Wire & Cable ASIA – January/February 2007
Success at wire 2006 in Düsseldorf,
Germany, has seen Extrudex receive a
large number of enquiries for extruders
and follow-up equipment for the
production of miniature cables.
And several successful sales of mini
extrusion systems has been in the
medical technology industry.
Due to ever complex systems in
the medical and automation fields,
data and power supplies need to be
securely provided in the smallest space
available.
This means conductor diameters in
the range of AWG 25 – AWG 50 and
wall thicknesses in the micron range,
eg 20µ. The required tolerances
correspond to these and keeping to
them is a must.
The Extrudex extruders with screw
diameters of 12 and 15mm have a
conveying length of 25 D. Minimum melt
stopovers prevent excessive demands
and reduce any quality loss, such as
inclusions or burns. Additionally, this
keeps rejects to a minimum.
Output is between 50 and 3.500 g/h
depending on the material and tools
used. The unit is driven by a compact,
maintenance-free AC motor. The
conveying screw range is designed
for standard pellet shapes and can be
optimised according to the materials.
More than 50% of all enquiries related
to fluoric plastics. Extrudex has long
had procedural competence in this
field due to supplying equipment for
many different applications.
The extruder for this field is corrosion-
protected in all material carrying areas
and equipped with high temperature
heating systems.
Installation of the extruder can be
according to clients’ individual needs.
There are machine stands with
horizontal or vertical adjustability for
localised use.
Alternatively, a permanent base frame
with integrated gear and temperature
controls can also be supplied.

For continuous online quality control
of wires and cables, Sikora delivers
state-of-the-art devices for diameter,
wall thickness, eccentricity and ovality
measurement, detection of lumps and
neck-downs, as well as spark testing
directly on the extrusion line.
Leading Sikora’s future-oriented
product developments is the X-Ray
2000 series for diameter and wall
thickness measurements on insulation
and jacketing lines, and the Centreview 2000 series for non-contact
eccentricity and diameter measurements on LAN, coaxial, RF, telephone
cables, automotive and building wires.
X-Ray 2000’s success comes from Sikora’s experience applied to satisfying
customer demand for a reliable solution for on-line measurements without
any undue time delay during the production process.
