Plasma Systems

Voltrium Systems is proud to represent Diener Electronic in the South East Asia Region for their quality plasma systems. Diener Electronic is an innovative company in the field of plasma technology and an international leader in the production of high quality, low cost plasma systems, both low pressure and atmospheric. Receiving worldwide acceptance, these plasma surface treatment systems have found applications in the electronic, plastic, and medical fields.

What is Plasma

When energy is continuously supplied to a matter, the temperature of the matter increases and it passes from solid state to liquid and finally to gaseous state. If the energy supply continues, the existing atomic shell disintegrates and charged particles are created (negatively charged electrons and positively charged ions). This mixture is referred to as plasma or the "fourth state of matter".

In short: Change of the aggregate state under energy supply: solid ⇒ liquid ⇒ gaseous ⇒ plasma

Natural plasma occurs for example in lightning, polar lights, flames, and the sun. Artificially created plasma is found in neon tubes, welding processes and in flash bulbs, among others.

Fields of Application

Plasma technology offers a wide range of options for surface modification. Diener manufacture plasma systems in different versions (size, processes, controls, etc.) Plasma systems are differentiate between low-pressure plasma and atmospheric plasma.

Plasma is used in applications where it is important to combine materials or to specifically change their surface properties. Nowadays, plasma technology is established in almost all sectors of industry, and new applications are being developed constantly. This future-oriented technology allows for modification of a wide range of surfaces. Thus, many different applications are feasible, for example:

Plasma Processes

Materials Cleaning Activation of Materials Etching Materials Coating of Materials

Ion bombardment cleans surfaces physically (sputtering) and, depending on the gas, also chemically. The contamination is vaporized and sucked away.

Plasma treatment of a plastic surface with eg. oxygen, radicals are being formed which lead to a good adhesion of finish and glue.

Etching of the surface with a reactive process gas, material is removed, vaporized and sucked off. Therefore the surface area is enlarged.

A monomer gas is introduced to the plasma chamber, because of plasmapolymerization, layers will be deposited on the surface.

By altering process variables including pressure, power, process time, gas flow, and composition, the impact of the plasma changes. Plasma systems are widely used and has become an important industrial process for modifying polymer surfaces properties such as adhesion, friction, penetrability, wettability, dyeability and biocompatibility. With the help of a plasma system, several effects can therefore be achieved in a single process step.

 

Plasma Systems

Low Pressure Plasma Systems

In the low-pressure technology, gas is excited in a vacuum by a supply of energy.
This results in energetic ions and electrons, as well as other reactive particles,
which constitute the plasma. It can be used to effectively alter surfaces.

Atmospheric Pressure Plasma Systems

With atmospheric plasma technology, gas is excited by means of a high voltage
under atmospheric pressure, such that a plasma is ignited. The plasma is
expelled by compressed air from the nozzle.
