Atmospheric Plasma Systems

atmospheric_sys

Atmospheric plasma systems are designed for the applications of activation, cleaning and deposition of materials. The equipment is especially designed for the process of changing surface chemistry of one surface selectively without affecting another surface in the close proximity to it. It also has the ability to process low surface energy materials that are sensitive to damage from electrostatic discharge.

Atmospheric pressure plasma is suitable for a wide range of applications. Primarily, the systems are optimized for high volume plasma treatment of communication device surfaces in manufacturing. For example in the cleaning and activation of polymers, metals, ceramic, glass and composite materials. Due to their unique innovative design, atmospheric pressure plasma systems are suitable for use with robots and for integration in existing, automated production lines.

How Atmospheric Plasma Systems Are Used

Atmospheric plasma is moved across the part which exposes the treated area to a stream of ionized gas plasma. The speed and distance of the applicator from the part determines the shift in surface energy or amount of treatment the target area receives.

While the plasma cleans and activates the surface on a molecular level, an additional cleaning effect is provided by blowing away loose particles. Atmospheric plasma systems allow for a truly continuous plasma process. The plasma applicator is connected to the supply unit with a flexible cable that allows for easy integration into existing robotic controlled manufacturing lines or moving the plasma source relative to the part.

Atmospheric Plasma Applications

Plasma Cleaning

Atmospheric plasma cleaning is used to remove thin films of foreign material from a surface.  This is common in a casting or machined component to remove a thin film of oil from it.  This film of oil can be cleaned for a secondary process of welding or an adhesive application.

Plasma Activation

Atmospheric plasma activation is used to increase the bond strength of an adhesive to a polymer.  This process is often completed by the same automation tool that dispenses the adhesive.  The Atmospheric source is moved across the surface of the part to be activated at a speed of 100 to 800 millimeters per second at a distance of 2 to 10 millimeters until the desired activation is achieved.

Plasma Coating

Atmospheric plasma deposition is used to plasma coat parts in a plasma process without the use of a vacuum system.  The atmospheric plasma source is integrated with a monomer dosing pump and an introduction nozzle to incorporate monomers in the plasma.  This method of coating is able to be controlled and repeats well.

Corona Plasma

Corona Plasma is a variation of atmospheric plasma generation that is produced by blowing air through a series of high voltage arcs causing the air to ionize.  This ionized air can be used to provide an increase in surface energy in non-conductive surfaces.  The advantages of these types of plasma sources to produce surface treatment is low cost and the use of room air as a feed stock.  The disadvantages of these plasma sources is they do not work on conductive materials, the plasma is lower in density to other sources and the high voltage arc can be an ignition source.  The low cost and moderate shift in surface energy provided by a corona plasma technology can make it an option for consideration in some manufacturing solutions.
