Technologynews
CbS Technologies, India, has developed a 100%
consumable-free and maintenance expense-free portable
wire drawing oil centrifuging machine, specifically for wire
drawing application.
The company claims that the machine offers the following
advantages: increases die life to more than double;
ensures the maximum speed of the wire drawing oil; helps
production of bright finished wire; reduces consumption of
lubricant; helps recovery of 0.5% to 1% of the material
from the lubricant; repeat pump failures are avoided; and
there is no chocking of oil lines.
The machine has a 10kg material holding capacity, and
can be cleaned in two to five minutes.

PTFE films and tapes
DeWAL Industries, USA, supplies
high-performance PTFE films and
tapes to the wire and cable industry.
The company’s skived PTFE is used
for its high temperature resistance,
dielectric strength and low friction.
Virgin or conductive, and as thin as
0.013mm, it is often used in
aerospace, power and high flex
cable applications.
DeWAL’s unsintered PTFE is used
primarily as insulation and outer
jacketing for wire and cable at
temperatures up to 246°C, from
0.038mm to 0.508mm, and with a
density of 1.5g/cc. The company has
developed a complete line of vibrant,
RoHS-compliant colours, and can
add other fillers to meet the
requirements of highly engineered
wire and cable.
The company has also developed
technology to manufacture high
tensile, low density film – as low as
0.4g/cc.
These films are used to wrap primary
wires in high flex cable, and other
products in this family were
developed to meet demanding
coaxial cable applications, where low
signal loss is critical. DeWAL uses a
proprietary process to laminate its
fluoropolymer films with dissimilar
materials – often elastomers or melt
processable fluoropolymers.
All DeWAL slit film and laminated
products can be flat pad packaged
and, depending on dimensions,
some skived, unsintered and low
density PTFE can be traverse
packaged. Pyramid packaging is
also used for some skived film and
narrow films.
