GEO-Reinigungstechnik specialises in
the production of wet chemical cleaning
systems for wire, strip, tube, cable, rod
and similar longitudinal configurations.
Almost all of the demands on the
cleaning processes can be realised with
proven GEO components, such as high
performance ultrasonic tube reactors
and high pressure or steam jets.
Geo in-line cleaning systems can be
complemented
by
state-of-the-art
systems for continuous bath monitoring
and much more, according to individual
requirements.
For less demanding cleaning tasks,
mechanical methods are suitable. The
‘Primary Wire Wipe’ system (PWW) enjoys
excellent popularity in this field. The wire
to be cleaned passes between two strips
of absorbing tape material that move in
opposite directions. In this way a clean
tape surface is continuously presented to
the wire or strip material.
Equipped with one of the most popular
and universal tools for surface treatment
of wires, cables and rods, the DRB
brush cleaning system for wires, cables,
rod and small pipes is a compact,
eco-friendly and cost-effective system
for the removal of residual scales, swarf
and dust, to reduce excess drawing
agent or to extend tool life of metal
forming machines.
To optimise surface condition both
pre-process and post-process the material
passes through a rotating spiral brush.
Depending on the application and
material the brushes can have nylon,
brass or steel filaments. The rotary
movement of the brush supports the
wiping effect of this well-proven tool.
Further contamination removed from the
wire does not clog-up the brush because
centrifugal force throws a major part
of the removed contamination into the
base of the unit.
Inside a lidded working box two separate
compartments include a rotating unit to
fix a cut-to-length spiral brush and an air
wipe.
Removed dirt is caught in the trough
and collected in a removable, draw-type
container. Following the spiral brush the
air jet nozzle blows off any remaining
loose particles.

With increasing regulations and health
and safety requirements, it is important
to have options and alternatives from
suppliers.
Recognising the demand for a highly
efficient
yet
more
environmentally
friendly alternative to general purpose
flexible PVC, Sylvin Technologies has
developed a series of non-phthalate,
bio-based compounds.
Formulated from renewable feedstock,
Sylvin’s 32 series is formulated with
a plant-based plasticiser rather than
traditional petroleum-based plasticisers
such as phthalates. Its bio-based
compounds have the same feel, flexibility
and ease of processing as traditional
flexible vinyl compounds. Compounds
are available in clear or can be custom
coloured and developed to meet
most conventional PVC compound
applications.
Sylvin’s bio-based compounds provide
the
following
key
performance
characteristics:
•
Reduced density – more parts per
pound
• Improved
plasticiser
migration
properties
•
Process same as GP vinyl
•
Non-phthalate
Key sustainability credentials of the 32
series include:
•
Derived from renewable resources
(non-petroleum-based feedstock)
•
Substantially reduced VOCs
•
Reduced
water
and
energy
consumption throughout life cycle
•
Lower carbon footprint
