Wet chemical cleaning systems for wire, strip, tube, cable and rod

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.

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 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.

Bio-based compounds that offer eco-friendly performance

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
