.
Located in Mumbai, Hypertherm was set
up in late 2001 by six technocrats with a
combined furnace industry experience of
more than 150 years.
The company, with a reference list of more
than 50 installations in India and abroad, is
specialised in the thermal engineering field
with renowned competences in Reheating
Furnaces, Furnaces for Processing Lines,
Continuous and Batch Heat Treatment
Furnaces, Aluminium Furnaces, Lime and
Dolomite Kilns and Kilns for Ceramics.
The joint venture, named Techint
Hypertherm Pvt Ltd, will continue its
operations from Mumbai where they
employ almost 70 people and mainly
serve the Indian market.

Zwick comes out
on top in universal
hardness testing
With its latest ZHU-topLine hardness
tester, Zwick is strengthening its market
lead as a supplier of premium universal
hardness testing equipment.
The first fully functioning prototypes
were showcased at last year’s
International Forum for Materials Testing
in October in Ulm, Germany. These
machines have test loads from 1 to
250kg (9.81 to 2452N) and went on sale
at the start of the year.
During the development process,
special emphasis was placed on
high operating and measurement
convenience.
As a technology leader this universal
hardness tester is designed for
hardness tests according to Vickers,
Brinell, Rockwell, and other procedures.
It has been developed especially for
test laboratories/materials research,
or quality assurance in industrial
production.
Unique features of the machine
include its advanced digital zoom
optics for carrying out a wide range of
applications using a single lens, and
‘closed loop’ technology for automatic
load application.
An optional image processing system is
available for fully automatic evaluation
of the indentations, as are other options
and modules, like a motorised turret
and motorised compound table.
The hardness tester connects directly to
Zwick’s proprietary testXpert® software
resulting in a very easy to use and
reliable testing system. In addition, the
online language switching is extremely
useful for international organisations
and applications.
Zwick will be introducing more
hardness testers from this series up to
750 and 3000kg (7357N and 29,430N)
during 2007.

The ZHU250top – the first machine
from a new advanced product line for
hardness testing
▲
Cable specialist Nexans will present
optimised corrugator technologies for
its UNIWEMA® machines at TEKNO/Tube
Arabia 2007, which takes place in Dubai
from 13-16th January 2007.
UNIWEMA machines are used to
manufacture smooth or corrugated tubes
and cable sheaths by continuous forming
and welding of metal strips.
The machines process stainless steel, steel,
copper or aluminium and their alloys,
welding the material in the TIG (tungsten
inert gas) process or using lasers.
Depending on the machine model and
equipment, tubes with an outer diameter
of 2mm-350mm can be produced. Typical
wall thicknesses for steel are between
0.1mm and 3mm.
Corrugation gives tubes or cable sheaths
flexibility. A rotating disc-type tool presses
helical or annular corrugations into the
tube, with the shape of the corrugations
varying depending on the tool, feed rate,
pressure and corrugator speed.
The company’s new optimised tools
feature structural improvements to the
corrugator head bearing, allowing the
creation of deeper corrugations.
Production speeds of up to 35m/min (with
UNIWEMA 25) and corrugator speeds up
to 6,000rpm can be achieved. The new
tools can also be used to retrofit older
UNIWEMA systems.
With the corrugation depth, the surface
per cable length increases, which improves
heat dissipation and increases flexibility.
The improved bending properties of
corrugated flexible metal tubes (CFMT),
in particular, open up new fields of
application, such as the production of
easy-to-install water and gas lines for
mains connection.
And it is that technology that can
also provide benefits in vehicle air
conditioning systems, where shock and
pressure-resistant flexible corrugated
stainless steel tubes take on the
task of transporting carbon dioxide,
which is soon to replace conventional
refrigerants.
