Reduce Material Costs in
Automotive Wire Production
Imagine: You are producing an ultra-thin cable
with 0.13 mm² at a production speed of 1800
m/min. Now you get the task to monitor the
insulation color just by looking at it. Do you think
you could detect color variations in - let’s say - 200
m of cable on the running line? An impossible
task. This is where Rosendahl sees cost-saving
potentials by using an extremely sensitive
color recognition system, called DVS SK-400-C.
Rosendahl developed this innovative sensor
system to detect even the slightest deviations.
The color recognition sensor
system measures the main
and stripe colors, as well as
the stripe width, according
to previously set references.
It is also possible to optimize
the product recipe. Due its
sensitivity, especially the
master-batch demand can be
decisively reduced.
Rosendahl has subjected it to
intensive tests on their RA-A
automotive wire production
line. The results reveal that
recipes with 2.5% master-batch
can easily be decreased down
to 1.5%, while still maintaining
the same color shade. All
these improvements lead to
immediate savings regarding
the master-batch, and thus on
material costs.
The DVS SK-400C-C’s main
component is a PC-based
evaluation unit with 360°
camera surveillance. This unit
consists of four cameras which
are covered by a protective
housing. This enables
continuous color quality
monitoring, which is also
displayed on the reel protocol.
Color reliability is therefore
immediately assured, which
makes color complaints and
faulty productions a thing of the
past. That means that waste and
scrap are significantly reduced at
start-up, during production and
even during color changes.
The system can be integrated
into a new or existing
production line. It can also be
used as a stand-alone unit.
