Cable Treater

The purpose of surface treatment of polymer-based cable insulation materials is to increase surface wettability. The low surface energy of polymer based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion, it is necessary to increase the surface energy of the surface of the cable covering to just above that of the material to be applied. Surface treatment with either Plasma or Corona results in improved surface adhesion properties.

Plasma Treatment of Cables
The PlasmaTEC unit is a cost effective method of optimising the adhesion properties of printing inks and coatings onto polymer cable insulations such as PE, PP and PTFE. This in-line treating system has been specifically designed to facilitate easy installation to new or existing production lines. A complete system includes; Plasma Generator, Plasma transformer and Plasma nozzle/s. The PlasmaTEC is CE-marked.

Features
• Directional non-contact treatment, simply add more nozzles to increase treatment area.
• No limit to size of cables that can be treated, each nozzle can treat up to 12mm band width. Use multiple nozzles for wider treatment widths.
• Zero-Speed control for automatic start/stop of treatment.
• High-speed treatment.

Corona Treatment of Cables
The CableTEC unit is a unique and cost effective method of optimising the adhesion properties of printing inks and coatings onto polymer cable insulations such as PE, PP and PTFE. This in-line treating system has been specifically designed to facilitate easy installation to new or existing production lines. A complete system includes; High frequency Generator, High voltage transformers, Air-cooled electrodes, Ozone Filter and customised stand-alone or bench-top treating station. The CableTEC is CE-marked.

Key features
• 360° non-contact treatment.
• Treatment of standard cable diameters from 0.5 to 8 mm (others on request).
• Fully guarded treating station.
• Zero-Speed control for automatic start/stop of treatment.
• Integrated ‘Watt/density’ control to ensure uniform treatment should line-speed alter.
• High-speed treatment up to 600m/min. (Depending on insulating material).
• Available for treatment of “tough” materials such as Teflon and cross linked polymers.
