Surface treatment with Plasma technology

The task

Plasma technology is based on corona treatment. In contrast to technically less challenging corona treatment systems, plasma treatment takes place in a nitrogen atmosphere.

In standard corona treatment, the plasma discharge is ignited in the air gap between the corona electrode and the component which is used as the counter electrode. The plasma discharge causes different chemical reactions between the ambient air in the electrode gap and the material surface. Ambient air is composed of ca. 78 % Nitrogen, 20 % Oxygen, 1 % Argon and a number of different gases in smaller quantities.

In many applications, the results of a corona treatment can be optimized by increasing the proportion of nitrogen in the treatment atmosphere. The plasma treatment stations from SOFTAL offer just this by injecting Nitrogen into the discharge gap: more precise control of the discharge atmosphere and the treatment results.

Adhesion guaranteed

We are proud of our growing global customer base that includes manufacturers of film production lines, finishers, film producers and research companies.
Naturally, the portfolio of products offered by SOFTAL is just as multi-faceted as our customer base. This is made possible by the modular design of our treatment systems, which allows customer-specific changes and a rapid development of new systems and processes. This ideal starting point allows us to meet customer demands and achieve results. Guaranteed.

Install and forget

SOFTAL has been part of the corona and plasma industry for more than half a century. Our engineers and developers know, what really matters at the end of the production day. Factors like easy maintenance and service, low operating cost, long life and the optimum in operator safety are considered early in the development process to ensure maximum user-friendliness and up-time.

Customer-specific interfaces and solutions

The numerous hardware and software solutions offered by our treatment systems ensure seamless integration into customer-specific systems and processes. Starting from proven standard components, our systems can be modified to suit any material and/or process. We specialize in the surface treatment of your materials – so you can concentrate on your core business.

Material types

There are film materials that require an extremely high-powered plasma discharge to achieve the desired effect, others are so sensitive to electric discharges that they would be destroyed, even in a standard low-power plasma discharge. There is a solution for every film – just ask us.

Reliable service

The name SOFTAL is synonymous with premium quality systems and a high level of customer satisfaction all over the world. Our unique network of comprehensively trained service professionals located in strategically chosen countries allows us to be personally present in international locations in a matter of hours.

Exact control of treatment atmosphere

Plasma is the modern alternative to wet chemical primer applications. The high costs for storage and disposal of chemicals are eliminated as well as the high energy and time consumption of the process steps for primer application and drying. Instead of wet chemicals, this system utilizes Nitrogen, which is absolutely harmless.

Corona stations

The portfolio of products offered by SOFTAL is as diverse as the possible applications of corona technology. Our corona and plasma systems are always based on our tried and tested standard components, but specifically chosen and adopted to meet the demands of your materials and processes.

Corona generators

SOFTAL corona generators are, of course, just as adaptive as our corona stations. It goes without saying that the products of a company that has been successful in the market for decades offer the ease-of-use, robustness, low maintenance and service costs and numerous small and large solutions for smooth everyday production work that you expect form a global player.
