Goodbye Flame Treatment, Hello High Performance Plasma
Dyne Technology, the UK and Ireland’s leading Plasma Treatment technology supplier has worked closely with market leading thermoplastic hose and tube manufacturer, Copely Developments, to upgrade their surface activation process.
Problems of adhesion were not uncommon for Copely Developments when manufacturing their extruded hoses, tubes and profiles for many applications from pneumatics, air brakes, fire detection systems to garden hoses. Surface activation prior to printing is critical as without it, the inkjet print simply rubbed off. Copely Developments Ltd contacted Dyne Technology when seeking to replace their old inefficient flame treatment system.
The engineering team at Copely explored alternatives to Flame Treatment because of the unreliable performance it delivered and the lack of control it allowed over their production process. The lack of consistent results presented huge issues as safety critical markings are printed onto the fire detection tubes which require a strong bond to ensure high print resiliency.
Alongside poor print adhesion the high running cost of Flame Treatment was another important deciding factor for Copely Developments. The Flame Treatment system needed frequent gas bottle replacement. The use of a naked flame in Copely’s thermoplastic extrusion facility presented a significant health and safety concern, this is often reflected in the higher cost of buildings insurance to manufacturers using this process.
Why Plasma Treatment?
The hoses are produced on two separate extrusion lines with speeds ranging from 5 – 30 metres per minute and a flexible and easily repeatable, in-line method of surface activation was essential.
Working closely with Copley’s engineers the Dyne Technology technical team conducted initial tests at the Dyne Technology Technical Centre and established that the most appropriate surface treatment method was atmospheric Plasma. The next step was to carry out an on-site on-line production trial with the selected equipment to satisfy both the Technical and production teams at Copely Developments.
“The Dyne Technology team provided fantastic customer support in helping us determine the best method of surface activation for our manufacturing process by conducting a “no fuss on site trial” on our production line. We are thrilled with the high performance as it provides consistent, reliable results and is much cheaper to run than the flame system installed previously. Plasma Treatment provided us with a repeatable method of surface activation that we can trust to provide consistent results every time. – Steve Walton, Operations Director
