20 Wire & Cable ASIA – January/February 2017
Industrynews
IN today’s world, the word progress
has become synonymous with
expectations of better quality. In the
sector of high carbon steel wire, the
evolution of the chemical composition
of these wires, with always higher
carbon contents, has meant a
continuous innovation of both the wire
production equipment and the entire
production process.
This increase in the mechanical
properties of the wire has amplified the
difficulties of high-speed drawing due
to the development of high
temperatures.
Much has been done to optimise the
drawing process, with new die angles
and significant developments in
lubricant quality, but existing capstan
cooling systems in the wire drawing
machines have meant that it has not
been possible to exceed certain
limits.
The R&D department of Eurolls,
recognised in the design and
production of rolls and cold rolling
cassettes, has developed a solution
that permits exceeding existing limits
by the introduction of a new cold
rolling cassette specifically designed
for high carbon wire production.
The cold rolling process, due to a
lower friction coefficient and an
innovative wire lubrication system,
generates less heat thereby lowering
wire temperature during the reduction
process.
All recent Eurolls wire drawing lines
have been supplied with the possibility
to adopt this new cold rolling system.
Furthermore, these same new lines
have not only an improved capstan
cooling system but also benefit from
the development of a new internal
coating specifically studied by Eurolls
R&D.
This internal coating ensures a
reduced formation of deposits and rust
while guaranteeing an increase in heat
transmission (same cooling capacity
but with a lower quantity of cooling
water).

Indonesian film producer PT Kencar
Sukses Investama is expanding its
presence in the Southeast Asian film
market by adding two more
Davis-Standard cast film machines to
its facility in Sidoarjo, Indonesia.
This brings its total to four
Davis-Standard machines in just over
five years. It has introduced several
innovative food-packaging films to the
region, accounting for a rapid growth
rate and strong customer base.
Kencar was the first company in
Southeast Asia to introduce five-layer
CPP films, and with the additional
Davis-Standard machines will become
the first with six-layer capabilities. This
will enable it to support markets for
high barrier CPP as well as CPE films
that offer better thickness uniformity
and clarity than comparable blown
films.
Kencar president Eddy Soelayman
said: “The Southeast Asia flexible
packaging market is growing at more
than eight per cent per year and
Kencar has outpaced that growth by
more than 50 per cent. We see a
transition in the CPP market from
commodity to high-performance films
that have superior barrier, metal
adhesion, gloss and heat seal
properties.
“We are currently producing five-layer
CPP films with heat seal properties like
CPE with excellent gloss and metal
adhesion. With the new machines we
can take that a step further by
producing CPP films with unique
barrier properties that allow converters
to down gauge and reduce conversion
steps to save cost.”
The Davis-Standard cast film machines
will be higher speed versions of the
original two. Both machines will feature
next generation DSB® barrier screws to
handle Kencar’s diverse range of
materials and film applications.
Feedblock and die technology will
accommodate up to seven distinct
layers in a structure.
The “ironing” roll will be included on
the winder for consistent roll
conformity. Kencar appreciates
Davis-Standard’s proven technology,
which produces films with higher
surface treatment retention, better
metal adhesion and improved oxygen
and water vapour barrier properties, all
critical in flexible packaging.
“Davis-Standard has been excellent in
providing creative solutions for the
unique films we continue to introduce
to the market,” added Mr Soelayman.
“They have a good understanding of
polymer processing and know-how to
transform our vision into final
products.”
