Plasma Cleaning Plastic before Ultrasonic Welding

pdf downloadDyne Technology Ltd, the UK and Ireland’s Number One supplier of Plasma Treatment technology, look at how Plasma improves the surface cleanliness of plastics and how this was beneficial for our customer prior to ultrasonic welding.

A customer approached Dyne Technology when searching for a green and economical method of cleaning a 3D polyolefin component prior to the ultrasonic welding of small plastic brackets. Plasma Cleaning offers a clean, green alternative to nasty environmentally damaging solvent based cleaners which the customer desperately wanted to avoid.

Why Plasma Cleaning?

Many are aware that Plasma provides a fast and effective treatment for the removal of organic contaminants from the surface of metal, glass and ceramic components; however, it is not widely known that Plasma is also excellent for removing organic contaminants from the surface of plastics.

How does it work? Plasma is created when a gas (usually compressed air) is subjected to a high-energy discharge: the gas breaks up into electrons, ions, highly reactive free radicals, short wave UV light photons and other excited particles. When these species are excited by a high-energy discharge, they effectively scrub the surface to be cleaned.

The type of Plasma Treatment equipment required is heavily dependent on the component undergoing treatment and your manufacturing process. In this instance, Atmospheric Plasma was the cleaning method of choice, but Vacuum Plasma also provides a uniform and reproducible process for the removal of organic contaminants from the material’s surface.

Atmospheric Plasma Surface Cleaning

Both Vacuum and Atmospheric Plasma can be used for surface cleaning plastics, however which one is right for you is highly dependent on your application.

Atmospheric Plasma offers an excellent option for those looking for targeted surface cleaning, perfect for our customer’s application of applying small plastic brackets.

Atmospheric Plasma can easily be integrated with both new and existing production lines; typically, integration with automation offers an excellent solution for targeted treatment areas due to the repeatability and consistency of treatment offered.

The Dyne Technology team has vast experience designing a breadth of robotic Plasma Treatment units, including robotic Atmospheric Plasma cells. When integrating Atmospheric Plasma with automation, the Dyne Technology engineers are always keen to ensure that the unit is both easy to operate and maintain alongside having a compact design and small factory footprint.

The Atmospheric Plasma system is an economical, environmentally friendly and efficient method of surface activation. Our customer required only a single nozzle, however if the need arises, production can easily be increased with additional nozzles. The unit features a timer mode and boasts simultaneous and independent nozzle operation for true flexibility. Adjustable parameters allow for reliable and consistent surface activation.

Dual Performance Technology

Did you know that following continued treating, Plasma will also “activate” the surface of plastics? Plasma Surface Activation is a highly effective, long lasting method of increasing the surface energy of plastics and rubbers, such as Polypropylene (PP) and Polyethylene (PE).

eco_friendlyThe increased surface energy allows for better wetting of adhesives, coatings and inks alongside contributing to a better chemical affinity between the adhesive and the substrate.

It’s important to note that Plasma Treating doesn’t alter the bulk property of the material, in fact, you won’t even be able to tell we’ve been there.

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.

copely-developmentsProblems 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.

warning-838655_960_720Alongside 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.

copely-developments-nozzleWorking 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
